Abstract: A skidding system for skidding a heavy load over a deck of a vessel includes a hydraulic cylinder cooperates with a skid shoe and the load to be displaced with respect to a skid rail along a line of displacement. The hydraulic cylinder extends to displace the load when the skid shoe is locked with respect to the skid rail. A skid shoe displacement device moves the shoe with respect to the rail in the same direction along the line of displacement when the shoe is unlocked from the rail. A first releasable coupling couples a piston rod to the load. A second releasable couples a cylinder body to the skid shoe. A third releasable coupling couples the cylinder body to the load to be displaced with respect to the skid rail along the line of displacement, while a fourth couples the piston rod to the skid shoe.

Abstract: The invention relates to a skidding system for an offshore installation or vessel, such as an offshore wind turbine installation ship, comprising at least one set of rails, and one or more carriages for supporting loads and moving the loads along the rails, e.g. from a storage position to an operating position and/or vice versa. At least one of the carriages is adaptable to different loads.

Abstract: A vessel for e.g. well intervention or deep sea lowering, comprises a moon pool and a hoisting arrangement for lowering and retrieving items, in particular equipment, tools, and/or supplies or modules comprising the same, through the moon pool, into respectively from the sea and onto respectively from the seabed or an installation on the seabed. The vessel further comprises one or more guides for laterally retaining items inside the moon pool, preferably at least two guides positioned on opposite sides of the moon pool.
