METHOD OF UNDERWATER HANDLING OPERATIONS PERFORMING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B63C7/02 B63C7/10 

FIELD: machine building.

SUBSTANCE: invention relates to ship lifting and rescue operations in sea and inland waters. For performing underwater handling operations switching on positioning of underwater in vertical and horizontal planes above object to be lifted handling device and it is lowered onto object to be lifted. Prior to lifting three-dimensional model is created of located on bottom object to be lifted with handling device located above it and locked at bottom. Simulating support consoles moving. Engineering and manufacturing inserts into consoles support elements with provision of uniform distribution of contact load at object hull local sections. During lifting performing comparison of retracted support consoles with support elements and their inserts real spatial position relative to object hull with three-dimensional model. Complex of hoisting equipment includes lifting-transportation module, groups of pontoons with air supply and discharge system, winches, object capturing device and control center with possibility of object spatial position real time monitoring and displaying.

EFFECT: achieved is maintaining object hull integrity.
