Deep Submergence Rescue Vessel Corrosion Studies

These studies were initiated (1) to determine the behavior of galvanic
couples composed of different alloy fasteners in hull materials, other dissimilar
couples, and welded alloys, and (2) the protective value of galvanic
anodes, paints and sealing compounds in seawater.
One set of specimens was removed after 6 months of exposure at the
surface in the Pacific Ocean and another set was removed after 1 year.
Sacrificial anodes protected aluminum alloys and type 321 stainless
steel from corroding; however, they did not afford complete protection to
the contacting surfaces of a titanium-aluminum galvanic couple. Four of
seven sealing compounds were satisfactory sealants at contacting surfaces.
Paint coatings prevented galvanic corrosion ot an aluminum alloy when in
contact with 6A1-4V titanium alloy and A-286 stainless steel only as long as
the paint coatings remained intact. After 6 months of exposure, there were
paint failures on seven of nine specimens and on 10 of 10 specimens after 1
year of exposure.

Effects of Environment on Coatings

A study was completed on the effects of pressures equivalent to a
depth of 6,000 feet in the ocean on the blistering of paints applied over
steel. It was found that blistering of paint in the deep ocean is similar to that
in the shallow ocean.
Steel specimens were coated with zinc-rich epoxies and a zinc-rich
Saran, with and without topcoats, and exposed in the deep ocean on STU 1-5.
After 6 months of exposure, the non topcoated zinc-rich organic coatings
were giving excellent protection to the steel panels, even along a scribed cut
made in the paints prior to exposure. Of the test specimens below, the lowerleft
panel was not topcoated and shows bright steel at the scribe maik. However,
when the panels were topcoated with a catalyzed epoxy (lower right),
a Navy alkyd (uipper left), and a silicone alkyd over the Navy alkyd (upper
right), varying degrees of corrosion occurred.

Perhaps John's post should be moved or copied over to this topic in Naval Projects?

DSRV Ahh.. brings back memories of the movie 'Grey Lady Down'!

Recently posted by Periscope Films on YouTube, a 1966(?) film detailing part of North American's DSRV efforts, entitled "North American Aviation's (NAA) Deep Submergence Systems Program Office Deep Submergence Rescue Vehicle Mockup Studies."

Periscope Films describes it accordingly:
"Made in 1966 as part of North American Aviation's bid to produce the U.S. Navy's Mystic Class DSRV Deep Submergence Rescue Vehicle, this rare and unique film gives a behind-the-scenes look at the development of this revolutionary rescue submersible. The film shows how aircraft and spacecraft simulators were used to study the problems that the DSRV would encounter, and two different mock-ups were designed and built to demonstrate (1) a spherical hull design and (2) a cylindrical hull design. . . ."

The title card at the very beginning of the film states:
"This film is Volume VIII Appendix 18 of the North American Aviation, Inc. proposal responsive to the US Navy RFP No. SP001-0139-66 for a Deep Submergence Rescue Vehicle."

The original concept for the DSRV, as proposed by the Deep Submergence System Review Group in 1963.

Should a submarine sink, a proposed rescue vehicle which will carry to operators and 14 survivors, shown in this diagram, is recommended by the Deep Submergence Systems Review Group. Master Caption: Following the loss of the submarine USS Thresher in April 1963, the Secretary of the Navy established the Deep Submergence Systems Review Group to analyze the requirements for placing man at great ocean depths. The study included an examination of plans for the development and procurement of components and systems related to the location, identification, rescue from and the recovery of large and small boats, including submarines, from the ocean floor.
