Abstract
A method is described for providing an alert when the motion of a ship indicates a potential of sloshing damage from liquid cargo being transported by the ship. The method includes calculating, with a processing device, a natural period for the tanks holding the liquid cargo based on the configuration and fill levels of the tanks, receiving, at the processing device, data describing the actual or predicted motion of the ship with respect to three orthogonal axes, determining, with the processing device, a proximity of the natural period of the tanks to a period defined by the actual or predicted motion of the ship, and providing an alert to a user if the proximity in periods is within a threshold value.
