The likely significance of imposed marine motion on full scale process vessels containing oil and water is illustrated by considering the natural periods of gas/liquid and oil/water interfaces. Experimental and numerical modelling studies of the effects of imposed motion on gas/liquid and oil/water interfaces in a 1.78 m long rectangular model vessel are then described. Aspects studied include the effectiveness of solid and perforated baffles in suppressing the amplitude of disturbances at the two interfaces. Numerical modelling using a volume of fluid technique gave good agreement with amplitude measurements in the unbaffled vessel. This modelling technique has also been used to predict interface profiles and velocity fields in oil and water layers with and without a perforated baffle.
