IMPROVED CONCH DESIGN FOR AVONDALE

An improved and simplified design for a liquefied natural gas tanker, based on results of older designs now in operation, is described. The new design achieves reductions in containment tank weight, construction time, and size of ship through more accurate analysis utilizing finite element analysis, application of the regulatory bodies' latest thinking on stress levels, and a reduction of the external water pressure load to the point where it no longer governs design stress. The improved insulation system, utilizing polyurethane foam instead of plywood and balsa wood, the deck arrangement, cargo-handling differences, and a comparison of costs between this and other containment designs are all discussed in the article.
