TOWED UNDERWATER VEHICLE, EQUIPPED WITH SONAR EQUIPMENT FOR DETECTING SILTING FACILITIES AND PIPELINES, AND THEIR SUBSEQUENT MONITORING Russian patent published in 2017 - IPC B63C11/48 B63G8/42 G01V1/38 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the production of underwater operations to probe the seabed, pipeline routes with geo-referenced detection silted objects. Towed underwater vehicle (TUV) is designed as a hollow cylindrical body with a removable head and the tail stabilizer, equipped with a device deepens and computationally-control module and connected to the ship-towing cable-rope. Sonar equipment includes a parametric profiler, consisting of an antenna radiating parametric pumping and receiving antenna, means of processing and recording of sonar signals. TUV further comprises an active sonar, n number of uninhabited small self-propelled platforms located aft of the TUV and equipped with a propulsion system, automatic traffic control system, ballast-equalization system, chassis, magnetometric flaw, an identifier of explosives, poisonous and radioactive substances, a small-sized underwater television apparatus. The vessel is equipped with a towing-control system pits small-sized self-propelled platform.

EFFECT: invention provides the detection of underwater objects by providing access to hard to reach items, surveyed underwater objects and enhanced functionality.
