ABSTRACT:
A marine seismic streamer steering device comprises at least two hinged sections pivotally coupled to each other and connected between two adjacent sections of the seismic streamer, and a bend control unit that controls bending of the hinged sections relative to the longitudinal axis of the seismic streamer. The steering device further comprises a roll sensor which determines rotational orientation of the body and transmits the orientation to the bend control unit, a lateral position sensor which determines lateral position of the body and transmits the lateral position to the bend control unit, and a depth sensor which determines depth of the body and transmits the depth to the bend control unit. The bend control unit then controls the bending of the hinged sections based on the transmitted rotational orientation, lateral position, and depth of the body.
