EFFECTS OF THE DEEP-OCEAN ENVIRONMENT ON MATERIALS.
Abstract
A research program to determine what materials are suitable for use in the construction of deep-ocean structures and facilities is delineated. The program involves (1) the exposure of a wide variety of constructional materials in deep-ocean environments, and (2) the exposure of companion specimens in laboratory-simulated deep-ocean environments. A submersible test unit carrying 1318 specimens of 301 different materials was placed on the ocean floor on 29 March 1962 in 5300 feet of water for an exposure period of 6 months. Five additional units are proposed, one each for 12 and 24 months submersion at 6000 feet and one each for 6, 12, and 24 months submersion at 12,000 feet on the ocean floor. A system of medium sized (9-inch ID) pressure vessels capable of simulating various aspects of the deep-ocean environment, with a pressure range from zero to 20,000 psi, has been fabricated and will be in operation early in FY-63. A large (18-inch ID) pressure vessel with similar capabilities is under procurement and is expected to be in operation in FY-63. (Author)
