Patent ID: 8388783

Claim:
A method for manufacturing an improved hull for vessels, containers or equivalents, comprising the following steps: preparing an elastic or viscoelastic glue through mixing at least two components, monitoring and/or controlling of the mixing for determining if a correct desired mixing product has been achieved, applying a layer of the correct mixture of the glue onto the hull or on a first side of a sheet of cellular plastic or other light weight material, mounting of at least one sheet onto the hull, the sheet being equipped with a multiplicity of through—going air evacuation holes which exits on the first and second side of the sheet, respectively, placing a net, a web, a wire or equivalent air permeable material on top of the other side of the sheet, wherein the air permeable material is coated with a bonded release agent, fixing the sheet towards adjacent sheets, wherein at least one fastening element is arranged over a joint between the sheets, mounting a vacuum foil onto the other side of the sheet, for achieving a vacuum between the sheet and the hull when gluing by vacuum suction, observing visually if the glue exits out of the air evacuation holes or not on the other side of the sheet, enlarging the joints between the sheets and refilling with putty compound or strips of cellular plastic together with a bonding agent, and shaping/smoothing the surface of the glued on sheets with abrasive tools.
