A floating body to which an aquatic or marine facility is installed or which is connected to a lower part of the aquatic or marine facility to hold the aquatic or marine facility on water or the sea is proposed. The floating body may include a main floating body which floats on water or the sea by using buoyancy, and a magnet provided on a first vertical side of the main floating body. The floating body may also include a coupling member provided on an opposite vertical side of the main floating body by corresponding to a magnet of another floating body such that the coupling member is coupled thereto, and a mooring line installed on a part of the main floating body to moor and hold the main floating body on water or the sea.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle and other autonomous vehicles can be transported to the location of use by a ferry vehicle thereby conserving vehicle systems and resources and expanding the vehicle utility.

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 recovery device for an unmanned underwater vehicle (UUV) includes a first recovery component arranged on an unmanned ship and a second recovery component arranged on the UUV. Two magnets are provided on an end of the first recovery component and an end of the second recovery component which are opposite to each other, respectively. A first cable of the unmanned ship is provided on an end of the first recovery component away from the magnet, and a second cable is provided on an end of the second recovery component away from the magnet. A thruster is provided on a side of the first recovery component. The UUV is recovered using the unmanned ship through the recovery components connected to the cables, which allows the locating and navigation errors to a large extent.
