  • Patent number: 7347157
    Abstract: The static soft rail launch and recovery system provides an anchor or piling located in a body of water away from the shoreline. The anchor remains at a fixed point under water, while being attached to cables having their opposite ends affixed on land to tension the cables. The cables become like rails due to static tension between the two fixed points. The watercraft is placed on a sling carriage that is slidably mounted on the cables and capable of sliding down the cables to launch the watercraft into the water. The watercraft is recovered by a winch cable tied to the watercraft and connected to a recovery winch. The system may be modified to use a single tow cable, attached to an anchor or piling. The system is used to launch watercraft of various sizes, and other payloads, and may be deployed for military, commercial, or emergency missions.

  • Patent number: 6443086
    Abstract: The present invention is a boat mooring system for stabilizing a boat while docked which allows the effective length of the mooring line to vary for substantially greater distances than that of the prior art. The boat mooring system contains a multi pulley arrangement such that a small movement in a spring tensioning device results in a substantial change in the effective length of the mooring line. Thus, a change in tide, or weather conditions results in a substantial compensating effect.

  • Patent number: 6408781
    Abstract: A mooring system and method for mooring in deep and ultra deep water which allows conventional shallow water floating platforms and vessels to be moored in deep and ultra deep water using a conventional shallow water mooring system, while maintaining an acceptable watch circle. A plurality of buoys are placed at a specific depth below the ocean surface and are tethered at high tension to the ocean floor such that the buoys remain stationary. A shallow water floating platform or vessel can then be moored to the buoys using a conventional mooring system, being in effect “fooled” into believing that the sea bottom is shallower than it actually is.

  • Patent number: 6216628
    Abstract: A vessel includes at least two anchor lines connected respectively at a substantially fixed position near the bow and near the stern of the vessel. At least one of the anchor lines includes at least two branching anchor lines each connected with one end to the anchor line in a connection point and connected with the other end to the seabed. By means of this system, a stable anchoring arrangement is achieved in which the sides of the vessel are easily accessible by for instance a shuttle tanker. The system also allows for a weathervaning action through relatively small angles, for instance between 0 and 90°. In another embodiment, at least one of the anchor lines is connected to a substantially fixed position pulling system such as a winch system for lengthening or shortening the anchor lines. For providing a weathervaning action through a range of about O and 90°, the anchor lines are maintained in a tensioned state by the winch system and are varied in length.
