  • Patent number: 9151859
    Abstract: A system for a more efficient towing of a marine seismic array comprising one or more diverters attached to each lead-in cable. Because each lead-in cable has its own diverter, the need for dedicated towing ropes and taglines between lead-in cables is eliminated, thereby reducing the overall drag and fuel consumption. The diverters of the present invention are directly attached to the respective lead-in cables and are submerged, eliminating the need for taglines and additional flotation. The diverter of the present invention comprises of either a single span-wise hydro foil or two foil sections and is steerable. Similarly, the diverters of the present invention can be installed on the umbilical cables of seismic source subarrays to obtain the same benefits. As such, at least one diverter of the present invention can be attached directly to at least one umbilical cable of the seismic source subarray.

  • Publication number: 20150090172
    Abstract: A variable rigidity tow cable for attaching a first vehicle with a second vehicle. The tow cable includes a tension control cable having a first end and a second end. Tension on at least one of the ends of the tension control cable can be controlled to increase or decrease the length of the tension control cable. A plurality of beads are slidingly disposed on the tension control cable between the first end and the second end. The beads are free to move relative to one another on the tension control cable when the tension control cable is slack, and the beads are engaged with each other to form a rigid structure around the tension control cable when tension is applied to the tension control cable.

  • Patent number: 8943991
    Abstract: In one embodiment of the invention, a rope tender is rotatably affixed to the center pull on the tower to carry the rope over wakeboard racks. The rope tender is clamped to the center pull on the tower by a clamp. The rope is then pulled through an end loop on the rope tender and attached to the center pull on the tower. In one embodiment, the rope tender is looped one or more times in the middle to achieve a flexible, spring effect for the rope tender. The rope may also be pulled through the middle loop for support.

  • Publication number: 20140352598
    Abstract: This discloses a water ski rope safety device. Water ski ropes can become disconnected from the tow boat. They can also become loose or gain excessive slack. In such cases, the rope can whip around or entangle the skier. Any of these might injure the skier. The safety device prevents such a disconnected or loose rope from entangling or striking the skier. The device consists of a flexible sleeve into which the rope is contained along with other components which accomplish the purpose.

  • Patent number: 8902696
    Abstract: A technique for seismic surveying is presented in which a towed array, marine seismic spread, includes a plurality of streamers and a deflector system. The deflector system laterally spreads the seismic streamers, wherein at least one streamer in the spread is deflected using more than one deflector attached to the tow cable or streamer, and where the deflectors are not connected to a float on the sea surface. Other aspects of the technique include methods for towing such a spread and for controlling such a spread. Still other aspects include computing resources which may be used to perform the methods.

  • Patent number: 8817574
    Abstract: A compound buoy. At least some of the illustrative embodiments are buoy systems that include: a surface buoy; a subsurface buoy comprising an elongated outer body; a connector disposed on the lower surface; and a winch having a line, the line coupled between the surface buoy and the subsurface buoy. The buoy system has first configuration in which the upper surface of the subsurface buoy abuts the surface buoy, the abutting relationship held by tension in the line, and the buoy system has a second configuration where a distance between the surface buoy and the subsurface is limited by a length of the line spooled off the winch. In operation, the subsurface buoy supports more of the subsurface load than the surface buoy.
