摘要： A system for towing a marine geophysical sensor streamer includes a lead in line (5) extending from a tow vessel (7). A streamer front end termination (15) is coupled to an end of the lead in line and to a forward end of the sensor streamer. A floatation device (3) is coupled by a line proximate to the front end termination (15). A winch (10) is disposed on the floatation device to extend and retract the line. A depth sensor is disposed proximate the front end termination (15). A controller (22) is in signal communication with the winch and the depth sensor so that the forward end of the streamer is maintained at a selected depth in the body of water.

摘要： A hydrodynamic foil system for a sensor streamer array includes at least two tow ropes (8) each coupled at one end to a survey vessel (10) and at the other end to a paravane (14), the paravanes configured to provide lateral outward force as the vessel and paravanes are moved through a body of water. A spreader cable (24) is coupled to each of the paravanes. A plurality of laterally spaced apart sensor streamers (20) coupled at forward ends thereof to the spreader cable (24). A plurality of foils (25) is disposed on the spreader cables. The foils (25) configured to provide hydrodynamic lift in a vertical direction as the spreader cables are moved through the water.
