摘要： A paravane for a seismic acquisition system includes a float, a frame suspended from the float, deflectors affixed to the frame, and means for coupling a tow rope to a lead-in functionally extending between a forward end and an aft end of the frame. The paravane includes means for selectively changing an effective position along the lead-in of the means for coupling the tow cable.

摘要： In one embodiment the invention comprises a method for performing a repeated marine seismic survey which includes towing at least one seismic source behind a seismic survey vessel substantially along the path of a previously conducted seismic survey, determining the position of the at least one seismic source during the repeated marine seismic survey and comparing the determined position of the at least one seismic source with a position of a seismic source during a previously conducted seismic survey. The position of the at least one seismic source is adjusted in response to said comparison.

摘要： An ocean bottom cable system includes a sensor cable configured to be extended from a vessel to the bottom of the body of water. The sensor cable includes a plurality of seismic sensor units at spaced apart locations. A lead in cable is coupled at a to at least one of the vessel and a buoy, and to an aft lead in cable segment. The segment includes a cable loop to compensate water-caused motion of the lead in cable substantially without moving the sensor units. A first swivel is disposed between a forward end of the sensor cable and an aft end of the aft lead in cable segment. The first swivel enables relative rotation between the sensor cable and the segment. At least a second swivel is disposed between the second end of the lead in cable and a forward end of the aft lead in segment.

摘要： An ocean bottom cable system includes: a cable adapted to be extended from a vessel at the surface of a body of water to the bottom of a body of water. The cable includes at least one electrical conductor or at least one optical fiber. A plurality of sensor units is disposed at spaced apart locations along the cable; and at least one swivel is disposed in the cable between the vessel and at least one of the sensor units. The swivel is adapted to enable relative rotation thereby relieving torsional stress between ends of the cable coupled thereto, and is adapted to transmit axial force along the cable therethrough.
