Patent number: 7731157Abstract: A heave compensation apparatus and method for a winch or crane system, the winch or crane system preferably for a vessel and including a lift wire for attachment to a load. The apparatus includes a vessel motion measurement device which may be in the form of a motion reference unit for measuring the motion of the vessel, and a control device or computer capable of receiving an output from the vessel motion measurement device and controlling the winch or crane system according to the movement of the vessel, so as to stabilise the load. The apparatus may further optionally include one or more of a lift wire tension measuring device for measuring the tension in the lift wire; a lift wire distance measurement device which measures the length of lift wire that has been paid out; and a load motion measurement device for measuring the motion of the load.Type: GrantFiled: March 18, 2005Date of Patent: June 8, 2010Assignee: SUBSEA 7 LimitedInventor: Daniel Davidson

Patent number: 7699015Abstract: Sub-ordinate and host maritime vessels are connected to each other by a tow loop trailed by the host vessel through a capture frame which engages the sub-ordinate vessel. The capture frame acts to engage the sub-ordinate vessel in the transitional coordinate space shared jointly between the sub-ordinate and host vessels, which vessels can be either or both surface-going, submersible, and/or non-surface vessels. The capture frame possess features which allow it to disengage from the host vessel while remaining semi-related and recoverable by a linkage of one or more tensioned lines to the host vessel during the time that its tow loop is connected to the sub-ordinate vessel.Type: GrantFiled: March 14, 2007Date of Patent: April 20, 2010Assignee: Lockheed Martin Corp.Inventor: Brian R Said

Patent number: 7685957Abstract: A ship has interchangeable mission modules. For example, a ship has a frame with a mission-module bay disposed therein. The bay is operable to receive a mission module having a mission-module system and an interface that facilitates the coupling between the mission-module system and the ship. As such, a plurality of different types of mission modules can be interchanged quickly and easily to provide the ship with different mission capabilities. Each mission-module is generally self-contained such that all the equipment necessary to perform the specific mission is contained within the single mission-module. Each mission-module is either a single unit or multiple units combined together to form an integrated unit. Thus, the ship is capable of transitioning from one mission to another simply by ejecting one mission module and replacing with another mission module.Type: GrantFiled: November 12, 2003Date of Patent: March 30, 2010Assignee: Lockheed Martin CorporationInventors: Terrence W. Schmidt, Gary M. Noland, Anthony J. Mannino

Patent number: 7654211Abstract: A vessel transfer system utilizes a larger, surface effect vessel with a hull and a cargo deck, having a pressurized volume of air under its hull. The larger vessel cargo deck is lowered relative to a water surface in order to receive a smaller vessel. Lowering is achieved by depressurizing the volume of pressurized air under the hull. Movable propulsors on an air cushion vehicle permit efficient operation under way in an outer position, while minimizing the envelope dimensions for stowage in a well deck, providing clearance from bridges, docks, etc. in an inner position. In the outer position, the propellers operate in more uniform inflow conditions, resulting in improved performance and lower noise levels. In addition, the craft can be arranged to use a full width stern ramp resulting in time saved during cargo loading/unloading. The propellers will be less likely to ingest green water in high sea states.Type: GrantFiled: December 6, 2006Date of Patent: February 2, 2010Assignee: Textron Inc.Inventors: Kenneth J. Maloney, W. Keith Dubose, E. Douglass Whittaker, Brett G. Martin, Robert G. Moore

Patent number: 7621230Abstract: A method and apparatus for cargo transfer at sea, more particularly, a flow-through vessel and related method for the at-sea and underway launching and loading of air-cushion vehicles. The vessel includes a hull having a forward end and an aft end, a continuous deck extending from the forward end to the aft end of the hull, a forward ramp attached to the continuous deck at the forward end of the hull, and an aft ramp attached to the continuous deck at the aft end of the hull. At least a portion of the continuous deck is uncovered and accessible from above the deck.Type: GrantFiled: April 20, 2007Date of Patent: November 24, 2009Assignee: The United States of America as represented by the Secretary of the NavyInventors: Robert W. Anderson, Stuart G. Ullman, Kellie L. Redcay, Ryan T. Hayleck, John F. O'Dea, Sean M. Gallagher, Christopher J. Doyle, Donald R. Jacobson
