PASSAGE STRUCTURE FOR AN LNG STORAGE TANK AND A MARINE STRUCTURE HAVING THE SAME IN WHICH TWO OR MORE ROWS OF LNG TANKS ARE ARRANGED AND CONNECTED IN THE LONGITUDINAL OR WIDTH DIRECTION

摘要

PURPOSE: A passage structure for an LNG storage tank and a marine structure having the same are provided to prevent sloshing and support the load of an upper structure by naturally moving liquefied gas among LNG storage tanks.;CONSTITUTION: A passage structure for an LNG storage tank comprises a lower fluid passage(21) and an upper fluid passage(23). The lower fluid passage is installed adjacent to the floor of two storage tanks(10) which are adjacent in the longitudinal or width direction of a marine structure in order to allow liquefied gas stored in the storage tanks to flow. The upper fluid passage is installed adjacent to the ceiling of the storage tanks which are connected through the lower fluid passage in order to allow gas stored in the storage tanks to flow.;COPYRIGHT KIPO 2011
