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.
Claims16
A method of controlling a roll motion of a ship, through at least one stabilizing fin, characterized in that it comprises the following steps:
- a. starting a movement of the stabilizing fin when the roll motion starts;
- b. controlling an angular rate of the stabilizing fin directly in response to a roll rate of the ship;
- c. ending the movement of the stabilizing fin when the roll motion ends.
A method of controlling at least one of a roll, pitch, or heave motion of a ship, through at least one stabilizing fin, characterized in that it comprises the following steps:
- a. starting a movement of the stabilizing fin when the roll, pitch, or heave motion starts;
- b. controlling an angular rate of the stabilizing fin directly in response to a roll, pitch, or heave rate of the ship;
- c. ending the movement of the stabilizing fin when the roll, pitch, or heave motion ends.
