Arrangement for containment of liquid natural gas (lng)

摘要

The present invention relates to an arrangement for containment of liquid natural gas (LNG) in a hull compartment of a marine construction comprising a self supporting primary barrier a secondary barrier surrounding the self supporting primary barrier and an access space between the self supporting primary barrier and the secondary barrier wherein the self supporting primary barrier is a liquid tight self supporting LNG tank and is connected with the hull compartment by support devices penetrating the secondary barrier the secondary barrier is a liquid tight thermal insulation connected with the interior surface of the hull nd is sealed to the support devices by a flexible liquid tight seal so that the self supporting primary barrier and the secondary barrier are separately connected with the hull compartment to prevent transfer of forces between the primary barrier and the secondary barrier.
