Patent ID: 8479674

Claim:
System for the active and passive stabilization of a vessel ( 10 ), which vessel ( 10 ) is provided with a plurality of independent separate tanks ( 11 a - d ) to provide buoyancy and/or ballast, which separate tanks ( 11 a - d ) are provided with openings ( 12 a - d ) in the bottom, which openings ( 12 a - d ) are facing the medium the vessel ( 10 ) is floating in, which separate tanks ( 11 a - d ) are independent of each other, wherein the plurality of separate tanks ( 11 a - d ) are separately and independently controllable of each other and are arranged in such a way that they have an extension so that a main part of the separate independent controllable tanks ( 11 a - d ) extends above a fluid level the vessel ( 10 ) is floating in, and a minor part of the separate independent controllable tanks ( 11 a - d ) extends below the fluid level the vessel ( 10 ) is floating in, as the vessel ( 10 ) is floating in normal conditions without any loads, wherein each of the plurality of separate independent controllable tanks is provided with a vacuum/pressure ( 13 a - d ) compressor configured for large changes of pressure in an associated tank, and a valve configured for small changes of pressure in an associated tank for providing positive or negative pressure in associated separate independent controllable tanks ( 11 a - d ) for the removal or supply of fluid, respectively, by directly adding positive pressure to the interior of associated separate independent controllable tanks ( 11 a - d ) to provide the vessel ( 10 ) with buoyancy, or directly adding negative pressure to the interior of associated separate independent controllable tanks ( 11 a - d ) to provide the vessel ( 10 ) with load independent of the vessel movements, which vacuum/pressure ( 13 a - d ) compressors and valves are independently controlled to counteract the effects of external forces on the movements of the vessel ( 10 ).
