LNG CARRIERS OF THE MEMBRANE CARGO CONTAINMENT SYSTEM: SOME ASPECTS OF DESIGN AND CONSTRUCTION

A brief review is presented of studies carried out by Chantiers de l'Atlantique since 1960, including conversion of the Liberty ship Le Beauvais into an experimental LNG carrier equipped with three types of self-supporting tanks. After these preliminary studies , the shipyard decided to concentrate on the membrane cargo-containment system developed by Technigaz and Gaz Transport. Since then, 28 ships of the membrane type have been built and 10 are under construction. This work has given the yard much experience and know-how in this type of construction. The intent of the paper is to deal with some aspects of the design and construction of cargo-containment systems of the membrane type. From the builders' point of view some advantages of the membrane system are: The containment is constructed of small elements that can be massproduced by outside suppliers using existing facilities. The weight of independent pieces is small and heavy cranes are not needed for erection, which can proceed alongside a normal outfitting quay. The erection of the containment can be started as soon as the steel work of one cargo hold is finished and is independent of other outfitting activities, which can proceed in parallel. This gives large flexibility in building schedules. Order from BSRA as No. 54,488.
