HYBRID MODULAR WATERCRAFT BASED ON COLLAPSIBLE BLOCK MODULES Russian patent published in 2021 - IPC B63B3/08 B63B7/00 B63B35/44 B63B35/34 B63B73/40 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding, in particular to modular, collapsible watercraft: barges, lighters, pontoons, floating platforms, floating islands, etc., made of separate buoyancy blocks (modules). The design of the proposed hybrid modular watercraft on the basis of collapsible block modules includes the upper deck and bottom, equipped at the corners with container corner fasteners - fittings and along the perimeter with bolted attachment points for vertical posts and lock posts for fixing block modules, as well as diagonal extensions. In the internal volume of the block modules, embedded sealed pneumatic elastic tank-cylinders are installed to ensure the buoyancy of the hybrid block module.

EFFECT: reduction in the mass of the hybrid structure, small transport dimensions, and the ability to ballast down and lift the watercraft.
