AUTOMATIC DEVICE FOR DEPLOYING AND WRAPPING OF BOTTOMED ANTENNA UNDER WATER AND UNDER ICE COVER Russian patent published in 2018 - IPC G01V1/38 B63B21/66 

FIELD: radio engineering, communication.

SUBSTANCE: claimed automatic device for deploying and wrapping bottomed antennas under water and under the ice cover, in which a body shape of the underwater device is proposed. It is in the form of a vertical disk that provides placement of coils with a long seismic streamer long and vertical stabilization of the underwater device. The device combines the functions of the power cable of the underwater device and the seismic streamers, which are coiled, where the coils are an element of the body of the underwater device. Also, systems of engines, propellers, valves, sensors, cable layer and electronics unit, providing automatic or controlled motion of the underwater device rounding the bottom profile at a given distance from it and deploying-wrapping of a seismic streamer to the seafloor in the underwater position. If there is an ice cover, the underwater device with a self-deploying seismic streamer can be submerged into water from the board of a carrying icebreaker into the ice hole it formed, after automatic or controlled deployment of the seismic streamer to the seafloor with subsequent registration and recording of seismic signals occurs. After registration and recording is complete, the seismic streamer is automatically wrapped and the device is lifted onto the board.

EFFECT: ability for automatic deployment and wrapping of a long-bottomed antenna for seismic survey and seismo-acoustic monitoring of offshore hydrocarbon fields regardless of climatic conditions and ice conditions, and also effective obtaining of seismic survey data and seismo-acoustic monitoring in real-time.
