METHOD FOR DYNAMIC POSITIONING FOR UNDERWATER WORKS Russian patent published in 2018 - IPC B63B27/16 B63B27/36 B63B21/66 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of shipbuilding and concerns the performance of underwater works using underwater equipment, designed for the search and diagnosis of underwater objects, as well as for installation works. Proposed is a method for dynamic positioning for underwater works, using a carrier vessel, which is equipped with a vertically stabilized turntable with a telescopic horizontal mast, on which a multi-link lever hoist is attached, providing descent and lifting of the suspension with technological equipment, while the drives of the above elements of the stabilization and positioning systems are programmed with the GLONASS system, a block of accelerometers on the turntable and a depth sensor on the suspension, intended for fastening technological equipment.

EFFECT: technical result consists in increasing the accuracy of the positioning of underwater equipment at low speeds and shallow depths with high payloads.
