SHIP HULL Russian patent published in 2018 - IPC B63B3/24 B63B3/20 B63B3/00 B63B43/18 

FIELD: ship building.

SUBSTANCE: invention relates to the field of shipbuilding and relates to the design of ships capable of withstanding the power of an underwater explosion without destroying the hull. Ship hull contains a hermetic and rigid inner body that is rigidly and hermetically fastened to the extreme ends of the ship hull, and a hermetic and resilient outer body that encloses the inner body and is resiliently and hermetically fastened to the extreme ends. Machines and mechanisms are mounted in the inner body. Outer body is made of an elastic material, preferably of basalt fiber reinforced polymer, and comprises a thick walled bottom part, coupled with the end and board sections of a smaller thickness, decreasing respectively to the extreme ends and to the top, with the possibility of elastic deformation during water hammers produced by a blast wave. Deck floor is rigidly fixed to the extreme ends of the ship hull and to the upper edges of the board sections of the outer and inner bodies. Gap between the inner and outer bodies is not less than the allowable elastic deflection of the outer body.

EFFECT: technical result is expressed in increasing the survivability of the ship.
