LNG CARGOCONTAINMENT AND ITS INSULATION CAPABILITY ENHANCING METHOD

摘要

Disclosed is an LNG cargo hold. The LNG cargo hold of the present invention includes: a first insulation box filled with particle type insulation materials while the inside is maintained airtight, for firstly insulating LNG stored in a storage tank; a vacuum pressure controller for controlling vacuum pressure in the first insulation box; and a controller for controlling the vacuum pressure controller and maintaining boil off ratio (BOR) in a predetermined range if BOR gets out of the predetermined range in the storage tank.
