SUMMARY 
 
 INTRODUCTION 
 
 The Marine Protection, Research and Sanctuaries Act of 1972 (Public 
 Law 92-532) authorizes the Secretary of Commerce with Presidential 
 approval to designate ocean areas with distinctive conservation, 
 recreational, ecological or aesthetic values as marine sanctuaries. 
 The Flower Garden Banks, lying more than one hundred miles 
 offshore Texas and Louisiana in the Gulf of Mexico, have been nominated 
 as a candidate site for marine sanctuary designation by Texas State 
 Senator A.R. Schwartz in conjunction with the Texas Coastal and Marine 
 Council. The Banks are biologically unique and important. They contain 
 not only the northwestern most living reefs on the Gulf of Mexico Outer 
 Continental Shelf, but also many important habitats for unusual marine 
 organisms. Included in these habitats is the East Flower Garden Brine 
 Seep System, appropriate for study because of its (1) unique physical, 
 chemical, and biological systems; (2) the extreme fragility of 
 the system; and (3) the importance of the systems in general for science 
 and in particular for the understanding of the evolution of benthic community 
 structure. 
 
 The National Oceanic and Atmospheric Administration, Office of 
 Coastal Zone Management, in cooperation with scientists from Texas A & M 
 University (TAMU) and Harbor Branch Foundation, Inc. (HBF), will sample 
 in the brine seep and adjacent canyon and hard-bottom community resources 
 and equipment provided by HBF. This manual presents the operations plan 
 for this resource sampling survey.

 OFFICE OF COASTAL ZONE MANAGEMENT 
 
 The National Oceanic and Atmospheric Administration (NOAA), Office 
 of Coastal Zone Management (OCZM) was established to administer the 
 Coastal Zone Management Act of 1972 (P.L. 92-583). In addition to this 
 responsibility, the Secretary of Commerce delegated the authority to 
 OCZM to administer Title III of the Marine Protection, Research and 
 Sanctuaries Act of 1972 (P.L. 92-532). 
 
 The authority granted under Title III is for the purpose of setting 
 forth the procedure by which areas may be nominated as marine sanctuaries 
 and the concepts, policies, and procedures for the processing of nominations 
 as well as for the selection, designation, and operation of a marine 
 sanctuary. 
 
 Through its desire to undertake an active role in management and 
 research in the proposed East and West Flower Gardens Marine Sanctuary, 
 OCZM is acting cooperatively with TAMU and HBF in planning, preparation, 
 and execution of this deepwater resource survey. 
 
 As project manager and coordinator, OCZM is providing technical 
 personnel responsible for designing and executing the project, contacting 
 the necessary outside scientific experts and is funding part of their equipment 
 shipping and personnel travel expenses.

 TEXAS A & M UNIVERSITY 
 
 The University's College of Geoscience's Department of Oceanography 
 is involved in oceanographic research, including surveying and sampling 
 of unusual marine biotic communities. The Department is providing 
 technical personnel who are responsible for developing the scientific 
 plan for the mission, preparing and analyzing all samples collected, 
 constructing or making available any supplies or equipment needed for 
 scientific research, and for writing the final cruise and scientific report. 
 
 HARBOR BRANCH FOUNDATION, INC . 
 
 The Harbor Branch Foundation, Inc. (HBF), is a not-for-profit 
 organization established in 1970 primarily for research in the marine 
 sciences and for the development of oceanographic tools and systems for 
 undersea research. Outlined below are HBF's program objectives: 
 
 1. Accumulating and computerizing knowledge in the field of oceanology, 
 particularly as it applies to the effects of pollution. 
 
 2. Sponsoring and engaging in scientific research and development 
 for the purposes of making inventories and observing the behavior of 
 marine plants and animals through various stages of their life cycles 
 in unpolluted and polluted waters. 
 
 3. Developing new engineering tools and improved safety equipment for 
 marine and oceanographic research and operating laboratories for the 
 furtherance of such research. 
 
IV 
 
 4. Developing methods for changing the character of pollution, by 
 eliminating the harmful effects and by utilizing the nutrients and 
 beneficial effects. 
 
 5. Sponsoring and engaging in underwater archaeology projects 
 through the use of new engineering tools and methods. 
 
 6. Preparing and distributing publications, research materials, 
 lectures, and seminars which serve to disseminate knowledge of marine 
 plants and animals and ocean engineering research and development. 
 
 HBF is providing technical personnel, both surface and underwater 
 vessels, and equipment to meet the operation requirements for proposed 
 East Flower Gardens Bank Brine Seep Assessment. 
 
I. OVERVIEW OF THE OPERATION 
 
 The area to be surveyed is part of the proposed East and West Flower 
 Gardens Marine Sanctuary, located approximately 110 nautical miles (nm) 
 southeast of Galveston, Texas, and 120 nm south of Cameron, Louisiana. 
 The proposed sanctuary would include the waters overlaying the banks 
 and extending to within 4 nm of the 100 m (328 ft.) isobaths of each 
 bank, a total area of approximately 173.25 square nautical miles. Personal 
 communication with Thomas J. Bright and Eric N. Powell (Texas A & M 
 University) indicates the East Flower Garden (EFG) Brine Seep system 
 (Figure 1) is biologically important for the following reasons: (1) the 
 bacteria of the seep oxidize sulfide in high salinity water at low light 
 levels. Data suggest that a bacterial association, under the conditions 
 found here, occurs rarely, if at all, anywhere else; (2) the benthic 
 communities found downstream of the seep may exist primarily on sulfur 
 bacteria as a food source. As such, community composition and structure 
 are exotic and population densities are unusually high (in fact, the 
 communities are analogous to the Galapagos Rift hydrothermal vent community 
 in this regard—see Ballard et al . , 1979); (3) one of these communities 
 --the one associated with the white sulfur bacterial mat in the overflow 
 canyon--is absolutely unprecedented. This community is dominated by 
 gnathostomulids, a relatively unknown phylum restricted to sulfide system-like 
 environments. A community dominated numerically (and possibly in biomass 
 also) by this phylum has never been reported before, and in fact, may be 
 unique. There is every reason to believe it is a "living fossil" community;

(4) the gnathostomulid species may themselves be unique. We have not 
 yet consulted with a systematic expert in the group, but the large size 
 of the organisms involved, coupled with the general knowledge of the 
 group which we do have, leads us to believe that the species may indeed 
 be undescribed. Thus it is clear that the biological associations found 
 at the EFG brine seep are unusual and deserving of careful study. 
 
 II. MISSION OBJECTIVE 
 
 Doctors Bright and Powell of Texas A & M University, with the 
 support of the Office of Coastal Zone Management (OCZM) will use Harbor 
 Branch Foundation facilities and equipment, including the submersible 
 JOHNSON-SEA-LINK (J-S-L) to undertake a series of dives to quantitatively 
 sample marine resources in the East Flower Garden Bank Brine Seep System, 
 near the overflow canyon and coral reef, and adjacent soft-and hard-bottom 
 communities. J-S-L diver 1 ock-out capabilities will be used to collect 
 any necessary biological samples for species identification. Video tape 
 and still photography will be used to document observations.

 Dr. Nat Eiseman of HBF will be conducting the required 
 observational transect from the shallow (coral reef) area 
 of East Flower Garden Bank to a point below the brine 
 seep. He will also be conducting a series of lock-out 
 dives at 100', 125', 160', 200' and at selected points 
 around the "brine lake" and "canyon". These dives are 
 necessary to augment the transect work. The distribution 
 and species of algae collected will be reported. Light 
 meter and thermograph instruments will be deployed in the 
 study area and recovered at the conclusion of the mission. 
 
 Dr. Robert Jones of HBF will be making observations and 
 photographic recordings of marine fishes in and around the 
 brine seep. This will be a continuation of work begun by 
 
Dr. Bright. Of special interest will be the behavior of 
 these fishes toward the brine stream. 
 
 15 September Depart operations area. Return to Galveston to offload 
 scientific party. R.V. Johnson returns to Link Port. 
 
 18 September R.V. Johnson arrives Link Port. 
 
 C. Training Requirements 
 
 No specific training will be required for this operation as HBF will 
 be using experienced staff familiar with the equipment and procedures 
 required for this mission. 
 
 D. Routine Reports 
 
 The only routine report which will be made during the mission is a 
 scheduled call to Link Port each morning 0900 to inform HBF of the happenings 
 of the day before and the scheduled activities of the day. Because a 
 NOAA Representative will be on-site throughout the operation, reports 
 will be submitted to OCZM on an as-appropriate basis, followed by a report 
 at the end of the operation. 
 
 E. Limiting Environmental Conditions 
 
 Limiting environmental conditions which have a significant impact on 
 
 the execution of the mission are: 
 
 Sea State - The surface support vessels cannot operate in a Sea 
 State greater than 5 as they are unable to launch or 
 recover the J-S-L. Therefore, any time such condition 
 arises, the operation will be halted until calmer 
 seas prevail. The weather forcast will be monitored on 
 Channel WX and NOAA will contact the National Weather 
 Service to inform them of the planned mission so 
 they may provide up-to-date information upon request. 
 
 Currents- Because the operational propulsion of the J-S-L is 
 
 1.5 knots, any curents over 1.5 knots will result 
 in review of the planned dive. 
 
 Turbidity- Reduced visibility in the water could have an impact 
 
 on good photographic data and limit submersible operations. 
 
10 
 
 F. Alternative Mission Plans 
 
 If the Sea State is such that the vessels cannot operate, no mission 
 plans can be substituted as the purpose of this operation is to conduct a 
 biological assessment which requires vessel operations. If operating 
 days are lost due to weather, first priority will be given to TAMU for 
 completion of their research. 
 
 G. Scientific Reports 
 
 HBF will provide final reports on their algae and fish investigations 
 by December 30, 1980. 
 
 TAMU will provide NOAA with a cruise report by November 1, 1980 and 
 a final scientific report in publishable form by August 31, 1981. 
 
 IV. Organization and Personnel 
 
 Figure 4 illustrates diagrammatical ly the organization of the participants 
 in the operation. 
 
 A. Chain of Command and Responsibilities 
 
 Director, Operations and Enforcement (OCZM )- is responsible for 
 overall program planning and coordination. He will be advised by the 
 NOAA representative and the operations director of any event which could 
 affect the safety of the open-sea operation. Substantial alterations to 
 the mission plan must have the prior approval of the Director for Operations 
 and Enforcement. He will be responsible for keeping the Assistant 
 Administrator for Coastal Zone Management informed of all ongoing activities. 
 
 NOAA Representative - is responsible for the safe and efficient 
 operation of the mission. Safety of the operation will be foremost in 
 his mind, and he will keep the Director, Operations and Enforcement 
 
11 
 
 informed of any problems affecting the mission. He may, in the event it 
 is necessary and only under circumstances where he observes that the 
 safety of personnel or failure to observe pre-arranged agreements arises, 
 suspend further open-sea operations. 
 
 Operations Directo r - has the responsibility for the overall safe 
 and efficient operation of the mission. Safety of the operation will be 
 foremost in his mind, and he will keep the NOAA Representative advised of 
 any event which could alter the mission's plan or affect the safety of 
 the operation. He is also responsible for the coordination of launching, 
 operating, tracking and recovery of the submersibles. He will make the 
 final decision as to the readiness of the submersible to operate and 
 will direct those technical personnel responsible to him in carrying out 
 their assigned duties and assure that all diving equipment is functional 
 and properly maintained. 
 
 Chief Scientist - is responsible for the scientific mission, and for 
 coordinating the science plan of the mission. He will coordinate the 
 activities of the scientists with the Operations Director and keep him 
 informed of any alteration which would affect the daily operations 
 schedule. 
 
 Support Ship Captain - is responsible for the safe operation of the 
 support ship and its equipment and personnel. He will coordinate with 
 the Operation Director all support ship activities with respect to 
 submersible operations.

 2. J-S-L Handling System for R/Y JOHNSON 
 
 The handling system consists of one hydro crane, two capstans, a 
 battery pod footprint, two vertical supports to support the after end 
 of the J-S-L and various padeyes, chains, and turnbuckles for securing 
 the J-S-L to the deck. In addition to this the R/Y JOHNSON has aluminum 
 pipe back stops with gates that can be moved through 90° to accommodate 
 an inner and outer tiedown position. 
 
 The hydro crane was designed principally for the launch and 
 retrieval of the J-S-L over the stern of a small ship. It can be used 
 for other purposes provided the design loads are not exceeded. 
 
 It is constructed entirely of aluminum alloy 6061-T6 welded with 
 5356 electrode and has a 100 percent hydraulically operated system, 
 incorporated in the crane head is a hydraulic braking system that dampens 
 roll and pitch of the suspended load when it is in the housed position. 
 
16 
 
 The R/V JOHNSON receives its hydraulic power for the submersible 
 handling system from two sunstran 55 G.P.M. pumps which are clutched 
 to the frame of each main engine. The crane hydraulic power can be 
 cross-connected with the forward hydraulic system which furnishes power 
 to the bow thruster, anchor windless, and cargo crane.

 Description 
 
 Normally a lock-out dive from the J-S-L will consist of one tethered 
 diver who is tended by another diver from inside the dive compartment. 
 
 As the J-S-L approaches a lock-out site, the pilot positions the 
 J-S-L on the bottom, pointing into the current at the work site, reports 
 his depth to the support ship and requests permission to flood down. 
 
 After the divers are dressed-out and report ready for lock-out, 
 the pilot requests permission from the surface to blow down. The divers 
 secure their 02 bleed and C02 scrubber, check "A" hatch undogged and 
 report to the pilot standing by for blow down. Then the pilot initiates 
 a count down over the underwater telephone and the J-S-L intercom. The 
 diver- tender controls blow down in the diver compartment and maintains 
 a 100* per minute descent rate. The rate of descent is monitored by 
 the pilot. (If necessary, the pilot can override the tender). When 
 the diver compartment equalizes and the "A" hatch seal is broken, the 
 pilot reports to the support ship. 
 
 When the "A" hatch seal is broken the diver- tender secures the 
 blown down, pushes "A" hatch of the manway and gives the diver a last 
 minute check before he enters the water. 
 
34 
 
 When the diver initially enters the water he gives the J-S-L a 
 lift test by trying to lift it off the bottom, and makes a communica- 
 tion check with the pilot before leaving and diver compartment. The 
 pilot reports to the support ship that the diver is out. 
 
 The diver is continuously monitored by the pilot and observer 
 throughout the dive. The diver's bottom time is kept by the diver- tender, 
 pilot, and support ship. The diver's umbilical is tended throughout 
 the dive by the diver- tender. 
 
 When the diver returns to the J-S-L at the completion of his 
 task, the diver-tender takes up the umbilical and assists the diver 
 through the manway, lifts and dogs "A" hatch, drops "B" hatch and 
 over pressurizes the diver compartment 5'-10'. The pilot reports the 
 over-pressurization depth in the diver compartment to the support ship 
 and requests permission to surface. 
 
 The divers blow the bilge ballast tanks and the pilot commences 
 blowing the diver ballast tanks. The pilot reports to the support 
 ship when the ballast tanks are blown dry. 
 
 As the J-S-L leaves the bottom, the divers commence venting the 
 diver compartment to their first stop. The venting is monitored by the 
 pilot and observer. Venting can be controlled either from the pilot's 
 sphere or the diver compartment. 
 
35 
 
 2. Surface Support 
 
 a. Communications will be maintained between divers and 
 pilot during swimming excursions, via hard wire. 
 
 b. Communications will be maintained during lock-out dives 
 from diver to submersible to R/V JOHNSON. 
 
 c. Should prolonged decompression or treatment be necessary 
 
 following a lock-out dive, the submersible will 
 
 return to the surface, and be mated to the 
 
 decompression chamber aboard the 
 R/V JOHNSON. 
 
 d. All diving will be via diver lock-out.

 b. Sonar System (J-S-L) 
 
 The Straza Industries Model 500 CTFM (Continuous - Transmission - 
 Frequency - Modulated) sonar electronic stack is mounted on the forward 
 end of the electronics equipment rack in the center of the sphere. The 
 training mechanism, with hydrophone and projector attached, is mounted on 
 top of the pilot's sphere hold assembly. The high resolution sonar can 
 detect and view underwater objects at all bearings and at ranges 
 
 from 3 to 1500 yards. The system provides both audio and visual outputs 
 and has the capability of maintaining simultaneous contact with multiple 
 targets and markers or transponders. 
 
 c. Transponders 
 
 One Straza transponder Model 7030 is attached to the support 
 ship's underwater electronics tower and is powered by 14 VDC from the 
 electronics control station on the bridge. When the Straza transponder 
 is interrogated by a signal from the submersible' s sonar it transmits 
 a pulse, shows up on the sonar PP1 scope as a "blip" and indicates range 
 and relative bearing to the surface ship. A second Model 7030 trans- 
 ponder is carried on the support ship. It is battery powered and can 
 be used as a back up or a location marker at depths to 100 feet. 
 
44 
 
 d. Loran C 
 
 The R/V JOHNSON will use a Loran C (Two Northstar 6000's) 
 for navigation. 
 
 e. Tracking 
 
 Tracking the J-S-L is accomplished with a Honeywell R57 indicator. 
 This unit displays a signal received from a beacon mounted on J-S-L. 
 The R57 displays two channels at one time on a bridge mounted cathode 
 ray tube. This unit shows range and bearing and can track and display 
 both submersibles simultaneously. 
 
 2. Undersea System 
 a. Pingers 
 
 The Straza pinger is mounted in a bracket on the after "A" frame 
 and is turned on by a saltwater activated switch. The Helle pinger is 
 a similar bracket on the after "A" frame and is switched on by closing 
 a switch on the sphere electrical control panel. 
 
 These pingers are tracked by the support ship with a Straza 
 marker receiver Model 9010/MRM-503 passive tracking sonar. Accurate 
 relative bearings out to 2500 yards on the Straza pingers are normal. 
 
45 
 
 b. Doppler Sonar Navigation System 
 
 The Sperry SRD-101 Doppler Navigation System consists of the 
 following major components: The transducer assembly, the electronics 
 pressure can, the control and indication unit, and the magnesyn compass. 
 
 The SRD-101 employs beams of continuous wave ultrasonic energy, 
 directed obliquely at the ocean floor, to obtain true speed and dis- 
 tance covered over the bottom in the fore-aft and starboard-port direc- 
 tions. Speed and distance are displayed on a heading-drift in- 
 dicator, along with desired magnetic course and actual magnetic heading. 
 
 d. Echo Sounder 
 
 The data marine digital echo sounder is mounted on top of the 
 sonar stack in the forward part of the pilot's sphere. Power is applied 
 by closing a switch on the sphere electrical control panel. A Model 
 3023 transducer is mounted on the after bottom "A" frame. 
 
 VII. Emergency Procedures 
 
 A. Advance Notification 
 
 The Coast Guard base located in New Orleans, La., has been 
 informed in advance of the operation mission plans and will be 
 monitoring the area in conjunction with their role prescribed by the 
 Rules and Regulations of the Marine Sanctuary. Notification of the 
 operation will be placed in the Notice to Mariners.

 diver decompression accidents. A medical technician will be on-site throughout 
 the diving operations. The DDC facility and the medical technician, who will 
 operate the chamber, will meet all the requirements described in NOAA Circular 
 75-88. Additional medical treatment may be provided aboard the R/V JOHNSON 
 dispensary facility. 
 
 D. Possible Emergencies and Planned Responses 
 
 HBF has developed the following four rescue systems to assist J-S-L- 
 submersibles in emergency situations: 
 
 1. SEA GUARDIAN/CORD - This unmanned tethered vehicle can be fitted 
 with an hydraulic cable cutter or can be used to carry a drop-lock mechanism 
 attached to a hauling wire. 
 
 2. J-S-L submersible - A second J-S-L submersible can be fitted with 
 
 a reel of hauling wire with a drop-lock mechanism on one end and an inflatable 
 buoy on the other for emergency rescue. 
 
 3. Lock-out diver - A diver can be locked out of the disabled submersible 
 or a second J-S-L submersible to use a cable cutter or for general reconnaissance. 
 
 4. Emergency buoy - Each J-S-L submersible carries a self deployed 
 emergency buoy which carries 0.19 inch-Phi 11 ystran rope for attaching a hauling 
 wire (see Appendix 2 for details). 
 
 Additional details on emergencies including fire, flooding, entanglement, 
 etc. can be found in Appendix 2.

 U.S. Coast Guard - see Section VII., B. and Appendix 3. 
 
 2. If any emergency situation arises the NOAA 
 Representative on-site will report to the Director, 
 Operations and Enforcement of Marine Sanctuaries who will 
 immediately brief the Assistant Administrator for 
 Coastal Zone Management, the Director of the 00E Office, 
 the NOAA Diving Coordinator, and the Director of Public 
 Affairs on the emergency, the steps which have been taken 
 and planned remedial action. Following the close of the 
 emergency situation the events which occurred will be 
 documented for the record.

 Roger W. Cook's career as an underwater specialist began while in the 
 Navy's underwater demolition team. The use of hand-held sonar and 
 Swimmer Propulsion Units from Navy Fleet Submarines were among his 
 duties. Following his naval service, Mr. Cook worked for the Pacific 
 Missile Range on Kwajelein in the Marshall Islands recovering missile 
 wreckage and components. During this time, he was trained by 
 representatives of Perry Submarine Builders as pilot of the PC3A sub- 
 marine; a dry, two-man submersible rated to 300 feet. He logged more 
 than 70 dives in this submersible. From 1966 to 1972, Mr. Cook was 
 employed by Ocean Systems, Inc., as Chief Pilot for the Link-designed 
 diver lock-out submersible DEEP DIVER. He logged more than 80 dives 
 at sites ranging from Newfoundland to Europe and the Caribbean. Most 
 of these dives were lock-out, two were saturation dives. DEEP DIVER, 
 depth rated to 1350 feet, was used for work with the U.S. Navy under 
 the Search and Recovery contract. This work also included use of an 
 ADS IV (Advanced Diving System) to recover crashed aircraft and other 
 objects in depths greater than 200 feet. In 1972, Mr. Cook joined 
 Perry Submarine Builders as Project Supervisor for the designing and 
 supervision of construction for the complete outfitting of a one-atmos- 
 phere, 5-man personnel transfer bell. He then procured and adapted a

 J-S-L- Emergency Procedures 
 
 DDC Facility and Life Support Systems 
 
J-S-L Emergency Procedures 
 
 Commu nications 
 
 1. If voice communications are lost on the underwater 
 telephone for fifteen minutes, the J-S-L pilot 
 should surface with extreme caution as soon as 
 practicable, attempt to communicate on the way up 
 by both voice and C.W., establish communications 
 via FM transceiver when surfaced. 
 
 2. In the event that communications are lost on the 
 surface and the support ship is not in sight, turn 
 on the flasher and attempt to communicate on FM 
 transceiver with any station on the emergency 
 Channel Fl (Channel 16) . If you suspect that both 
 FM transceivers are out of commission and believe 
 the support ship to be within a two-mile radius, 
 consider diving the J-S-L to 50 feet and attempting 
 contact on the underwater telephone or via C.W. 
 
 3. If the J-S-L gets entangled on the bottom, commun- 
 ications between the sphere and the dive compart- 
 ment should be made on the sound powered phone and 
 communications to the support ship should be held 
 down to a minimum to conserve the battery. The 
 underwater telephone uses power as follows: 
 
 Mode Current 
 
 a. Receive 1 amp. 
 
 b. Transmit Near 1 amp. 
 
 c. Transmit Medium 8 amp. 
 
 d. Transmit Far 17.5 amp. 
 
 4. Transmit time can be held to a minimum using the 
 codes outlined in Appendix "C" .

Flooding 
 
 1. Uncontrollable - It is highly unlikely that J-S-L 
 
 could encounter an uncontrollable flooding situation 
 without having a collision with another vessel or 
 submerged object. It is also doubtful that the diver 
 compartment would be penetrated in a collision. One 
 of the main ballast tanks could be pierced and rendered 
 almost: unless, but the J-S-L could surface on the 
 other tan* and if necessary, the battery pod could ^e 
 dropped. The most vulnerable part of the J-S-L is 
 the plexiglass sphere that could crack if it comes in 
 contact with another hard object at a combined speed 
 of 1.81 knots oh the surface to 4.77 knots at 1000 
 feet. Evidence to date shows that the hull may crack 
 but would probably stay together and not leak due to 
 external pressure holding it in compression. If this 
 was the case, the J-S-L should not attempt to surface 
 above 100 feet. At that depth divers would rig se- 
 curing lines to the J-S-L frame to be winched under 
 the handling system for recovery. The action to be 
 taken depends on the situation as follows: 
 
 a. If the diver compartment has a seal and the pilot's 
 sphere has uncontrolled flooding : 
 
 (1) Blow main ballast. 
 
 (2) Release the emergency buoy. # 
 
 (3) Thruster up if possible. 
 
 (4) If the crack is in the lower two- thirds of 
 the sphere, and water is coming in, pressurize 
 as necessary. 
 
 (5) Blow all remaining ballast. 
 
 (6) Inform the support ship and diver compartment. 
 
 (7) Secure electrical power as dictated by the 
 flooding. 
 
 (8) Don emergency regulators and face masks 
 as necessary. 
 
 (9) Drop the battery as a last resort. 
 
 (10) When the J-S-L arrives on the surface, stay 
 in the submersible, turn on the flasher, 
 communicate if possible and maintain positive 
 buoyancy until help arrives . 
 
 2-2 
 
b. If the pilot's sphere has a seal and the diver 
 compartment has uncontrolled flooding: 
 
 (1) Blow main ballast (use gas bank not needed 
 for pressurization of diver compartment) . 
 
 (2) Check selection of correct supply to blow 
 and mask 5-way valves. 
 
 (3) If necessary, divers should be on the re- 
 breather or mask system. 
 
 (4) Report to surface ship. 
 
 (5) If flooding is rapid, pressurizing of the 
 dive compartment may be required. 
 
 (6) Prepare to drop the battery (complete 
 flooding of the diver compartment will 
 require dropping the battery and blowing 
 main ballast tank dry to achieve positive 
 buoyancy) . 
 
 (7) Secure electrical power to the diver 
 compartment. Communicate via the sound- 
 powered phone. 
 
 (8) If main ballast tanks are dry and the J-S-L 
 is still negative, dropping the battery will 
 produce a positive buoyancy of at least 700 lb. 
 Switch to emergency battery and inform the 
 surface, then drop the battery. Ascent will 
 
 be uncontrolled. 
 
 c. In the event of surface collision, it is possible 
 that one or both main ballast tanks might be damaged 
 as well as the pilot sphere, and dropping the battery 
 would not provide positive buoyancy. Once the J-S-L 
 was on the bottom, personnel in the pilot's sphere 
 could tranfer to the diver compartment as a last 
 resort. Communication with the surface would almost 
 certainly be out and probably with the dive compartment 
 The procedure would depend on the pilot's assessment 
 
 of damage, but would resemble the following: 
 
 (1) Blow the emergency buoy. 
 
 (2) Establish communications with the divers. (A 
 written message could be held against the back 
 of the sphere and read through the forward view- 
 port in the diver compartment) . Inform them of 
 transfer attempt. Prepare, for pressurization. 
 Close sphere access line hull stop in diver 
 compartment. 
 
 2-3 
 
(3) Open air cross-connect. 
 
 (4) Open oxygen cross-connect. 
 
 (5) Select the desired supply with the .pilot's 
 5-way valve and line up the emergency 
 cross-connect manifold so the divers can 
 pressurize using the sphere access line 
 hull stop. 
 
 (6) Pressurize the diver compartment and have 
 a diver stand by pilot's sphere hatch. 
 
 (7) Complete flooding sphere as neccesary to 
 allow hatch to be opened. 
 
 (8) Send observer back to diver compartment with 
 standby diver. Have diver return when "A" 
 hatch is clear; swim back to diver compartment. 
 
 (9) Have diver remove all lead ballast and all 
 unnecessary equipment. At this point, it is 
 conceivable if only one main ballast tank is 
 damaged, the battery is dropped and all other 
 tanks are dry that the J-S-L might become 
 slightly positive. The diver should be prepared 
 to return quickly. 
 
 (10) If the J-S-L remains on the bottom, the crew 
 would have to use the diver compartment as 
 an ambient pressure habitat until help arrived. 
 With four persons and no electrical power, 
 CO2 scrubbing would have to be accomplished by 
 other means. If the inhalation hoses of the 
 rebreather masks were disconnected, two people 
 could at least partially scrub the compartment 
 for four. The other two could take absorbent 
 and fold it up in any piece of cloth and breathe 
 through it. Emergency CO2 absorbent stored in 
 the diver compartment should last two days. 
 
 2. Controlled Flooding (leaks) - the following type 
 leaks might occur anytime at any depth: 
 
 a. Minor leaks due to "0" ring failure or corrosion 
 around mechanical, electrical, and pipe hull 
 penetration. 
 
 b. External depth gage leaks due to gage failure. 
 
 c. Pneumatic lines leaks allowing water to back-up 
 line into J-S-L compartment. 
 
 d. Electrical penetrator burn out. 
 
 2-4 
 
Any one of the above is cause to abort a mission. 
 Surface as soon as possible. Pressurization of 
 the sphere to control these leaks should not be 
 done except when on the surface. The sphere hatch 
 will. only hold 60 PSI of internal differential 
 pressure. Electrical equipment should be secured 
 as necessary to eliminate short circuits. 
 
 F ire 
 
 1. The most probable cause of a fire in the J-S-L 
 will be an overloaded circuit due to a ground or 
 
 a faulty electronic component. Prior to the fire, 
 the submersible occupants are likely to detect an 
 odor of smoldering insulation and/or possibly see 
 smoke. Just prior to this or maybe simultaneously, 
 the occupants should note the failure of a piece of 
 equipment. The second most probable cause of a 
 fire would be due to auto-ignition in one of the 
 pneumatic systems. Because fire cannot be entirely 
 ruled out, oxygen should be carefully monitored to 
 eliminate concentration above twenty-one percent. 
 The lowest concentration of oxygen capable of 
 supporting life wihout any ill effects is 16 percent. 
 
 2. Smoke and/or fire while cruising: 
 
 a. In the sphere 
 
 (1) Turn off circuit breakers. 
 
 C2) Turn off sphere O2 flow. 
 
 (3) Don emergency regulators and face masks. 
 
 (4) Fight fire with extinguisher and/or water. 
 
 (5) Commence surfacing. 
 
 (6) Inform the support ship and diver compartment. 
 
 (7) Upon reaching the surface, ventilate with 
 HeC>2; through the flare gun barrel as necessary 
 
 b. In the diver compartment 
 
 (1) Secure the 2 bleed. 
 
 (2) Inform the sphere. 
 
 (3) Don emergency rebreather or masks, or 
 Kirby Morgan masks. 
 
 2-5 
 
(4) Fight fire with extinguishers and/or water. 
 
 (5). Sphere: 
 
 Ca) Secure diver power and oxygen to 
 the diver compartment. 
 
 (b) Commence surfacing. 
 
 (c) Inform the support ship. 
 
 (d) When the J-S-L reaches the surface, 
 have the divers ventilate the diver 
 compartment with He02 . 
 
 3. Smoke and/or fire while a diver is locked-out: 
 
 a. In the sphere 
 
 (1) Secure the oxygen bleed. 
 
 (2) Call the diver back. 
 
 (3) Turn off circuit breakers. 
 
 (4) Don emergency regulators and face masks. 
 
 (5) Fight fire with extinguishers and/or water. 
 
 (6) Man the sound-powered phcfne. 
 
 (7) Commence surfacing as soon as the diver 
 compartment is over pressurized. 
 
 (8) Inform the support ship if possible. 
 
 (9) Upon reaching the surface, ventilate with 
 HeC>2 through the flare gun barrel . 
 
 b. In the diver compartment 
 
 (1) Inform the sphere. 
 
 (2) Don emergency rebreather or spare Kirby 
 Morgan mask and enter the water in the manway 
 
 (3) Fight the fire with water or extinguisher. 
 
 (4) Blow down with He02- 
 
 (5) Sphere: 
 
 (a) Alert the diver in the water. 
 
 (b) Secure oxygen to diver compartment. 
 
 2-6 
 
(c) Inform the support ship. 
 
 (d) As soon as the smoke is cleared, 
 get the divers back inside and 
 commence surfacing. 
 
 Ruptured Pressure Line 
 
 1. Internal - A ruptured pressure line or leaking 
 fitting on any one of the pneumatic systems 
 inside the submersible can easily be detected by 
 the sudden change in the noise level and/or the 
 increase in compartment pressure. A leak in the 
 oxygen system can also be detected by monitoring 
 the PO2 meters. The faulty system should be iso- 
 lated immediately by securing the appropriate hull 
 stop valve. In most cases, it will be possible 
 to bypass or repair the malfunction while submerged. 
 A report should be passed to the support ship. 
 
 a. Ballast tank pressurization lines - A ruptured 
 or leaking ballast tank pressurization line 
 would be detected by observing bubbles while 
 pressurizing the ballast tank. Since the 
 variable ballast tanks have a common pressuri- 
 zation line, a break in this line would disable 
 both. All other ballast tanks have separate 
 pressurization lines and a broken line can easily 
 be isolated by securing the appropriate blow 
 valve. The main ballast tanks also can be pressur- 
 ized from the diver compartment. The mission 
 should normally be aborted and the pilot should 
 request permission to surface as soon as practicable 
 after detecting a faulty ballast tank pressurization 
 line . 
 
 b. Gas supply lines - A rupture in one of the gas 
 supply lines. will be detected by loss of pressure 
 on the appropriate gage and/or bubbles in the water. 
 In the event a gas supply line is broken, secure 
 the appropriate hull stop valve and realign valves 
 as necessary to keep the J-S-L operational. Request 
 permission to surface as soon as practicable. 
 
 Entrapment 
 
 Your best insurance for survival in case of entrap- 
 ment is the pre-mission planning and the thoroughness 
 with which the pre-launch check was made; one item 
 overlooked could make the difference between life and 
 death. 
 
 2-7 
 
2. Entrapment of J-S-L means that it is being 
 physically held in place, such as getting 
 caught in a crevasse, being stuck in the mud, 
 entangled in plant life, or entangled in sub- 
 merged debris, such as cables or fishnets. More 
 than likely, the J-S-L could be worked out of 
 all these situations by using the thrusters and 
 blowing all ballast tanks, except entanglement 
 in submerged debris . 
 
 3. As long as either the diver compartment or pilot's 
 sphere is dry, the J-S-L has enough positive 
 buoyancy to surface if it is not anchored to the 
 bottom in some way. If, by chance, the diver 
 compartment was flooded, the battery pod would 
 have to be dropped and the main ballast tanks 
 blown to gain enough positive buoyancy to surface. 
 
 4. If the J-S-L is entrapped and cannot break loose 
 by normal means, and neither the pilot or divers 
 can clearly determine that a lock-out diver could 
 free the submersible, the J-S-L would blow the 
 buoy, vent its tanks, secure all unnecessary equip- 
 ment to conserve power, and await rescue. A lock- 
 out dive would be conducted only as a last resort 
 in the event that the divers were unable to clear 
 the obstruction. 
 
 5. If the divers are unable to free the J-S-L, bring 
 them back in and shut both "A" and "B" hatches. 
 
 Do not over pressurize. Keep calm, conserve power, 
 monitor your PO? and PCO2 meters, and maintain com- 
 munication on the sound-powered phone . 
 
 NOTE: Anytime the J-S-L is launched, it has 
 gas onboard for a lock-out to maximum 
 mission depth plus adequate dive gear 
 and rescue tools aboard. There is 
 always at least one qualified J-S-L 
 lock-out diver in the diver compartment.

 PRIMARY LIFE SUPPORT EQUIPMENT 
 
 1. Beckman CO2 Analyzer (see Reference 1) 
 
 2. Lindbergh Hammar Scrubber 
 
 Sodasorb is used in these units and can either be filled within the 
 chamber or a fresh canister can be sent in via the medical lock. 
 See Reference 2 for further information on the performance. 
 
 3. Bio Marine O2 Analyzer Recorder 
 
 This unit will simultaneously measure the PO2 in the main lock and 
 entrance lock as well as the ship's lazarette and control console. 
 Rustrak recorders continuously operate for the main lock and entrance 
 lock only. The chamber stations read from 0-2.0 ATM of O2 and 
 the lazarette and control console stations read from - 0.4 ATM of 2 
 For further information, see Reference 3. 
 
 4. Pyrotector Automated Fire Suppression System 
 
 This integral system utilizes He! on 1301 in the control console and 
 lazarette and water' with a helium pressure head for the main lock 
 and entrance lock. Operation of the system is either manual or 
 automatic utilizing numerous infra-red sensors to activate the 
 system. For further information on this system, see Reference 4. 
 
 2-10 
 

 5. Helle Communications 
 
 This system provides communication via speakers to the main lock 
 and entrance lock. To date no provisions have been made for helium 
 voice unscrambling. Communications are continuously open from the 
 chambers to the control console. 
 
 6. Lighting via External Source 
 
 Light to the main lock and entrance lock is provided via J. M. Canty 
 Associates rheostated lights mounted externally. Light enters the 
 chambers via plexiglass penetrators. 
 
 7. Remote Temperature Probe 
 
 Continuous monitoring of the temperature in the main lock in degrees 
 F is shown in the control console on a Weksler Instrument Gauge. 
 
 8. Scott Breathing Regulators with Overboard Dump 
 
 There are two regulators in the main lock and one regulator in the 
 entrance lock. All regulators have a first stage regulator mounted 
 internally to provide 125 psi over ambient to the divers. All 
 masks are also equipped with a vacuum regulator so that divers 
 may use them as emergency breathing regulators at any depth. 
 These same masks provide either air, mix-gas or oxygen to the 
 divers upon demand. 
 
 BACK-UP EQUIPMENT 
 
 1. Bio Marine Hand-Held O2 Analyzers 
 
 Three model 255 Bio Marine O2 Analyzers are available in the control

 Genera! Description 
 
 Designed for the rugged hyperbaric environments of 
 c/ivihg. clinical, and research chambers, the MINOS 
 ACDM (Atmospheric Carbon Dioxide Monitor) will 
 faithfully safeguard your breathing environment by 
 measuring carbon dioxide content from 0.1 through 
 30 millimeters of mercury partial pressure. Although 
 the availability of oxygen at safe levels in a sealed 
 chamber is critical, the build-up of carbon dioxide 
 must also be monitored carefully. The MINOS ACDM 
 helps to make certain that personnel inside chambers 
 are not exposed to dangerous levels of carbon diox- 
 ide. The MINOS ACDM — together with its companion 
 MINOS AOM (Atmospheric Oxygen Monitor) — offers 
 you a complete atmospheric monitoring system. 
 
 Superior Design Sensing System 
 This self-contained system responds directly to the 
 partial pressure of carbon dioxide, independent of 
 total sample pressure. Operating electro-chemically, 
 the sensor contains a pH electrode and a reference 
 electrode. Separated from the atmosphere by a mem- 
 brane permeable to carbon dioxide, the electrolyte 
 pH will change as a function of exposure to carbon 
 dioxide. Electrode potential is proportional Jo a loga- 
 rithm of the partial pressure of carbon dioxide in the 
 sample. The partial pressure of carbon dioxide is 
 displayed on a logarithmic meter scale on the instru- 
 ment. The ACDM may be ordered for either panel or 
 bulkhead mounting. 
 
 
 The rechargeable sensor will operate up to 30 days 
 before recharging is necessary. Since the sensor re- 
 ceptacle contains a preamplifier, the sensor can be 
 used at considerable distances from the meter, with 
 no signal degradation from cable noise; or, if desired, 
 the sensor-receptacle assembly is easilv rsounled 
 directly on the face of the ip«»njTM»nt. fne ACUM 
 functions in oper-.-rvj ^.'ebsures as high as 35 abso- 
 lute atmospheres, making it ideal for almost any 
 application from ambient to hyperbaric pressure. 
 
 Features 
 
 • Uses-alkaline batteries or 12 to 32 VDC external 
 power (some options require 14 to 32 VDC external 
 power). 
 
 • External outputs available for gemote alarms, 
 meters, recorders, or an analog-to-digital converter. 
 
 Complete Monitoring Systems 
 By using the MINOS ACDM in conjunction with the 
 MINOS AOM (Atmospheric Oxygen Monitor), z 
 complete atmosphere monitoring system is estab- 
 lished. Ask for BulletinJD-2016 for information on the 
 MINOS AOM.

 Roasnr a. bake,-* (,PUEA 787M 'CAKBON DIOXIDE REMOVAL SYSTEM'S « ^ « " 
 
 Units in this series are assembled from three main components* 
 an outer sealed case,* a refillable dessicant canister, and 
 a power unit. The canister and power unit are mounted in 
 tandem -within the exterior case. In operation the turbine 
 end of the power unit, exhausts air from inside the case } 
 forcing it out through coaxial ducting ■ surrounding the power, 
 unit. As the gas within the case is exhausted, a pressure 
 differential is established, causing external- air to flow 
 through the intake end of the dessicant canister. This air 
 is scrubbed or purified by chemical compounds -which retrieve 
 and retain carbon dioxide, and pass other gases in the 
 breathing mixture to be reused indefinitely. 
 
 Operating electric motors of any type in environments with 
 high partial pressures of oxygen or flammable gases is 
 extremely hazardous. Commutator- type motors with sparking 
 brushes are obviously dangerous. Induction motors, though 
 brushless, are also dangerous since short circuits can 
 develop in field and rotor coils to trigger an explosion. 
 Inverter-type motors share the same deficiencies. 
 
 The PUHA 787M completely isolates the motor, wiring system 
 and other electrical components from contact with the 
 environmental atmosphere by installing these inside a heavy 
 walled pressure vessel. To eliminate the danger of seal 
 wear on a rotating motor shaft, a magnetic coupling connects 
 the motor with the external dual turbine. There is no direc-fc 
 mechanical connection between motor and turbine j magnetic 
 lines of force pass through solid stainless steel, estab- 
 lishing a high torque interlock. All dynamic sealing is 
 eliminated. Other static sealed closures are dual sealed 
 with two types of O-ring glands for safety. Each unit- is 
 environmentally leak checked at pressure stages from 1 to 
 1500 PSIG and certified. 
 
 Motor . heat is dissipated through a heat sink system. There 
 is no direct air flow through the motor 
 
 All bearings in contact with high pressure environmental oxygen 
 are specially treated and compatible with any breathing mix- 
 tures.

ELECTRICAL CONNECTION - 7S7M9 Series scrubbers operate on 24 
 to 60 volts, AC or DC. The motor is a universal type and is 
 uni-directional; it cannot be externally reversed by inter- 
 changing;' leads. Connect two wires from hull penetrator to a 
 suitable power source. Make certain that all connections arc 
 mechanically tight. Tie do\>m all loose cable with suitable 
 straps or clamps to guard against accidental snagging. Use_

 GROUND TERMINAL - Secure a heavy gauge wire to the ground ter- 
 minal (located at the exhaust end of the unit next to the hull 
 penetrator) and connect it to an adequate ground; (metal side- 
 wall of a' hyperbaric chamber). CONNECT GROUND CABLE BEFORE

 MOUNTING- Scrubbers will operate in any attitude. Preferred 
 mounting position is vertical', against a sidewall near 'floor 
 level. (See Loading) Any holes drilled and tapped into the 
 scrubher end plates for mounting purposes should be sealed 
 gas— tight with RTV* Silicone Cement. (See Punctures) Special 
 mounting brackets are available' from the factory. 
 
 SNAP-LOCKS - The quick-release hooks securing the loading cover 
 penetrate the case through 0-ring gland fittings and 'arc gas- 
 tight. Apply a drop of APPROVED SILICONE 0IL\tp each rod to 
 keep it operating smoothly. (See Lubrication and Loading) 
 
 FITTINGS and HARDWARE - All stock fittings have been tested 
 and certi f ied . • Do not endanger safety and certification by 
 changing or altering installed fittings. If modifications are 
 required, return to factory for refitting, testing and certi- 
 fication. (See Maintenance) . DO NOT DRILL, TAP V/ELD, OR IN 
 ANY WAY ALTER THE. PRESSURE HOUSING. 
 
 ABSORBENT - Any approved carbon dioxide absorbent ma : y be used, 
 including plastic prepacks .(disposable type). Prepacks are 
 NOT recommended in high partial-pressure oxygen atmospheres 
 because of their fl amenability. Gas flow through prepacks is 
 not as efficient as through stock stainless steel refillable 
 canister. (See Loading and Baralyme/Sodasorh : pH) 
 
 COp REMOVAL - Gas exchange rate is controlled directly by 
 varying input voltage. Unit can be ideally matched to any 
 system by monitoring C0 2 level and altering the supplied volt- 
 age. In large . hyperbaric installations, multiple scrubbers 
 may be used to hold C0 2 concentration at the required level. 
 (See excerpts - test reports) 
 
 PAINT - Use only fire-resistant , oxygen-compatible epoxy coat- 
 ings when retouching any surface.

LOADING - The unit is prepared for use by filling the desic- 
 cant canister with a carbon dioxide absorbent chemical. Fill 
 ' "p r± orTtTS ach /use" with f re shy dry de sic'cant... .— PPJ^OTL Qmttj-m s 
 procedure. Sodasorb is recommended, although the canister may 
 be charged with any approved desiccant. 
 
 Remove the canister from- within the case by twisting the five 
 scjruring^snap^loclcs to^release the loading cover. Remove the 
 
 ""cover, 'expo'sin^j^lfe^canisoer. Lift the canister.^jstraight^au.t;* 
 with the wire bail and then free the canister top from the 
 
 • three locking bayonet pins. Fill the cylinder carefully with 
 desiccant. ' While filling, tap the canister firmly on *th e 
 bottom with the palm of the hand to settle the granular chem- 
 ical. If the unit is operated in a vertical position, the 
 desiccant will settle, firmly without "channeling." If oper- 
 ated in a horizontal attitude, "the canister must* be packed 
 tightly Avith great care to avoid settling which might cause a 
 void along the side of the cylinder through which, intake gas 
 would flow freely without passing through the desiccant. Such 
 channeling is extremely dangerous since the carbon dioxide is 
 not retained. 
 
 Inspect the bottom gasket (intake end) on which the canister 
 seats £ or dirt or dust and clean carefully. Clean the mating 
 machined bronze surface of the canister. Replace the top screen 
 canister cover, locking it in place on the bayonet pins. Lower 
 the canister into position within the unit. 
 
 Clean the top machined surface of the exterior case around the- 
 five snap-locks. Check the loading cover gasket for- dust and 
 wipe clean. Position the loading cover over, the snap-lr»c!:s , 
 and push it straight down, forcing the attached bronzp compres- 
 sion ring against the canister. Pull up on the snap -locks 'with 
 a slight outward force and twist them into position to lock 
 the cover securely in place. 
 
 Check the loading cover gasket carefully for proper positioning , 
 especially along its straight edge where the actual sealing 
 area is narrow. ' It 'is important that the exterior case is 
 maintained gas tight, so that the air flow is through the 
 desiccant canister only. If the case -is punctured, patch 
 immediately or carbon dioxide removal will be severely impaired 
 (See Maintenance).

 OPERATION INSTRUCTIONS 
 FOR 
 REMOTE OXYGEN MONITOR AND RECORDER 
 (DEVELOPED FOR THE HARBOR BRANCH FOUNDATION) 
 
 GENERAL 
 
 This monitor was developed to fill a need for a four (4) station 
 hyperbaric oxygen analyzer with adjustable high and low alarms. Integrated 
 circuit techniques have been employed in its construction, insuring many 
 years of reliable service, while enabling a complexity impossible just a 
 few years ago. The unit will operate over a wide temperature range (32° F 
 to 105° F) and will enable the operator to maintain precise control over the 
 oxygen partial pressure in the diver decompression chamber. 
 DESCRIPTION AND CONTROLS 
 
 This monitor consists of a four (4) station oxygen monitor with adjustable 
 high and low alarms in a brushed aluminum rack configuration. In addition, 
 stations £l & 52 are backed up by Rustrak t ype re< , n ^ a, '« , - , L these recorders 
 produce a permanent record of the oxygen level for later evaluation. Stations 
 vl & v2 have a full scale sensitivity of 2 Atm. Abs. Stations 03 & £4 have 
 a full scale sensitivity of .4 Arm. Abs. Each station has a sensor select 
 switch, sensor calibrate controls, alarm adjust switch, high and low alarm 
 set controls, recessed taut band suspension display and an alarm light emiting 
 dicde. In addition, common to all stations, the front panel contains a power 
 disconnect switch, an audio alarm disconnect switch, a sonalert type audio 
 alarm and push to reset circuit breakers for batteries and line. All stations 
 share a common power supply with a battery back up.

 DESCRIPTION 
 
 1.1 INTRODUCTION 
 
 This technical manual provides information on the Optical Fire 
 Detection and Extinguishing System Components manufactured by 
 Pyrotector, Incorporated, Hingham, Massachusetts for installation 
 in HSF's shipboard decompression facility. 
 
 .1.2 GENERAL DESCRIPTION 
 
 The Fire Detection and Extinguishing System is an integrated 
 automatic detection, warning and extinguishing system utilizing 
 high speed optical detectors, signal conditioning amplifiers, 
 control panel and Hal on 1301 extinguisher assemblies which can 
 be activated at the control panel by operation of electrical 
 switches or manually at the site of the solenoid valve assembly. 
 Remote manual operation may be incorporated by the addition of 
 pull cables connected to the manual override lever on the 
 solenoid valve assembly. 
 
 Independent detection and extinguishing is provided for the lazarette, 
 control console area and D.D.C. A separate control amplifier is 
 mounted in or adjacent to each compartment to accept detector 
 signal inputs and to relay alarm output to the control panel. 
 
 Pressure Switches are installed in each Compartment. They turn 
 on an amber light on the control panel and are activated by the 
 pressure rise in the extinguishing agent distribution piping 
 when the system is discharged. 
 
 Audible alarms (Horns) are located in the D.D.C. control console 
 to warn of a fire in any compartment and -in the control console 
 to warn of a fire in that compartment. 
 
 A test switch is provided on the electrical control panel for 
 verifying system integrity and operation of the detection components. 
 Components of the system are designed to operate from a nominal 
 28 VDC. Compartments protected by the system and allocation of 
 components are listed in Tabele 1-1. Descriptions and illustrations 
 of components are provided in Figures 1-1 through 1-10.

 Tha Model 900 provides continuous monitoring of both com- 
 bustible gas and oxygen in any environment for a full week 
 (40 hours) between battery recharges. Audible and visual 
 alarms automatically warn of the presence of combustible gas, 
 oxygen deficiency or low battery voltage. 
 
 The combustible g3s sensor employs an advanced ceramatized 
 gas sensing element insuring long life. The proven BMI galvan- 
 ic oxygen sensor is self-powered and never requires rebuilding 
 or recharging. The 900 is fully temperature compensated from 
 5°F to 1 10°F and meets U.S. Bureau of Mines intrinsic safety 
 requirements. 
 
 The 900 may also be used in spot checking for both oxygen 
 and combustible gas at the press of a button. 
 
 Each unit comes with a remote sampling kit. The unit is 
 housed in a rugged leather carrying case and may be worn on 
 the belt or on the shoulder. The 900 is completely solid state 
 with no moving parts to wear out. A loud., penetrating remote 
 alarm is available to provide additional warning of alarm con- 
 ations to outside or "topside" personnel. 
 
 . ne 900 is particularly useful in mines, tunnels, silos, tanks, 
 ship holds, railroad tank cars, manholes, sewers and other lo- 
 cations in the chemical, petroleum, mining, utilities and ship- 
 ping industries where combustible gases and oxygen deficien- 
 cies may be found.

Notification of Coast Guard and Navy Rescue Organizations 
 
 Prior to commencement of the at-sea portion of the project, Harbor Branch 
 Foundation, Inc. shall notify the Coast Guard in accordance with Coast 
 Guard Notice 3130, by completing and submitting USCG Form 4790 (8-71), 
 "Summary of Planned Submersible Operations." This form will be sent to 
 Commander, 8th Coast Guard District, New Orleans. The Commander of the 8th 
 Coast Guard District will notify appropriate Navy authorities of the impending 
 operation, and will issue a warning to mariners giving location and time of 
 operations in order to minimize interferences during the operations. 
 
 If the submersible should be unable to surface, the support ship shall radio 
 a MAYDAY message to the Coast Guard on 2182 KHZ, and other emergency circuits 
 as may be available. The Coast Guard Rescue Coordination Center (New Orleans) 
 may be reached using a telephone call via the marine operator 504/589-6225. 
 
 Upon receipt of the MAYDAY message, the Coast Guard will proceed in accordance 
 with Commandant Instruction 3130. 7A of 5 December 1975. If Navy assistance is 
 appropriate, the Coast Guard will so request by calling the Navy Department 
 Duty Captain at 202/695-0231. The Navy Duty Captain will take action in 
 accordance with 0PNAV Instruction 3130.4A of 29 October 1973. Applicable portions 
 of Coast Guard Instruction 3130. 7D and 0PNAV Instruction 3130. 4A are presented

 Subj : Operations Involving Civilian Submersibles 
 
 1. Purpose . This Instruction provides procedures Co be followed by 
 the Coast Guard with respect to operations involving civilian submer- 
 sibles. 
 
 2. Cancellation . Commandant Instruction 3130, 7C CH-1 is cancelled. 
 
 3. Discussion . 
 
 a. The Coast Guard's search and rescue responsibilities extend 
 to vessels operating under, as well as .on, the surface of the sea. 
 These responsibilities therefore include the small number of civilian 
 submersibles which operate in or near U.S. waters on scientific, indus- 
 trial or other missions. The safety record of these submersibles has 
 been good, but the few accidents have demonstrated both the difficulty 
 of rescue and the potential for public interest. The Coast Guard has 
 no special undersea search and rescue equipment to assist a submersible 
 unable to surface and must discharge its responsibility by requesting 
 suitable equipment be brought to the scene. Equipment is available 
 which could effect a rescue in most situations, but frequently information 
 on the location and status of the equipment is not available. The 
 primary source of expertise and equipment is the U.S. Navy, and procedures 
 have been established to permit utilisation of Navy resources in the event 
 of a civilian submersible SAR incident. A single point of contact has 
 been established, as the Navy can provide not only fleet resources but 
 specialized experimental equipment located at laboratories, and also 
 civilian specialists retained on contract for undersea salvage. The, 
 point of contact is the Navy Department Duty Captain at the Pentagon, 
 as described in OPNAVINST 3130.4, enclosure (1) . When the Navy has responded 
 and assumed the role of SAP. Mission Coordinator, the Coast Guard role be- 
 comes one of support. Until that time the Coast Guard must respond 
 with its own resources and whatever local civilian or government help 
 is available. 
 
 b. Submersible operations present another problem. This is one of 
 interference with Navy operations. To enable the Navy to reduce this 
 possibility, to reduce the chance of classifying a civilian submersible 
 as an unknown submerged vessel necessitating investigation, and to aid 
 in prompt SAR assistance the Commandant has established a voluntary 
 
 3-2 
 
COMDTINST 3130, 7D 
 
 5 DEC 1975 
 
 reporting system through, which 'pertinent information can be relayed to 
 concerned parties. The Commandant (G-M-2/USP/83) monitors submersible 
 activity and advises known submersible operators of the reporting system 
 and the procedure for requesting assistance if needed. 
 
 c. There is no mutual assistance plan, formal or informal, in 
 effect among the submersible operators. Most operators, however, could 
 be expected to be willing to assist in the rescue of a distressed sub- 
 mersible. 
 
 4. Action . 
 
 a. Commandant (G-M-2/USP/83) 
 
 (1) Inform all known submersible operators and owners in the 
 United States of the voluntary reporting system. Enclosure (2) is a 
 copy of the notice used for this purpose. 
 
 (2) Maintain liaison with the Navy and other organizations 
 to provide coordinated planning for submersible emergencies. 
 
 (3) Distribute periodic reports on the status of U.S. sub- 
 merslbles to all District Commanders. Coordinate the distribution 
 of appropriate informational material to District Commanders (RCC's). 
 The following publications are currently distributed automatically: 
 
 Deep Submergence Systems Surrr'ary and Characteristics 
 Manual: Published and revised annually by Commander Submarine Develop- 
 ment Group One as C0MSU3DEVGRU ONE INSTRUCTION 5450.1 and contains 
 characteristics of U.S. military and civilian submersihles , unmanned 
 undersea systems, and habitats. 
 
 An Inventory of Navy Laboratory R&D Equipment Available 
 for Emergency Undersea Operations : Published by and revised annually by 
 Naval Undersea Center, San Diego as NUC AP-2. 
 
 b. District Commanders 
 
 (1) On receipt of information on planned submersible operations 
 disseminate this information by message as described in enclosure (3) . 
 Issue a Notice to Mariners as appropriate giving the location and time(s) 
 of operations to minimize interference during the operations. 
 
 (2) In the event that a specific request for assistance to a 
 civilian submersible is received:

 If appropriate request implementation of SU3MISS/SU3SUNK fcr civilian 
 submersibles in accordance with OPNAV INSTRUCTION 3130.4, and the USN 
 ADDENDUM to NTT? 37(B). Send a follow-up message in the format of enclosure 
 (4) to confirm the request. 
 
 (b) Respond with appropriate Coast Guard resources, such as On- 
 Scene Commander rescue platform (buoy tender), traffic control, communi- 
 cations, and logistics. 
 
 (c) Ascertain if there are any other- civilian submersibles 
 available; request that they assist the ais tressed sub. 
 
 (d) Coordinate the response as SAR Mission Coordinator (SMC) 
 until the Navy assumes this responsibility. Continue to provide any 
 assistance requested after the Navy assumes SMC. Ensure that the AREA 
 COMMANDER and the COMMANDANT are kept informed of the progress of the 
 rescue both before and after the Navy assumes SMC. 
 
 (e) Until the Navy assumes SMC (and in case the Navy is unable 
 to assume SMC) obtain advice from Headquarters Flag Plot and make. use 
 of best available military and civilian resources. A brief guide to 
 RCC controllers in handling submersible SAR incidents is printed by 
 and available from the National Search and Rescue School, Governors 
 Island, New York. 
 
 (f) Prepare a SAR Case Study in. addition to the normal assistance 
 report. 
 
 5. Availability of Forms . 
 
 a. Commandant (G-M-2/USP/83) shall distribute the SUMMARY OF PLANNED

 1# Purpose . The purpose of this bill is to ensure that the 
 Navy Department is alerted to provide assistance whenever a 
 SUBMISS/SUBSUNK is executed for a manned non-combatant sub- 
 mersible. 
 
 2. Cancellation . OPNAV Instruction 3130.4 dated 18 July (A 
 1969 is hereby superseded. 
 
 3. Scope . This bill serves to advise the Navy Department £R 
 duty captain, Navy Command and Support Center (NCSC) of the 
 following: 
 
 a. Action to be taken by him to alert the Navy Depart- 
 ment or initiate appropriate U. S. Navy action if required.

 requirements of national defense, rescue facilities for the 
 promotion of safety on, under and over the high seas and 
 waters subject to the jurisdiction of the United States. 
 The Coast Guard has issued an instruction on civilian sub- 
 mersible operations, Commandant Instruction 3130.7 series. 
 The Navy is assigned no direct responsibility in the N'atior 
 SAH Plan for the rescue of personnel or salvage of civiliar 
 owned and operated submersibles . However, provision is mac 
 for the use of Navy facilities to meet civil needs on a bas 
 of non- interference with higher priority military missions 
 If Navy assistance is requested by the Coast Guard, "Event 
 SUBMISS/SUBSUNK" may be placed in effect by the duty capta: 
 aftcr consultation with the appropriate fleet commander anc 
 the Deputy Chief of Naval Operations (Submarine Warfare) . 
 If "Event SUBMISS/SUBSUNK" is declared, the Navy- will respc 
 to the fullest extent possible within its existing capabil:

 area or district commander will designate the senior U. S. 
 Navy officer on scene as the on-scene commander. That off 
 shall be qualified for succession to command at sea, and i 
 practicable, will be a submarine officer serving in a sub- 
 marine billet. 
 
 c. The provisions of this instruction will cease to 
 apply should the operation become simply one of a salvage 
 nature. Appropriate salvage instructions will then apply. 
 This could occur should: 
 
 (1) The personnel in the disabled vehicle escape o 
 be rescued and the submersible or parts thereof remain on 
 the bottom. 
 
 (2) The personnel entrapped have exhausted their 
 life support and rescue is no longer possible. . .

 1. Upon receipt of information that a manned non-combatant (R 
 submersible SUBMISS/SUBSUNK event has been executed, the 
 
 duty captain will notify the persons and activities listed 
 on the notification list (enclosure CI)) using the most 
 expeditious means available. 
 
 2. Upon receipt of a request for Naval assistance from a (R 
 cognizant Coast Guard area or district commander in the 
 
 event of the loss of a civilian submersible, the duty 
 captain initiates event SUBMISS/SUBSUNK, designating the 
 appropriate fleet commander in chief to take the necessary 
 action and authorizing direct liaison with the cognizant 
 Coast Guard commander. He will notify the persons and 
 activities listed in the notification list that SUBMISS/ 
 SUBSUNK has been placed in effect. 
 
 3. The Director, Fleet Operations, Readiness, Navy Command (R

 During a mission the main circuit breakers may trip due 
 to an overload. When this happens ail equipment should 
 be de-energized and the breakers reset. Then energize 
 the equipment again, one piece at a. time, to attempt 
 to establish the cause. If the breakers continue to 
 trip and the cause cannot be isolated, surface with 
 caution as soon as practicable.

 GE NERAL INF ORMATION REGARDING 
 NtAgggg NON -COMBATANT SUBMSkSIBLES 
 
 1. Deep submersibles are generally designed to perform 
 specific ocean engineering tasks. As a result, the size, 
 hull form and equipment arrangements are usually quite 
 different. 
 
 2. Deep submersibles have the following common character- (R 
 istics : 
 
 a. Life support systems capacity varies and is gen- 
 erally less than -24 hours. Some exceptions are the 
 Submarine NR-1 and USS. DOLPHIN. 
 
 b. The hatches on the deep submersibles are normally 
 not compatible with the Deep Submergence Rescue Vehicles 
 (DSRVs) and Submarine Rescue Chambers (SRCs) used for 
 submarine rescue. 
 
 c. Deep submersibles are usually not designed for 
 escape using buoyant ascent. Again the deep diving sub- 
 marines USS DOLPHIN and Submarine NR-1 are exceptions. 
 
 d. At the present time the only feasible method of 
 saving the lives of an untethered manned non-combatant 
 deep submersible crew would be to salvage the vessel. 
 
 3-13 Enclosure (3) 
 
4. If the J-S-L I is entrapped and cannot gain it's 
 freedom by blowing all ballast and thrustcring, 
 time should not be wasted waiting on help from 
 the surface. Turn off all unnecessary electrical 
 equipment to conserve power for your scrubbers 
 and communications. Vent off ballast tank, blow 
 down and diver compartment and lock-out a diver 
 to survey the situation. Once you know what 
 your problem is you can figure a way out. This 
 information will be invaluable to the people on 
 the surface preparing for your rescue. Be sure 
 to keep accurate records on- the divers' depth 
 
 and time. Keep the support ship informed of all 
 measures taken. 
 
 5. In the event that J-S-L I divers are unable to 
 free the J-S-L I, bring them back in and shut 
 both "A" and "B" hatches. Do not over pressurize. 
 Release your emergency location buoy,, keep calm, 
 conserve power, monitor your PO2 and ?C02 meters, 
 and maintain communication on the sound powered 
 phone . 
 
 NOTE ? Anytime the J-S-L I is launched it has gas 
 
 onboard for a lock-out to maximum mission 
 
 depth plus adequate dive gear and rescue tools 
 
 aboard. There is always at least one 
 
 qualified J-S-L I lock-out diver in 'the 
 
 diver compartment .

that contains a quart of m iner al oil. .as a lubricant 
 and has been deflated with a vacuum DumD, rolled 
 up and tied into the aluminum funnel. This funnel 
 also acts as a receptacle for the surface rescue 
 drop-lock. The float is equipped with, a 2 PSI 
 relief valve. High pressure air is piped up from 
 the pilot's sphere- to a special adaptor that is 
 attached to the funnel and the float. When the float 
 is pressurized from the sphere it expands and breaks 
 away from the funnel and air connection. Fully 
 inflated, the buoy has 281 pounds of positive buoyancy 
 which overcomes the tension on the reel of the cable 
 and streams it to the surface. 
 Rescue 
 
 Submersible rescue can be accomplished by dropping 
 a specially designed drop-lock down the buoy line. 
 The drop-lock is grooved on one side so the unit 
 fits around the buoy line. The end is attached to 
 1500 ft. of rescue cable. The rescue winch is 
 located on the submersible ' s support. vessel .
