The present invention relates to a vessel 1 comprising a floating body, 2, 3 on the top of which there are a superstructure 7, 8, 25, 26, 35, 36 and a deck as well as ballast means for varying the buoyancy of the floating body 2, 3 and for moving the floating body 2, 3, relative to the surface of the water in which the floating body is floating, between a high position with the top of the floating body 2, 3 above the water surface and a low position with the top of the floating body 2, 3 below the water surface and the superstructure 7, 8, 25, 26, 35, 36 partially above the water surface, wherein the deck is at the level of the top of the floating body 2, 3. What is achieved according to the invention is that the vessel has a surface area that cuts through the water only on columns protruding partially above the water. As a result the vessel is very little influenced by being struck by waves. Thus it is possible to position loads on the columns and to remove loads from the columns in a controlled manner. |
