Apparatus for steering a marine seismic streamer via controlled water ejection

Abstract

A marine seismic streamer steering device comprises a body connected between two adjacent sections of the seismic streamer, at least one inlet port on the body, a plurality of outlet ports on the body, and a port control unit which controls water flow through the plurality of water outlet ports. The steering device further comprises a roll sensor which determines rotational orientation of the body and transmits the orientation to the port control unit, a lateral position sensor which determines lateral position of the body and transmits the lateral position to the port control unit, and a depth sensor which determines depth of the body and transmits the depth to the port control unit. The port control sensor then controls the water flow through the plurality of outlet ports based on the transmitted rotational orientation, lateral position, and depth of the body.
