Mooring unit for mooring a ship comprising a base, an arm mounted on the base, and a hook supported by the arm for connecting a mooring line of the ship, wherein the arm is movable between a retracted position and an extended position, and wherein the unit comprises an actuating device for moving the arm from the extended position to the retracted position, wherein the arm is mounted on a first part of the base and wherein the first part of the base is rotatably mounted on a second part of the base that is rotationally fixed, to enable rotation of the first part of the base around a vertical axis perpendicular to the horizon.

A semisubmersible with a plurality of surface piercing columns, a plurality of pontoons attached to and extending between pairs of adjacent surface piercing columns, a tunnel side formed between a first pair of surface piercing columns, an additional tunnel side formed between a second pair of surface piercing columns, a tunnel floor formed between the tunnel sides. A tunnel opening formed between the tunnel sides for receiving a floating vessel into the tunnel structure, and a main deck secured to the plurality of surface piercing columns. The semisubmersible can be ballasted to an operational depth and deballested to a transit depth.

A watercraft mooring system comprising a plurality of interchangeable mooring members for the temporary mooring of one watercraft to another watercraft or one watercraft to a stationary object such as a dock. The interchangeable mooring members comprising connecting rod member embodiments with adjustable lengths and connecting rod members without adjustable lengths, vacuum-handle member embodiments that provide an initial vacuum and a continuous vacuum to one or more vacuum cup assemblies, and a cleat connector member embodiment that is interchangeable with a vacuum-handle member. Embodiments of vacuum-handle member providing up to three points of omni-directional pivot functionality between the present invention and a temporarily moored watercraft.

A connector assembly can include a stinger and a sleeve assembly that includes a latching mechanism. An outer surface of the stinger can define first and second grooves located toward first and second ends, respectively, thereof. An inner surface of the sleeve assembly can define first and second shoulders located toward first and second ends, respectively, thereof. The latching mechanism can be in an unlocked position or a locked position. When the latching mechanism is unlocked the stinger can be inserted into or removed from the sleeve assembly. When the stinger is within the sleeve assembly and the latching mechanism is locked, the latching mechanism can maintain a first split ring partially within the first groove and partially on the first shoulder and a second split ring partially within the second groove and partially on the second shoulder to secure the stinger within the sleeve assembly.

The invention relates to a mooring device for mooring a ship, the mooring device having a moored state, in which it engages the ship, and a non-moored state in which it does not engage the ship, the mooring device comprising a base, a movable arm, which is extendable and retractable, a connector carried by the arm for engaging e.g. a ship, a winch, a tensile element having a first end engaged by the winch and a second, opposite end fixed with respect to the second end of the arm and/or the connector, and a distance keeping system configured for keeping a minimum and non-zero distance between the base and the object engaged by the connector. According to the invention, the distance keeping system is integrated with the movable arm. The invention also concerns a mooring system comprising two such mooring devices.

The invention provides a boarding assembly (3) for maritime boarding actions,wherein a device carrier (307) is arranged to be erected, while attached via a flexible joint (303) to a support structure of a marine vessel, so as for an engagement device (305) attached to the device carrier (307) to engage a part of a target marine vessel to be boarded,wherein upon such an engagement an elongated flexible element (322), e.g. a rope or a wire, can be pulled through a support device (325), e.g. a pulley block, of a holding assembly (321) mounted to the engagement device, so as to pull an elongated climbing device (323), e.g. a rope ladder, attached to the elongated flexible element (322), up towards the engagement device (305),wherein the holding assembly (321) comprises an engagement mechanism (328) arranged to engage and retain the climbing device.

Connectors assemblies. The connector assembly can include a stinger and a sleeve assembly that includes a latching mechanism. An outer surface of the stinger can define first and second grooves located toward first and second ends, respectively, thereof. An inner surface of the sleeve assembly can define first and second shoulders located toward first and second ends, respectively, thereof. The latching mechanism can be in an unlocked position or a locked position. When the latching mechanism is unlocked the stinger can be inserted into or removed from the sleeve assembly. When the stinger is within the sleeve assembly and the latching mechanism is locked, the latching mechanism can maintain a first split ring partially within the first groove and partially on the first shoulder and a second split ring partially within the second groove and partially on the second shoulder to secure the stinger within the sleeve assembly.

Watercraft docking apparatus including a flexible clamp attachable to a watercraft to be docked, an elongated pole attached at one end to the flexible clamp, and structure attaching mechanism attached to an opposite end of the elongated pole. The flexible clamp and the structure attaching mechanism are both designed to prevent lateral horizontal movement of the elongated pole.
