| 摘要 |
The present invention relates to a system adapted for control of buoyancy of a vessel, which vessel is a catamaran (CAT), which catamaran is adapted to operate in a first CAT mode, which catamaran is adapted to operate in a second SWATH mode, which catamaran comprises a plurality of ballast tanks, which ballast tanks are mostly empty in the first CAT mode, which ballast tanks are mostly water-filled in the second SWATH mode. It is the object of the pending patent application invention to increase the stability of a vessel in both CAT mode and in SWATH mode. The object of the invention can be achieved if the first CAT mode lightship weight is distributed towards mid ship, and in the second SWATH mode is water ballast is distributed towards the ends of vessel. Hereby a vessel designed to operate in two different modes of operation can be achieved where a first CAT mode is preferred for transportation of the vessel and which is highly effective efficient because the vessel is operating at a relatively high level, and in the CAT mode, the water line follows the two hulls of the vessel. |
