A fender for fending a ship from a mooring wall comprises a hydraulic cylinder and piston assembly arranged so that compression of the fender is translated into a force to move the piston in the cylinder. Valves couple the hydraulic cylinder to reservoir that is at least partially filled with gas. An overpressure valve allows hydraulic liquid to flow from the cylinder to the reservoir when the fender compression force exceeds a threshold, allowing the fender to be compressed. When the force drops away, a return valve allows hydraulic liquid to return to the cylinder, causing the piston to move to expand fender, following movement of the ship away from the fender. In this way oscillating motion is reduced. A plurality of such fenders may be combined with mooring cable holding devices with a similar mechanism that pays out cable when the movement of the ship from the mooring wall cause the force on the mooring cable to grow. Energy generated from such forces may be used to reduce movement of the ship.

Fender arrangement for docking a marine vessel (1) with a boat landing (2) of a marine offshore structure (3) such as a wind power plant, including at least one fender unit (12, 13) composed of elastically deformable material and provided with a receiving recess (18) for a docking rail (5) of said boat landing (2). The fender arrangement is especially characterized in that fender unit (12, 13) exhibits an internal deformation control cavity (20) positioned at a distance from the receiving recess (18) within the fender unit (12, 13) and extending at least along the width of said receiving recess (18), controlling deformation of the fender unit (12, 13) into forming a gripping hold of a docking rail (5) by compression of the internal deformation control cavity (20) when the fender unit (12, 13) is pressed against the docking rail (5).

A boat hook assembly includes a clamping assembly, which is attachable to a pole. The clamping assembly includes a mechanical clamp in one embodiment and a magnetic clamp in another embodiment adapted to temporarily secure a boat hook which is configured to connect to a receiving member on a boat dock. The boat hook is configured to receive a boat line extending from the boat. The temporary securement of the boat hook by the clamping assembly is overcome by an operator moving the pole in a manner to release the clamping assembly from the boat hook, wherein the boat remains connected to the dock by the boat hook and the extended boat line. The boat hook assembly includes structural element and arrangements to prevent unintentional release of the clamping assembly from the boat hook.

The invention relates to a floatingly mounted and/or mountable platform for the assembly of electrical and/or mechanical and/or pneumatic structural elements in an area of water. It comprises, on the one hand, at least one platform which has at least one floating body or which forms the floating body itself, the floating body being designed such that it always holds an assembly upper side of the platform above a water level in order to be able to mount the electrical and/or mechanical and/or pneumatic structural elements on a surface of the assembly upper side. On the other hand, the invention comprises at least one anchoring element which is mounted on a floor region of a body of water below and distanced from the platform, i.e. below the water level. The invention is characterised in that both the anchoring element and the platform each have at least one magnet element such that the platform is held in the vertical direction by the anchoring element preferably only by the magnetic force that is generated between the two magnet elements.
