METHODS OF LOWERING AND LIFTING FOR SUBMERSIBLE VEHICLES AND OTHER PAYLOADS Russian patent published in 2017 - IPC B63B27/36 

FIELD: transportation.

SUBSTANCE: surface support vessel contains a lifting system and a method for lifting payload from an underwater location. The system for lifting payload from the underwater location comprises a hoisting rope, a gripping unit equipped with a propulsion device, a gripping structure for attaching the gripping unit to the payload, a gripping structure for lifting the payload, and a winch with the function of compensating vertical oscillations for releasing the hoisting rope and lowering the gripping unit to the payload. To lift the payload from the underwater location, the direction of the gripping unit in the water to the payload, the attachment of the gripping unit to the payload and the lifting of the payload by tension are included. The gripping unit is attached to the hoisting rope held by the winch with the function of compensating vertical rolling. The winch is located on the surface vessel for carrying the hoisting rope to the payload.

EFFECT: ease of cargo positioning and lifting under different conditions of the sea.
