LNG/LPG SHIP SAFETY: LESSONS FROM THE PAST

A discussion is given of the safety features of tankers, with particular emphasis on the design of the tanks: thermal insulation materials such as polyurethane foam, PVC foam, polyesters, fiber glass, balsa wood, and perlite; tank configurations such as tubular modules, spheres, self-supporting types, and membrane types; and structural materials such as aluminum, chromium steels, nickel steels, and Invar. With regards to completely new designs, the "wet wall system" seems to offer the most promise. This system does away with a metallic containment system for the LNG which would be contained within layers of a suitable foamed plastic within the inner hull, the foamed plastic acting as barrier and insulation. This technique has already been achieved for LPG carried at a temperature of about - 40 degree C but has yet to be developed for LNG.
