GMC's LCHS – LNG Simulator offers both MOSS type LNG carriers and Membrane type LNG carrier simulation models.
The Moss type LNG carrier model is based on an IGC type 2G LNG ship with vapour pressures within the atmospheric to 0.25 bars range. The design of the cargo containment system is spherical independent tanks of Kværner-Moss Technology (Moss) consisting of a single wall, insulated, spherical tank, supported by a vertically built skirt. The Membrane type LNG carrier model is based on an IGC type 2G LNG ship with vapor pressures within the atmospheric to 0.25 bars range. The design of the cargo containment system is independent Prismatic tanks which have two barriers forming a thermal insulating membrane tank based on the GAZ Transport and Technigaz (GTT) mark III System.
Layout and realistic visuals of cargo handling system on each model is based on typical system found aboard specific ship type including LNG vaporizers, Forcing vaporizers, HD/LD compressors , heaters , Boil off control and Operation monitoring system based in the cargo control room with remote indications of levels, temperatures, pressures, pump controls, valve controls, ESD controls, temperature and pressure recorders, trim, stress & stability calculators and other systems designed to provide control over the cargo operating system.
