SHIP SAFETY CONSIDERATIONS IN THE DESIGN AND TESTING OF A NON-METALLIC SECONDARY BARRIER
This paper identifies some important problems of non-metallic secondary barriers for LNG containment systems and summarises principles for their satisfactory design and testing. Three overall types are considered: A. A tight liner placed within the insulation space (as tight as the welded metal primary barrier). B. Tight continuous insulation. C. Insulation-liner composite where each element is not completely tight but the composite controls LNG intrusion. The required tightnesses for the composite system can be obtained with resin-impregnated glass cloth materials used with low-density polyurethane foam to give 3-dimensional reinforcement. Type C construction is used in the GT/MDC system developed by McDonnell Douglass Astronautics in cooperation with Gaz-Transport. The characteristics of this secondary barrier system are briefly reviewed and the results of a programme of qualification/verification testing are discussed. Order from BSRA as No. 51,078.
