Patent number: 10859381Abstract: Techniques for providing instructions to an operator of a sea vessel via a computing device are described. The computing device can request, from another computing device, instructions regarding one or more of an intended course and action plan for the sea vessel, which can include at least one navigational instruction and/or deployment instruction. The computing device can send data to a display device to cause a prompt to be displayed. The prompt can include options regarding the at least one instruction. The computing device can send state information of the sea vessel to the other computing device. The state information can include the received input and location information of the sea vessel. Additionally, data can be received by the computing device from a shore based operator and data can be sent to one or more clients on shore.Type: GrantFiled: March 9, 2020Date of Patent: December 8, 2020Assignee: FUGRO USA MARINE, INC.Inventors: John Darius Robideaux, Dickie Andrew Martin, Stephen John Wesley Underwood, Jacob Nicholas Stanley

Patent number: 8567332Abstract: An advanced bilge keel design for improved ship roll damping performance. The advanced bilge keel design includes curved upper and bottom surfaces and improved free end edge design for providing passive roll stabilization and improved energy dissipation.Type: GrantFiled: June 27, 2011Date of Patent: October 29, 2013Assignee: The United States of America as represented by the Secretary of the NavyInventors: Christopher C. Bassler, Allan Scott Percival, Martin J. Dipper

Patent number: 7841285Abstract: A vessel (10) for traveling on water comprises a hull (20) and a keel (30) comprising a member (34) depending from the hull, the member (34) comprising two limbs (44) each depending from a respective lateral side of the hull (20), the two limbs (44) defining at least in part an enclosed flow path extending in a bow to stern direction, the enclosed flow path being configured to allow water incident on the vessel to flow over inner and outer surfaces of the limbs (44a, 44b). The limbs (44) each have a zero-lift surface which is angled to generate in use a component of hydrodynamic force directed away from the enclosed flow path when there is a net flow of water along the enclosed flow path.Type: GrantFiled: December 20, 2004Date of Patent: November 30, 2010Inventors: Jonathan Sebastian Howes, James Donnelly Macnaghten

Patent number: 7513204Abstract: The disclosure relates to a fin stabilization system adapted to minimize roll about the longitudinal axis of the boat during sharp cornering at very high speeds. In one form, equipment such as a machine gun is mounted to the bow of the boat and targets are adapted to be engaged in high-speed maneuvers when cornering and the deck of the boat is not excessively rolled whereby blocking visibility in a turn.Type: GrantFiled: March 9, 2007Date of Patent: April 7, 2009Assignee: Aluminum Chambered Boats, Inc.Inventors: William L. Hickok, Mark R. Morgan, Richard M Benson, Michael A. Baker

Patent number: 6469641Abstract: The present invention comprises a remote marine monitoring and control system that compiles security information and statistics for on-board equipment on unattended boats, uses a wireless transmitter to send this data to a user over a communications network and allows a user to remotely operate the user's boat in response. Boat operational data can be provided to a user on a variety of personal communication devices and/or through a monitoring web site. These devices can also be used by the user to send a user command to remotely control the operation of the boat. The remote marine monitoring system identifies normal operating conditions for on-board equipment and compares these conditions to current operating activity in order to detect unusual activity. Security information can also be compiled and reported relating to intrusion sensors, keyless entry and the boat's physical location.Type: GrantFiled: February 28, 2001Date of Patent: October 22, 2002Assignee: Beacon Marine Security LimitedInventors: David M. C. Lash, Anthony B. Lash

Patent number: 6176191Abstract: This is a mechanical element intended to control the rolling of FPSO type petroleum production systems which use adapted decommissioned ships as the floating facility. The bilge keel is made up of two lines of plates, continuous or sectioned, in this case with a small separation between each two adjacent sections, mounted along the bilge of the ship, one on either side, at right angles to the hull, and characterized basically by being wider and having a greater total length than the conventional bilge keels used in ships.Type: GrantFiled: March 5, 1999Date of Patent: January 23, 2001Assignee: Petroleo Brasileiro S.A.Inventors: Antonio Carlos Fernandes, Isaias Quaresma Masetti

Patent number: 4970979Abstract: A sailing yacht having a hull and a sectional mast holding a sail, is equipped with a canard rudder and two rolling keels. Each rolling keel has a ballast container. A three point wing system is formed by wings carried by the canard rudder and by the two rolling keels for producing buoyancy, for steering, and for stabilizing. Thus, the three point wing system has a fore wing (9) forming an end wing of the canard rudder and two aft wings (11, 11') forming end wings of the rolling keels (10, 10'). The rolling keels (10, 10') are tiltable about rotational axes extending above the water line approximately in parallel to the hull axis, whereby the rolling keels (10, 10') are normally above the water line and only the long end (14, 14') of the wing (11, 11') dips into the water, so that the end disk wing (15) functions as a lift producing surface. The ballast is shiftable between two ballast containers 17, 17'.Type: GrantFiled: July 27, 1989Date of Patent: November 20, 1990Assignee: Messerschmitt-Boelkow-Blohm GmbHInventor: Ernst-August Bielefeldt

Patent number: 4004536Abstract: A boat is provided with an elongated vane extending along each side of the hull. This vane is supported in a closely spaced relationship with the hull's surface to define a longitudinally extending slot. The vanes so positioned reduce the tendency of the boat hull to drift out on turns, by biting into the water. These vanes may be provided with mechanisms to close off the slot when not needed.Type: GrantFiled: March 17, 1975Date of Patent: January 25, 1977Inventor: Claude Bernier
