Abstract: A system and method for automated handling, transferring and storing conventional cargo storage containers on a cargo ship wherein the containers are stored in a multi-tier cell system and are manipulated by powered transfer units which are selectively moveable along an intersecting overhead track system such that containers may be simultaneously retrieved from, moved or placed within any of the cells of the ship. The transfer units are equipped both with hoists, which control spreader beams which are selectively secured to the cargo containers, and guide stabilizers, which prevent undesirable movement of the cargo containers when they are elevated above the cell structures such that the containers may be manipulated even during rough sea conditions such that the system is essentially continuously operable as a floating supply distribution system.

The quick release system can be in tension to apply a compressive force between the grillage system and the topsides until the quick release system is released.

Generally, the transport element is provided at an attachment region of a tower, or the like, where the tower would attach to a support, such as a jacket. There is also described apparatus for allowing for transport of a wind turbine structure, comprising a clamp. In some cases, the apparatus is also configured so as to modify the effective centre of gravity of an associated structure, and/or the effective centre of inertia of an associated structure.

Abstract: The invention relates to a standardized platform (1) equipped with two beams (11, 11?) which are transverse relative to its front end and its rear end. The transverse beams extend beyond the lateral edges of the platform, such that the ends of these beams can receive slings (24a-24d) which allow the assembly to be secured to hoisting and handling means of containers. It is thus possible to transport goods (21) which are both wider and longer than a standardized platform (1), on this platform (1). The goods can therefore be handled and loaded by means of hoisting and handling means for containers, i.e. for a cost which is reduced in comparison with oversized transport.
