Abstract: A system and method for the estimation of a sloshing response of a sealed and thermally insulating tank for transporting liquefied gas. A statistical model is trained using a supervised machine learning method on a set of test data that may include sea test data, the statistical model being capable of estimating a sloshing response of the tank depending on a tank fill level and a current sea state, and optionally at least one of a draught, speed or course of the vessel. The statistical model trained in this manner is used to estimate a sloshing response of a sealed and thermally insulating tank for transporting liquefied gas. In an alternative embodiment, the statistical model estimates the sloshing response from a tank fill level and a current sea state, and optionally from at least one of a draught, speed or course of the vessel.
