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 obse-rving 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.

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

pl ants 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 lock-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.

III. MISSION PLAN

PHASE II:

10-14 Sept. 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.

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 diagrammatically 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

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 Director - 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.

2. J-S-L Handling System for R/V 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/V JOHNSON has aluminum

pipe back stops with gates that can be moved through 900 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.

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.

b. Breathing Mixture Air
1200 cubic feet total-air
600 cubic feet total-02

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.

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 V-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.

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
Ncompression chamber aboard the
R JO NSON.

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 thecapability 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.

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

The Straza pinger is mounted in a bracket on the after "A" frame

and is turned on by a saltwater activated switch. The Helle pingeris

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.

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.

Roger W. Cook RFD 1, Box 196
Operations Director Fort Pierce, Florida 33450
Harbor Branch Foundation, Inc. 305/465-2400

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 submersihle 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
,liver 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
support vessel for the PTB. He piloted 41 dives in the PTB. Since
January of 1974, he has been with Harbor Branch Foundation, Inc.,
a not-for-profii-corporation engaged in pollution studies, ocean science
and engineering research and development. As.Operations Director, he
is repsonsible for planning and directing the missions of the founda-
tion's research vessels, submersible support ships, and the J-S-L I and
II, Harbor Branch's aluminum and acrylic submersibles. Through his
supervision and training for the 4-man crafts, these submersibles are
used for diver lock-out which serve the marine scientists at Harbor
Branch with the capability to observe, collect living samples, photo-
graph, chart and.measure features and phenomena of the undersea en-
vironment heretofore not possible for surface oceanographic ships.
Mr. Cook has directed more than 100 scientific cruises thus far at Harbor
Branch', the most recent being a, 600' lock-out dive off the coast of Fort
Pierce, Florida, the second deepest-on record from a submersible. The ,
record lock-out dive, 700 feet, was performed by him from the Perry-Link
DEEP DIVER In 1968. He also made the world's deepest salvage dive at 510-
feet and deepest aircraft recovery in freshwater at 440 feet. He has
personally logged over 100 bell dives.

APPENDIX 2

J-S-L- Emergency.Procedures,
DDC Facility and Life Support Systems

J-S-L Emergency Procedures

Communications

1. If voice communications are lost on the underwater
telephone for fifteen minutes, the J-S-L pilot
should su--face 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 I-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".

2-1

Flooding

1. Uncontrollable - It i s 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 o,--less, but the J-S-L could surface on the
other tanx ,nd if necessary, the battery pod could @,e
dropped. Themost 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 oft 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 @qater'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

I
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,
C02 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 C02 absorbent stored in
the diver compartment should last two days.

2. Controlled Flooding (leaks) - the following type
leaks mrght 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.

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.

Fire

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.

(2) Turn off sphere 02 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
He02; through the flare gun barrel as necessary.

In the diver compartment

(1) Secure the 02 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.

(51 Sphere:

(a) Secure diver power and oxygen to
the diver compartment.

(b) Commence surfacing.

(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.

(21 Call the diver back.

(3) Turn off circuit breakers.
(4) Don emergency regulators an'd face masks.

(5) Fight fire with extinguishers and/or water.
(6) Man the sound-powered ph(@ne.

(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
He02 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 HeOi.

(5) Sphere:
(a) Alert the diver in the water,

(b) Secure oxygen to diver compartment.

2-6

(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 P02 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. Allother 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 c6mpartment. 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.

@ntrapment

1. Your best insurance for survival. in case of entrap-
ment is the pre-mis*sion 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 thp 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.

S. 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 PC02 meters, and maintain com-
munication on t@e 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.

Administrative (PURA 787M)CARBON DI0XIDE REM0VAL SYSTEMS

Units in this series are assembled from three main camponents;
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 surroun
ding 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 PURA 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 direct
mechanical connection between motor and turbine; 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
environmentall 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 bearins in contact with high pressure environmental oxygen
are specially treated and compatible with any breathing MIX-
tures.

2-16

ELECTRICAL CONNECTIONS - 787M9 Series scrubbers operate on 24
to 6 volts, AC or DC. The motor is a universal type and is
unidirectional; it cannot be externally reversed by inter-
changing leads. Connect two wires from hull pentrator to a
suitable power source. Make certain that all connections are
mechanically tight. Tie down all loose cable with suitable
straps or clamps to guard against accidental snagging Use
only approved explosion-proof switches in pressurized environ-
ments DO NOT make or break Pressure-exposed connections in
oxygen atmospheres.

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
0PERATING UNIT.

MOUNTNG- 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
scrubber 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-relase hook securin the loading cover
penetrate the case through O-ring gland fittings and are, gas-
tight. Apply a drop of APPROVED SILCONE OIL to each rod to
keep it operating smoothly. (See Lubrication and Loading)

FITTINGS and HARDWARE - All stock fittings have been tested
and certified.. Do not endanger safety and certification by
changing or altering installed fittings If modifications are

required return to factory for refitting, testing and certain-
fication. (See Maintenance) DO NOT DRILL ,TAP WELD, OR IN
ANY WAY ALTER THE PRESSURE HOUSING.

ABSORBENT -Any approved carbon dioxide absorbent may be used,
including plastic prepacks -(disposable type). Prepacks are
NOT recommended in -high partial-pressure oxygen atmospheres
because of their flamability. Gas flow through prepacks is
not as efficient as through stock stainless steel refillable
canister. (See Loading and Baralyme/SodaSorb :pH
CO REMVOVABLE - Gas exchange rate is controlled directly by
varying input voltage Unit can be ideally matched to any

system by monitoring CO level and altering the supplied volt-
2
age. In large hyperbaric installations, multiple scrubbers
may be used to hold CO2 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 ab-sorbent chemical. Fill
prior to each use with fresh, dry desiccant. DO NOT OMIT this 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
securing snap-locks to release i the loading cover. Remove the

cover exposing the canisiter. Lift the canister straight out
I
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 an "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 with 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 for 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-locks,
and push it straight down forcing the attached bronze- compres-
sion. ring against the canister. Pull upon 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 f or 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 fldw is through

desiccant canister only. If the case -is punctured., patch'
immediately or carbon dioxide removal will be severely impaired
(See Maintenance).

FOR

REMOTE OXYGEN MONITOR AND RECORDER

(DEVELED 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 (32oF

to 1050 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 #1 & #2 are backed up by Rustrak type recorders; these recorders

produce a permanent record of the oxygen level for later evaluation. Stations

#1 & #2 have a full scale sensitivity of 2 Atm. Abs. Stations #3 & #4 have

a full scale sensitivity of .4 Atm. 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

diode. 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.

Detection and Extinguishing System Components manufactured by
Pyratector, Incorporated, Hingham, Massachusetts for installation
in HBF'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 Hilan 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 !ever on the
.solenoid valve assembly.

Independent detection and extinguishing is provided for'the lazarette,
control console area and O.O.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 Compa rtment. They turn
on an amber lighton 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.

OPERATING AND MAINTENANCE INSTRUCTIONS

WARNING: These instructions must be read and understood by all
individuals who have the responsibility of operating
and sarvicing the Combustible Gas/Oxygen Monitor. The
actions taken as a result or the measured oxygen and
combustible gas levels must be in strict accordance with:
Company and Government regulations. The instrument should
not be used to reasure combustible gas in an atmospheres
either oxygen deficient or containing more than 25% oxygen
by volume.

GENERAL

The Biomarina Combustible. Gas/Oxygen Monitor provides a simple
method of determining oxygen concantracticus and combustible gas levels
in any environment. The instrument may be used for both spot checks and
continous monitoring with alarms. When used as a monitor, oxygen level
and battary voltage are monitored continuously and Combustible gas level
is checked automatically every three minutes. This "sampled data" approach
allows forty hours continuous operation before battery recharging. Easily
portable and simple to operate, the Monitor is automatically temperature
compasated over its full operating range of 5 F to 110 F. The Monitor
requires ingrequent calibration and performs accurately in high humidity
environments. While methane is the calibration standard for the cumbustible
gas monitor, other combustible gases will be detected. If desired, combustible
gases other than methane may be used for calibration.

CAUTIONS
1. The battary must be tested before monitor is used.
2. In combustible gas concentractions above 100% LEL, the instrument will
give incorrect reading. If it is suspected that concentrations higher

Navy Rescue Organizations

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 Orleanse 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 avatlable. 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 proceedin 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 OPNAV Instruction 3130.4A of 29 October 1973. Applicable portions
of Coast Guard Instruction 3130.7D and OPNAV Instruction 3130.4A are presented

C0MMANDANT INSTRUCTION 3130 .7D

Subj: Operations involving Civilian Submersibles

I. Purpose. This Instruction provides procedures to be followed by
the Coast Guard with respect to operations involving civilian submer-
sibles.

2. Cancellation. Commadant 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 an 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 utilization 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 contract for undersea salvage. The
point of contact is the Navy Department Duty Captain at the Pentagon,
as described in 0PNAVINST 3130.4, enclosure (1). When the Navy has responded
and assumed the role of SAR 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 submesible,
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) Info= 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-
mersibles 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 Summary and Characteristics
Manual: Published and revised annually by Commander Submarine Develop-
mant Group One as COMSUBDEVGRU ONE INSTRUCTION 5450.1 and contains
characteristics of U.S. military and civilian submersibles, 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:

COMDTINST 3130.7D
5 DEC 1975

(a) Obtain Navy assistance, if appropriate,by calling the
Navy Department Duey Captain in the Pentagon at the following phone
number, notifying him of the situation:

COMMERCIAL (202) 693-0231

.AUTOVON 22-50231

If appropriate request implementation of SUBMISS/SUBSUNK for civilian
submersibles in accordance with OPNAV INSTRUCTION 3130.4, and the usN
ADDENDUM to NWP 37(B). Send a follow-up message in the format of enclosure
(4) to confirm request.

(b) Respond with appropriate Coast Guard resources, such as On-
Scene Commander rescue platform (buoy tender), traffic control, communi-
cations, an logistics.
(c) Ascertain if there are any other civilian submersibles
available; request that they assist the distressed 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
SUBMERSIBLE OPERATIONS (CG-4790) to all known owners, operators, and
manufacturers of civilian submersibles in the United States and to all

Loss of Power

During a mission the main circuit breakers may trip due

to an overload. ; When this happens all equipment should

be de-energized and the brakers 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.

GENERAL INFORMATION REGARDING
MANNED NON-COMBATANT SUBMERSIBLES

I. 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-
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 XR-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.

Enclosure

4. If the J-S-L I is entrapped and cannot gain it's

freedom by blowing all ballast and thrustering,

time should not he 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 l divers are unable to

free the J-S-L 1,bring them back in and shut

both "A" and "B" hatches. Do not over pressurize.

Release your emergency location buoy, keep calm,

conserve mower, monitor your P02 and PCO2 meters,

and maintain communication on the sound powered

phone.

NOME: 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 1 lock-out diver in the

diver compartment.

that contains a quart of mineral oil.as a lubricant

and has been deflated with a vacuum pump, roiled

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.
