DEVICE TO SET SHIP AFLOAT Russian patent published in 2012 - IPC B63C7/28 

FIELD: transport.

SUBSTANCE: invention relates to water transport, particularly, to setting ships afloat. Proposed device comprises mechanisms to drive ship from bottom. Separation from bottom is performed using two folded elastic waterproof zero-buoyancy shells connected by mesh web to be fitted under ship hull on side opposite that of getting ashore and inflated by compressed air. Note here that elastic shells are developed into pontoons of notable volumes to create required lifting force to set ship afloat. Ship is pulled to deep water by power plants of emergency ship, tug boar, or by combined efforts. Width of mesh web may not exceed emergency ship hull width in midline. Device is fitted under ship hull using cables secured to mesh web, two shallow tug boats, or emergency ship mooring gear.

EFFECT: simple, reliable and efficient device.
