Ship hull for, e.g. oil and chemical ships, includes cellular plastic material between inner hull and outer hull made of high strength steel and having closed cells for improved buoyancy and energy absorbing capability

摘要

A ship hull comprises an inner hull made of steel or aluminum built on a supporting structure of frames, stringers, longitudinals; and an outer hull made of a high strength steel. Between the inner and outer hull, a cellular plastic material is applied having chiefly closed cells for improved buoyancy and energy absorbing capability. At external strain, the outer hull and plastic material jointly constitute an energy absorbing deformation zone. An independent claim is also included for a method of manufacturing the inventive ship hull comprising attaching a layer of cellular plastic material having closed cells to the inner hull and a high strength steel layer acting as the outer hull.
