PERM-BAR II--A NEW CONTAINMENT SYSTEM FOR LNG CARRIERS
Owens-Corning Fiberglas has engineered a membrane containment system that fulfills the rigid performance requirements for cryogenic marine carriers. After a detailed survey and review of the marine industry's unique needs in these specialised carriers, specific performance parameters were compiled, followed by acceptance criteria for each parameter. The purpose of these acceptance criteria was to define the capability of the system design or component to meet the performance parameters. This new containment system consists of pre-engineered and factory-fabricated panels and splines (joining sections). The panels are mechanically fastened to the ship's hull system. The panels and splines are manufactured complete with all the barriers and insulation cores, allowing the total containment to be applied in one step. The panels are of sandwich construction. The primary and secondary barriers are made from a specially developed fiberglas-reinforced plastic laminate (FRP). This new laminate marine barrier. It has very high tensile strength, can be continuously and rapidly cryogenically shocked, is impervious to gas transmission, is resistant to hydrocarbons, and has relatively low heat conductivity and capacity. Furthermore, it will retain these properties over the 25-year life of a ship, while providing excellent barrier protection for the insulation cores and ship hull system. Unlike metal membranes, it is used structurally, fastening directly to the hull, and offers high impact reistance.
