CONCEPT OF MODEL-TESTING OF GAS TRANSPORT/GAZ DE FRANCE MEMBRANE TANK FOR METHANE TANKERS

This paper describes the design and testing of the membrane concept as applied to cargo tanks which was developed jointly by Gaz de France and Gaz Transport. The primary liquid containment barrier is Invar which is attached to insulaton boxes made of plywood. The insulating material is expanded perlite. Static and dynamic forces are transmitted through the insulation to the inner hull of the ship. A very extensive test program was undertaken on each component of the system and prototype cargo tanks to simulate the static and dynamic forces which would be experienced at sea. The U.S. Coast Guard has approved the concept and design. At present, two LNG tankers each with a capacity of 450,000 barrels are being constructed based on this membrane concept to transport gas from Alaska to Japan. (Author)
