SHIP BOTTOM COVERING Russian patent published in 2024 - IPC B63B3/24 B63B3/14 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding and can be used in construction and repair of bottom structures of ship hulls, operation of which implies possibility of landing on the ground. Bottom covering of the vessel includes a device for protection of the bottom of the vessel during its landing on the ground, made in the form of a pair of closed longitudinal elements located symmetrically relative to the centre plane of the vessel and rigidly fixed on bottom skin. Each longitudinal element contains a support strip, mainly horizontal, inclined side walls, the upper edges of which are rigidly attached to the bottom skin, and transverse stiffeners. Distance between top edges of inclined sidewalls exceeds width of bearing strip. Top edge of one of inclined sidewalls is located in one vertical plane with central axis of ship bottom bearing element closest to it. As a bearing element for one of the inclined side walls, a bottom stringer is used, and the second side inclined wall is made with a corrugated insert, parameters of which should be selected from the condition that the maximum load for it is less than the load causing crumpling of the walls of the floras.

EFFECT: preventing deformation of double bottom structures, which increases reliability and repairability of the housing.
