DESIGN METHOD OF LNG SHIP CARGO SYSTEM CONSIDERING OPTIMIZED BOR

摘要

PURPOSE: A cargo system design method of LNG ship in consideration of increased cost is provided to select the thickness of insulating material and the amount of BOG according to the cost reduction of surplus BOG processing. CONSTITUTION: A surplus BOG(Boil-Off Gas) is calculated from flight information. If the surplus BOG amount generates, surplus BOG amount is calculated according to the insulating material increase. A surplus BOG processing cost is calculated according to the thickness of the insulating material.
