    摘要: Deflectors configured to be attached to cables towed behind a vessel for performing a marine survey and associated methods are provided. A deflector has a body including a wing portion and a knuckle portion. The wing portion has substantially flat wings extending away from a position where the body is attached to the cable. The knuckle portion is configured to attach the wing portion to the cable so that the wing portion remains able to rotate about three rectangular axes while being towed underwater.

    摘要: A source element for generating seismic waves includes a housing; a partitioning element placed inside the housing and configured to split the housing in a closed chamber and an opened chamber; and a valve in fluid communication with the closed chamber and configured to supply high-pressure air to the closed chamber to make the partitioning element oscillates. An oscillation of the partitioning element generates low-frequency seismic waves.

    摘要: A real time deflector monitoring system related to a deflector used in a seismic survey system is provided. The system includes a bridle block configured to connect the deflector to a first rope. The system further includes sensors embedded in the bridle block and configured to measure strength and direction of a tension in at least one of (A) the first rope and/or (B) one of rig ropes connecting the deflector to the bridle block. The system also includes a motion detector configured to acquire information related to deflector's motion.
