Carrying cryogenic fluids such as LNG or LPG aboard a ship poses some unique design
challenges. The extreme low temperatures of these fluids require low thermal conductivity
insulation, and may also necessitate heating in various ship locations to prevent exotic
steels from being required throughout the ship’s hull. The accurate determination of the
heat transfer between the sea water, outside air, and the cargo is critical to ensure the
tank and bulkhead arrangements are feasible.
