The loads due to internal fluid motions are believed to be cause of severe damages occurring on the walls of tanks on board. Even if a general description of sloshing loads in terms of dynamic and impact pressures on the walls is available, a quantification of such pressures in large scale is still difficult. This paper reports the results of an experimental campaign on board of a ship during a voyage between Italy and South Africa. The results of the surveys performed by means of pressure transducers placed on the tank walls and of strain gauges in a close position are presented together with ship motions surveys obtained by means of a gyro-platform. Additional acceleration transducer are also placed on the weather deck. Such results, together with those available from a previous, analogous, campaign, allow to state actual values of sloshing loads (peak value and duration) for both dynamic and impact pressures and to relate them to ship motions.
