Abstract: A process is described for controlling the roll motion of a ship, with null or low ship speed, through at least one stabilizing fin. The process comprises the following steps: starting the movement of the stabilizing fin when the roll motion starts; impressing a motion law of the stabilizing fin depending on the roll rate; and ending the movement of the stabilizing fin when the roll motion ends.

Abstract: A method is described for attenuating the oscillation of a ship, which includes a controller of a drive adapted to move at least one fin to allow stabilizing the ship, when the ship is at zero speed, anchored, wherein the motion of such at least one fin comprises an initial acceleration step, an intermediate step at constant speed and a final deceleration step. In the initial acceleration step, such at least one fin can start from a first angular position, while in the final deceleration step, such at least one fin can reach a second angular position corresponding to minimum or null values of effects opposite to those of the acceleration and constant speed steps of such at least one fin to allow maximizing the useful roll moment generated by such at least one fin.

Abstract: A system (1) is described for determining offsets (?) of measuring instruments, in particular of measures with a null or constant mean value, composed of first processing means (3) adapted to compute, from at least one value of a measuring signal (S) deriving from an instantaneous measure performed by at least one measuring instrument or a sensor, at least one offset value (?) of such signal (S); and second processing means (5) adapted to subtract such offset value (?) from the value of the instantaneous measure signal (S) to obtain a corrected measure value (S??) of such signal S. A process is also described for determining offsets (?) of measuring instruments, in particular of measures with a null or constant mean value.
