FLOATING DOCK SECTION Russian patent published in 2010 - IPC B63C1/02 B63B35/40 

FIELD: transport.

SUBSTANCE: invention relates to ship building. Floating dock section contains pontoon where side towers are installed, ballasting facilities, dock floor with primary framing made as structure of longitudinal and transverse frames, main framing beams resting on it on which beams the decking is placed. The pontoon is divided into central and side ballast compartments by vertical waterproof bulkheads. In the vertical longitudinal pontoon symmetry plane, vertical support bulkhead is installed which bulkhead is made permeable. Relative (to dock width) width of central ballast compartment (size of segment with transverse framing system) is calculated by formula given in description. Longitudinal vertical waterproof bulkheads are placed equally spaced from the vertical support bulkhead. The main framing of the central ballast compartment is executed according to transverse scheme, and the main framing of the side ballast compartments - according to longitudinal scheme.

EFFECT: decreased scuffing of decking in places of framing welding during equipment movement, mainly along dock side towers; reduced pontoon weight; reduced ballast asymmetry and dock tilting.
