MARINE STRUCTURE HAVING REPLENISHMENT TANK

摘要

PURPOSE: An offshore structure with a supply tank is provided to prevent sloshing phenomenon and to maintain the fully loaded state of storage tanks when the liquefied material level of the storage tanks is lowered. CONSTITUTION: An offshore structure comprises storage tanks(300a-d), a supply tank(200), connection passages(400), and a control module. When the liquefied material level of the storage tanks is lowered due to boil-off gas, the supply tank supplies liquefied materials to restore the liquefied material level of the storage tanks. The connection passages connect the supply tank and the storage tanks. The control module controls the supplied amount of the liquefied materials according to the data of a water level sensor. A reliquefying module is arranged between the storage tanks and the supply tank so that the boil-off gas can be collected, reliquefied, and supplied to the supply tank.
