Description

technical field

[0001] The invention belongs to a transverse horizontal control towed linear array deployment device and method mainly used for marine towed cables for marine seismic exploration. Background technique

[0002] At present, the number of offshore streamers used in seismic exploration is also increasing, and the distance between them is getting smaller and smaller, so the requirements for their shape are becoming more and more strict. Various reasons such as the difference in cable geometry will make it bend, which may cause entanglement between two adjacent tow cables, or collide with each other and damage the equipment inside, so it is necessary to control the horizontal position of the tow cables . Contents of the invention

[0003] The purpose of the present invention is to provide a marine towed linear array three-wing balance deployment device and a method for determining the zero angle of attack of the wing plate, so as to solve the problem of automati...
