Method for controlling the filling levels of tanks

A computer-implemented management system of the filling levels of tanks, said tanks being arranged in a ship and connected in such a way as to allow liquid to be transferred between said tanks, the system comprising means for:

• providing an initial state defining initial filling levels of the tanks,
• providing at least one environmental parameter defining environmental data of the ship, said at least one environmental parameter comprising a wind sea height and/or a swell height,
• determining a target state defining final filling levels of said tanks,
• determining a liquid transfer scenario, the transfer scenario defining one or more flows of liquid to be transferred between the tanks during a transfer period in order to shift from the initial state to the target state of the tanks,
• calculating a probability of damage to the tanks as a function of successive filling levels of the tanks during the transfer period and of said at least one environmental parameter, the probability of damage to the tanks defining a probability that at least one tank will be damaged during the course of the transfer scenario, and
• generating a series of instructions intended to transfer the liquid between the tanks in accordance with said transfer scenario in response to the probability of damage to the tanks satisfying an acceptance criterion.
