Submerged marine streamer location
Patent
·
OSTI ID:5857755
Method and means are provided for determining the position of a submerged marine streamer towed behind an exploration vessel. An array of at least three transponders secured to the ocean floor generate distinguishable acoustic pulses upon a command signal from the ship. These signals are received by hydrophones housed in the streamer and by the ship. The distance to each hydrophone may be triangulated from the data generated including accounting for changes in velocity between the vessel and the seismic streamer and the bottom transponders during the taking of such data.
