  • Publication number: 20220126972
    Abstract: A vessel braking control system for a marine vessel that utilizes one or more of the vessel's features and effectors to increase the drag on the vessel both through increased drag on the features and effectors themselves and by creating a downward force on the vessel as a whole, increasing the wetted hull area and increasing hull drag thereby; the control system operates to place the features and effectors in a braking state through rotation relative to the vessel's direction of travel and relative to the water's surface, and may automatically return the features and effectors to their normal operating state upon the vessel's reaching a detected, predetermined speed.

  • Patent number: 10538299
    Abstract: A motion control system for a ship has one or more sensors generating sea condition data and at least one ship control system. Analyzer software receives the sea condition data and predicts a sea condition event. Calculator software calculates one or more commands in preparation for the sea condition event. Interface software communicates the one or more commands to the at least one ship control system and the at least one ship control system implements a command in advance of the event. The at least one ship control system may comprise a ride control system having one or more motion control devices. The at least one ship control system may also comprise an auto pilot system.

  • Patent number: 10246170
    Abstract: A marine vessel stabilizer and control including a fin having a stem extending into the hull. An arm is connected to the stem and extends towards a connector which is connected to a rod. A housing is connected to another end of the rod and a screw passes through the housing. A motor is connected to the screw and configured to rotate to rotate the fin. A controller is connected to the motor, a speed sensor, a roll sensor and a fin position sensor such that a control signal can be calculated and the position of the fin can be determined to reduce roll of the vessel both when making headway and when at rest (zero speed). When the vessel is at rest, the fin is be configured to rotate through maximum angles greater than 15 degrees from either side of a neutral position.

  • Patent number: 8534211
    Abstract: A variable geometry fin for use in a ship stabilization system is provided. A stabilization element adapted to extend below the water line of a ship. The stabilization element has a foil body and a trailing edge assembly extending from inside of the foil body. The trailing edge assembly includes an extension body having two opposing surfaces, a trailing edge attached to an end of the extension body, a vortex generator having protrusions and/or recesses on the two opposing surfaces, and at least one support guide located on an outboard side of the extension body.
