HULL Russian patent published in 2009 - IPC B63B9/04 B63B25/12 B63B3/32 

FIELD: transportation.

SUBSTANCE: hull comprises planking, decking, framing of hull comprising web beam and elements of longitudinal deck framing. Above deck, girder is arranged, longitudinal vertical plane of symmetry of which is installed in longitudinal vertical plane of web beam. Girder is connected to web beam by means of vertical rods and struts. Sections of girder are arranged as symmetrical relative to diametrical plane of vessel. Girder is mostly arranged as solid, with arbitrary inclination to horizontal plane of longitudinal axes as components of its elements. Vertical rods rest on web beam, preferably, in points of its contact with elements of longitudinal deck framing and/or vertical longitudinal partitions. Points of web beams contact with vertical rods and/or struts are selected outside the sections of existing pipelines installation. Struts are used to reinforce units of vertical rods contact with girder. Units of connection of girder and web beam with vertical rods and/or struts are additionally reinforced with gussets. At section of struts contact with web beam gussets rest against each other. Girder, vertical rods and struts are made of metal profile.

EFFECT: improved structural strength of reequipped vessel hulls, provides for safe operation under conditions of sea basins.
