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.

Abstract: The invention relates to a method (300) of estimation of a probability of damage caused by sloshing of a liquid load during an operation to transfer said liquid load from a first floating structure (1) to a second floating structure (40), the first floating structure (1) and the second floating structure (40) being associated with one another during said transfer operation so that the first floating structure (1) and the second floating structure (40) are oriented with a common bearing (99). The method includes steps (307) of estimating a probability of damage to at least one tank of at least one of said first and second floating structures (1, 40) and (308) of supplying information to a user as a function of the probability of damage estimated in this way.
