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 mooring device (100) includes a method for operation. The mooring device (100) has an attachment unit (101) including a contact surface (102) for contacting a surface of an object (201) to be attached and at least one magnet for generating a magnetic field through the contact surface (102) to the object (201), a regulator (104) for adjusting the magnetic field generated by the at least one magnet, a telescopic arm (105) pivotally attached to the attachment unit (101), a first hydraulic cylinder (106) and a second hydraulic cylinder (107) attached to the telescopic arm (105), and a monitor for monitoring linear displacements of the first hydraulic cylinder (106) and the second hydraulic cylinder (107). The regulator (104) is configured, based on the linear displacements, to adjust the magnetic field so that an attachment point on the surface of the object (201) can be changed.

There is disclosed a mooring device (10) comprising an attachment unit (66) for mooring of a floating unit (110) to a floating or non-floating structure (125). The mooring device (10) comprises a first mooring arm (12) and a second mooring arm (20) for transferring and/or absorbing forces and energy that arises when the floating unit (110) moves relative to the floating or non-floating structure. There is also disclosed a floating unit and a floating or non-floating structure comprising one or more such mooring devices (10).

An electro-permanent magnet (EPM) for an electromagnetic mooring system (EMS) includes a low coercivity magnet surrounded by a reversible coil, and one or more high coercivity magnets surrounding the low coercivity magnet and the reversible coil. The reversible coil switches polarity of the low coercivity magnet to null the stronger, one or more high coercivity magnets. The nulling of the stronger, one or more high coercivity magnets allows for the EMS to connect and disconnect to an adjacent apparatus.
