SELF-PROPELLED BARGE Russian patent published in 2025 - IPC B63B5/24 

FIELD: ships and other floating crafts.

SUBSTANCE: invention relates to self-propelled floating crafts, particularly, to self-propelled quick-assembled barges consisting of separate modules with hulls made of plastic. Self-propelled barge comprises interconnected hollow, air-filled, watertight modules with lugs and at least one power unit. Each module is made in the form of a plastic housing and is formed by four side and upper surfaces and a bottom; lugs of each module are located at four different levels. Modules are connected to each other by means of fasteners located in the lugs and are laid in rows in at least one continuous lower layer and at least in one upper layer, in which there is at least one recess for placement of goods, each formed on all sides by side surfaces of modules of at least one upper layer and upper surfaces of modules of next lower layer. Layers are connected to each other by means of additional fastening elements, and at least one power unit is fixed in lugs of at least one module.

EFFECT: expansion of operational capabilities due to rapid changes in the specified configuration and/or specified dimensions of the self-propelled barge, including its niches for placing cargo, and at the same time due to the speed, simplicity and reliability of its assembly and disassembly.
