Level of liquefied gas transporting ship is to pipeline crossing cabin spare

The utility model discloses a level of liquefied gas transporting ship is to pipeline crossing cabin spare, include perpendicularly to bulkhead or deck, peripheral tube, polyurethane plate, rubber slab and two pipe clamps. The peripheral tube welds the via hole department at the leading flank on bulkhead or deck coaxially, polyurethane plate's internal diameter and the external diameter adaptation of pipeline, the mode suit that the external diameter adaptation of external diameter and peripheral tube, this polyurethane plate separate a settlement distance with the front end interfacial of its rear end face and peripheral tube is on the pipeline, the rubber slab package makes the rubber slab form the sheath of an internal diameter and polyurethane plate's external diameter adaptation on the surface of polyurethane plate and peripheral tube, the surface of two lower pipe clamps cover outlying rubber slab of polyurethane plate and peripheral tube under lieing in, the surface of pipeline staggers the polyurethan
