Abstract:
A vessel includes a hull, a shaft extending from an upper part of the hull to a bottom of the hull, a turret being rotatably supported in the shaft via a turret bearing, a manifold support structure carrying one or more conduits being rotatably supported on the turret via a manifold bearing. The turret includes a cavity for receiving a mooring buoy carrying one or more risers and one or more vertically displaceable actuation members near the manifold bearing for vertically displacing the manifold support structure relative to the turret between a rotational position in which the manifold support structure can rotate relative to the turret via the manifold bearing and a locked position in which the bearing support structure is rotationally locked relative to the turret.
Abstract:
A system for mooring a vessel at an offshore site comprises at least one floating mooring element with two opposite mooring bodies for receiving therebetween and engaging the hull of the vessel. Each mooring element is movable between an upper position for engaging the hull of the vessel and a lower position in which at least one of its mooring bodies is lowered below the upper position for disengaging the hull of the vessel. Further means are provided for maintaining a substantially stationary position of the mooring element relative to the seabed. Preferably the system comprises at least two mooring elements spaced in the longitudinal direction of the vessel.
Abstract:
A swingable spacing dock is configured to berth a ship spaced from the shoreline and includes a support positioned on shore, a swingable dock arm pivotally mounted on the support, and a powered drive. The dock arm is driven by the powered drive to swing between a ship docking position where the dock arm extends outwardly beyond the shoreline to engage the berthed ship and a storage position where the dock arm is positioned substantially entirely over the shore.
Abstract:
A boat docking unit for small boats secures a boat to a dock structure without use of ropes, anchors or fenders. The unit has a pair of docking arms each having an elongated tubular housing, a telescoping member capable of telescoping movement within the housing. A pair of compression springs mounted in the housing in contact with the telescoping member dampens the wave force so as to restrict yaw of the boat docked at the pier. The docking arms pivotally secure the boat to the dock structure allowing a limited pitch motion of the boat.

Abstract:
An amphibious small boat, including rowing/fishing/motor/sailing boats, canoes and kayaks has a removable, retractable wheeled undercarriage enabling the craft to be trailered or managed singlehandedly on the ground; or the undercarriage retracted inboard. The canoe and kayak undercarriage is easily removed. Working loads are distributed to the fabric of the craft. The boat undercarriage can be manually lever-controlled and the lever anchors the undercarriage. A motorized actuator is also given. An elevated towing hitch is used with all embodiments, and includes a safety, breakaway link for highway needs. Signal/running lights are included with the small boat embodiments.

Abstract:
The present invention relates to a damper for damping the reactionary motion of a wave energy conversion device to wave motion, comprising a damping energy absorber (7) having a reversible non-linear stress-strain response, arranged to damp the reactionary motion of the WEC. According to a first aspect, there is provided a damping structure (2) for a wave energy conversion device (1). The structure comprises a fixed member (6), and a damping member (7) having a reversible non-linear stress-strain response. The present invention also relates to a mooring component (2) for a mooring system (1) and to a method for manufacturing a mooring component (2). The component comprises a deformable element (6) having a reversible non-linear stress-strain response, wherein the response is a composite reversible non-linear stress-strain response.
Abstract:
An apparatus for docking and/or mooring vehicles, particularly water craft and for restraining loads in truck beds or trailers. The apparatus utilizes ropes or cables in housing unit that provides for the extension and retraction of the rope or cables preferably without the need of electrical or manual cranks. The housings are adaptable to be mounted on the vehicle or at an attachment or docking location and are biased to retract but may contain stops or cleats for manually tying off and thus stopping the extension or retraction of the rope or cable. The housings may be further adapted to be flush mounted in relation to surrounding surfaces.
Abstract:
A mooring assembly for a vessel comprises a receiving vessel part, a geostationary part received rotatably in said receiving vessel part and a main bearing assembly connecting the geostationary part to the receiving vessel part. The main bearing assembly comprises at least two separate bearings which are manipulable such that the one or the other or both bearings are in an operative position, thus allowing the non-operative bearing to be replaced, overhauled, repaired and alike in situ.
