A walk-to-work system for allowing personnel and/or equipment to move between a vessel and a wind turbine includes a gangway system and an elevator system positioned with a radial offset from the gangway system. The gangway system includes a height adjustable elongated pedestal and a gangway. The height adjustable elongated pedestal has a first elongated pedestal end mountable onto a deck of the vessel. The height adjustable elongated pedestal includes a first pedestal part and a second pedestal part height adjustably coupled to the first pedestal part. The gangway is rotationally coupled to the height adjustable elongated pedestal at a height H.sub.g from the first elongated pedestal end such that the gangway is radially extending at a length L.sub.g from a center axis of the height adjustable elongated pedestal. The elevator system includes a height adjustable elongated elevator having a first elevator end mountable onto the deck of the vessel. The height adjustable elevator includes a static elevator part and a displaceable elevator part height adjustably coupled to the static elevator part. The elevator system includes a drive system, an elevator car, and a lifting device. The drive system is configured to displace the displaceable elevator part relative to the static elevator part along the elevator's height. The elevator car is movably connected to the height adjustable elevator. The elevator car is configured to be elevated up to the same height as the gangway for allowing access between the elevator system and the gangway system. The lifting device is configured to move the elevator car of the height adjustable elevator.

A personal watercraft with cargo-carrying surface and an anchor rail mounted on a surface of the personal watercraft. The anchor rail being adjacent to the cargo-carrying surface and exposed to an environment. The anchor rail can include an outwardly facing surface exposed to the environment, and the anchor rail is secured to the personal watercraft in such a manner that the outwardly facing surface is recessed relative to the cargo-carrying surface to form a recess or that the outwardly facing surface is flush with the cargo-carrying surface.

A control system for a suspension system of a multi-hulled vessel, the vessel including a chassis portion, at least two hulls moveable relative to the chassis portion. The suspension system of the vessel provides support of at least a portion of the chassis above the at least two hulls, and includes adjustable supports and at least one motor to enable adjustment of a support force and/or displacement of the adjustable supports. The control system includes a fender friction force input for receiving at least one signal indicative of a friction force on a fender portion between a fixed or floating object and the vessel chassis portion, and in response to the fender friction force input, the control system is to adjust the support force and/or displacement between the chassis portion and the at least two hulls to reduce or minimize the friction force on the fender portion.

A boarding/disembarking apparatus is removably attached to a vessel to assist in boarding and disembarking from the vessel. An upper end of the apparatus engages the vessel's gunwale or transom and the lower end of the apparatus defines a step or platform, and a hull plate rests against the hull. In a first embodiment the hull plate is hinged to conform to the angular hull of the vessel. In a second embodiment the hull brace allows adjustment of the position of the apparatus relative to the boat.

An offshore transfer system includes an arm construction with a primary measurement system to measure and compensate for relative movement of an element relative to an external reference when the element is supported by the arm tip, as well as a secondary measurement system to measure and compensate for relative movement of the arm tip relative to the element when the element is put down and no longer supported by the arm tip.

Marine fender (1) for engaging an offshore structure (10) during a transfer operation. The fender (1) comprises a mount (3) for fixing the fender (1) to a vessel (5). An engagement part (2) engages with an opposing surface (11) of the offshore structure (10) when the vessel (5) and opposing surface are forced together such that interface friction resists movement of the engagement part (1) over the opposing surface (11). A coupling (4) is provided connecting the engagement part (2) to the mount (3), wherein the coupling (4) comprises a regulating part for regulating the velocity of movement of the engagement part (2) over the opposing surface (11).

A water vessel boarding ladder device and method of manufacture are described herein. The boarding ladder device may include one or more of a ladder portion, a handle portion, a coupling portion, and/or other components. The coupling portion may be configured to provide a variable rotational relationship between the handle portion and the ladder portion during simultaneous rotation of the handle portion and the ladder portion.
