FIELD: physics, navigation. ^ SUBSTANCE: method is realised as follows. At the bottom of the sea there is an object whose three sides, in the simplest case, are joined in series to identical anchor-chains, anchors, ropes, main loads, strong halyards, additional loads and corresponding radiosonic buoys. When the vessel approaches a design point, a hydroacoustic coded signal is emitted. The first radiosonic buoy (RSB) receives the control hydroacoustic coded signal, after which the radiosonic buoy rises to the sea surface. After technical or visual detection of the radiosonic buoy on the sea surface, the vessel approaches the given point and raises the object. ^ EFFECT: provision for fast detection on a large surface, rapid preparation for raising, including in bad weather conditions: wind, fog etc, and bad hydrophysical conditions: high sea waves, strong undercurrent etc, and raising an object from the bottom of the sea to the surface at minimal time and financial costs. ^ 5 dwg |
