A deflector is configured to be attached to a cable towed by a vessel. The deflector includes a foil configured to provide a lift force; first and second bulbs attached to opposite ends of the foil; and a joint attached to the foil and configured to receive the cable. The first and second bulbs are offset by a predetermined distance from a plane that extends through the foil, and at least one of the first and second bulbs has a longitudinal axis that makes an angle (&#x3b8;) with a cord of the foil, the cord extending in the plane.

Deflector for marine seismic survey system

Method and cleaning device for cleaning a seismic streamer. The cleaning device includes a flexible body having a shape that wraps around a longitudinal axis; a movement-generating device attached to an end portion of the flexible body; and first cleaning elements provided on a first portion of the flexible body and configured to clean the seismic streamer. The flexible body is configured to wrap around the seismic streamer.

Streamer cleaning device and method

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.
