LIQUEFIED GAS STORAGE TANK AND MARINE STRUCTURE COMPRISING THE SAME

摘要

Provided are liquefied gas storage tanks which are arranged in two lines around a longitudinal copper dam in order to suppress sloshing and to support the load of an upper structure at the same time, and a marine structure comprising the storage tanks. The liquefied gas storage tanks are respectively installed in plural spaces which are partitioned off by a copper dam installed inside the hull of the marine structure, and are arranged in two lines inside the marine structure. The copper dam comprises one or more longitudinal and widthwise copper dams which are respectively extended in the longitudinal and widthwise directions of the hull. The liquefied gas storage tank is sealed and thermally insulated by consecutive sealing and thermal-insulating walls without disconnection.
