DEVELOPMENT OF THE 3D CONTAINMENT SYSTEM

In the early 1960's Gaz-Transport S.A.R.L. (GT) in France and the McDonnell Douglas Corporation (MDC) in the United States embarked on separate, unrelated programmes to develop a containment system for cryogenic fluids. GT's work led to a containment system for LNG tankers that was based on the use of flat, low-expansion-alloy primary and secondary barrier membranes. This system has seen tanker service for the equivalent of 80 trips around the world in six years of continuous operation. MDC developed a bonded, three-dimensionally (3D) reinforced, polyurethane insulation for the interior of the upper-stage liquid hydrogen tank on the Saturn/Apollo moon rocket. To obtain the containment system performance, safety improvement, and favourable economic characteristics needed for future LNG tankers, the two firms have combined their technical expertise and experience to develop the "GT/MDC Liquefied Gas Containment System." This system integrates the most desirable features of each company's technology. This paper reviews the basic decisions that must be made in evolving an LNG containment-system design, describes the essential features of the GT/MDC system, and summarises the work that has been done to develop and verify this concept for the next generation of efficient, cost-effective, and safe oceanic LNG transportation systems.
