METHOD FOR UNDERWATER VEHICLE POSITIONING NEAR THE WORK SITE Russian patent published in 2022 - IPC B63C9/00 B63G8/40 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and relates to the specifics of underwater technical work for various purposes and the rescue of crews of emergency submarines. To position the underwater vehicle (UV) at the work site, an anchor device is installed on the UV, where heavy anchors are replaced by electromagnetic anchors, and a unit is attached to the UV, in which an electric winch with a cable-cable is placed, through which power supply and control signals are transmitted, and at the end of which an electromagnetic anchor is fixed. When the underwater vehicle is above the object of work, the UV operator turns on the winch to unwind the cable-rope with an electromagnetic anchor at the end. When the anchor touches the metal part of the sunken object, an electric current is applied to the electromagnet. After fixing the electromagnetic anchor with the hull, the operator turns on the winch to unwind the cable, while the underwater vehicle is moved to the second position using the propulsion-steering complex, where, by analogy with the first position, the second electromagnetic anchor is fixed. In the same way, capture is carried out by the third and fourth electromagnetic anchors, then positioning is carried out by selecting the anchor cables by the method of successive approximation to the required point. At the same time, the system is controlled from the UV, and from 1 to 4 anchors can be installed on the UV.

EFFECT: increased efficiency of underwater technical operations using various tools and manipulators.
