MULTIFUNCTIONAL NUCLEAR TECHNOLOGY SERVICE VESSEL Russian patent published in 2021 - IPC B63B35/44 B63B35/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and concerns the technological maintenance of reactor installations of nuclear marine facilities. A multifunctional nuclear technological service vessel is proposed, including a storage of spent fuel assemblies (SFAS) of channel and cassette types located in the middle part with holding tanks and containers for temporary storage of SFAS, a storage room for handling equipment for reloading reactor units with fuel assemblies of channel and cassette type, an SFAS reloading room with a traveling crane, a propulsion system and two cargo cranes installed on the deck of the vessel side by side. At least two rotary platforms for storing the above equipment are located in the storage room of the transshipment equipment, located under each other on the decks of the vessel, in the center of each platform there is a support-rotary device with a rotary tower, and electric rotation drives are installed on the flange of the tower, each of the platforms consists of sections interconnected by jumpers, and the sections on one side are supported by balancing levers, including two wheel assemblies that move along the rail, and on the other side are attached to rotary towers, the upper platform has a cut-out for loading and unloading of transfer equipment to/from the lower platform.

EFFECT: mechanization of work is provided, as well as optimal placement of transfer equipment and reduction of time for loading, unloading with subsequent transportation of transfer equipment to the place of works.
