  • Patent number: 6082710
    Abstract: A device for retrieving ocean bottom seismic cable as the cable is pulled up from the bottom and hauled aboard a vessel. The cable is first led over a front wheel located on an arm which is pivotally mounted for movement about an axis. The cable is then passed under a second wheel before it is brought aboard the vessel, optionally via one or more additional wheels. A damper is provided between a fixed point on the arm, spaced apart from the axis and a fixed point on the vessel, so that the front wheel is raised in response to lower tension in the cable and is lowered in response to an increase in tension in the cable, thereby counteracting any variations in the tension of the cable.
