Problems solved by technology

[0005] All known docking devices are not designed to operate when wave heights exceed 2 meters, so access to offshore structures is dependent on weather or sea conditions

Embodiment Construction

[0030] exist figure 1 A vessel 1 is shown in , equipped with a first docking member in the form of a pinion 3 . Basically, the pinion 3 is a gear that can be actuated, for example rotated by a motor. A rotatable pinion 3 is used to establish the state of connection with the offshore structure.

[0031] figure 2 The vessel 1 is shown approaching the offshore structure 4 . In this embodiment the offshore structure 4 is a monopile, which serves as a foundation for the wind turbine. However, the docking device can be used with other offshore structures such as casings, gravity foundations, drilling rigs or even semi-submersible structures.

[0032] The offshore structure 4 is provided with a second docking member 5 formed like a ladder. Each of said second abutment parts 5 comprises two parallel struts 6 connected by transverse struts 7 . Such as figure 2 As can be seen in , several second docking components 5 are arranged along the circumferential direction of the offsho...

Abstract

A docking device for facilitating a transfer between a vessel (1) and an offshore structure (4), whereby the docking device comprises a first docking component mounted on said vessel (1) and a second docking component (5) mounted on said offshore structure (4) whereby the first and second docking components (5) are connectable such that bow (2) or stern of the vessel (1) can be elevated in the connected state.

Description

technical field [0001] The present invention relates to a docking device for facilitating transfer between a vessel and an offshore structure. Background technique [0002] Offshore structures such as monopiles, casing structures or floating structures are increasingly used in offshore wind farms with increasing demand. For the erection, maintenance and repair of such offshore wind farms, there is a need for safe, reliable and cost-effective transfer of personnel and lightweight equipment between vessels and offshore structures. [0003] Currently, transfers of personnel and equipment are performed by various vessel types and transfer systems. These range from transfers via small, fast rescue boats to dedicated vessels equipped with motion compensated access platforms. [0004] Transfer vessels with so-called smart bow fenders are known to facilitate the push of the transfer vessel towards, for example, a bumper protector on a transition piece of a wind turbine installatio...
