Abstract:
1. A buoy provided for ascending or descending in water from an initial submerged position, which buoy comprises a buoyancy element positioned at an upper portion of the buoy in the ascending direction, a storing structure for an elongated member positioned below the buoyancy element in the ascending direction, the storing structure comprising a drum which is non-rotatably fixed relative to the buoyancy element, wherein one end of the elongated member is connected to the buoy and the other end of the elongated member is connected to an object submerged in the water, wherein the buoyancy element is arranged such that a torque, caused by the water acting directly on a surface of the buoyancy element when the buoy is ascending in the water, causes a rotation of the buoy around its central axis, the elongated member thereby being paid out while the buoy is ascending in the water.
