Abstract: A device and a method for laterally steering a streamer cable towed underwater behind a seismic survey vessel. The device includes a cable-steering assembly rotatably attached to a streamer cable (24). The assembly includes a body to which one or more wings (32,33) are mounted. The wings are arranged to pivot about pivot axes (36,37). The assembly is ballasted so that the pivot axes of the wings are largely in a vertical plane. A conventional cable-leveling bird is converted to one version of a cable-steering device by ballasting to maintain the pivot axes of the bird's wings largely vertical. With an orientation sensor for sensing the orientation of the wings, the cable-steering device adjusts the angle of the wings to provide a sideward component of force to steer the streamer.

Abstract: A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable. A cuff attached to an external device is in the form of a C-shaped cylindrical ring with a circular inner surface. A gap in the ring interrupts the inner surface. A throat is formed in the ring by the gap, which extends the full length of the cuff across the ends of the C. The spacing between the ends of the C across the throat defines the width of the gap. The width of the gap is slightly larger than the diameter of the cable so that the cuff can be slipped over the cable through the throat. The width of the gap is smaller than the diameter of the circular race so that, when the cuff is slid into position on the race, the cuff cannot be removed radially from the race. The inner surface of the cuff rides on the race to allow the cable to rotate inside the cuff. The race can include a circumferential groove for retaining a retractable pin extending from the external device to snap the device in place and a raised circumferential shoulder to further restrain the cuff and attached device from sliding along the cable.

Abstract: A battery operated system responds to coded acoustic signals for releasing a buoyed housing from an underwater anchor to carry a retrieval line attached to a retrievable underwater object to the water surface. A novel tethering mechanism is provided for attaching the housing to a line 38 tethered to the anchor and for releasing it in response to the coded acoustic signals. The tethering mechanism operates in two diverse modes. Thus, the housing is released from its tether line thermally by battery power which melts an expandable wax body in a thermal actuator 36 to move an actuating member 37 through a line release stroke. The tether line is attached by a manually actuated latching mechanism 45, 47 provided for retethering the housing by resetting the latching mechanism without draining battery. The exit angle of the line leaving a lower latching compartment outwardly is restricted to prevent substantial changes in line orientation thereby to reduce fouling of the tether line in response to underwater currents. The tether line attaching mechanism comprises in separate embodiments either a set of line clamping cams or a latched set of levers, either of which releases the line in response to thermal movement of an actuating member.
