摘要: 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.

摘要: A method, apparatus, and computer program product are present for analyzing voyage efficiency. Historical data for a completed voyage of a ship is obtained. A baseline voyage solution for a completed voyage is generated with a software application executing on a processor unit using a model of the ship and the historical data. The baseline voyage solution is compared to an actual voyage solution used for the completed voyage to form a comparison.
