Low temperature liquefied gas tanker ship
Patent
·
OSTI ID:7014322
Bridgestone Liquefied Gas Co., Ltd.'s new LNG cargo tank offers a simplified structure, lower costs, and greater ease of testing. The secondary barrier wall, which covers the bottom and side walls of the cargo tanks, has an outwardly bent, flangelike upper edge which traverses the heat-insulation layer and is connected to the hull in a fluidtight construction. Since the secondary barrier does not cover the tank up to the top, the structure is simplified and material and manufacturing costs are lowered. In addition, the fluidtightness of the secondary barrier wall can be tested at any time by means of a gas-extracting tube which opens toward a space confined by the hull and secondary barrier wall.
