Claim:
1. 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 an interior surface of the hull compartment and is sealed to the support devices by a flexible liquid tight seal made as an un-interrupted sleeve around the support devices, so that the self-supporting primary barrier and the secondary barrier are separately connected with the hull compartment and transfer of forces between the primary barrier and the secondary barrier is prevented by the flexible liquid tight seal.
