LIQUID CARGO TANK HAVING ROTATION UNIT AND MARINE STRUCTURE HAVING THE SAME

摘要

PURPOSE: A liquid cargo storage tank with a rotation unit and an offshore structure with the same are provided to disperse energy by moving liquid cargo in the storage tank with the rotation unit, thereby preventing sloshing phenomenon. CONSTITUTION: A liquid cargo storage tank comprises one or more bodies(100), a rotation unit(110), and a rotation force supply unit(140). One or more bodies are loaded in a cargo loading part and have a storage space for storing liquid cargo. The rotation unit has a rotation part by which the liquid cargo moves upward in the storage space and is arranged in the lower part of the storage space. The rotation force supply unit rotates the rotation part using boil-off gas generated from the storage space.
