Abstract

A series of model tests were carried out to study the process of oil leakage from the damaged oil tanker with the rupture on the side and underwater, which has the same size but different height. And some essential data were analyzed in different cases, such as the duration, the velocity and the volume of leakage. Result shows that the overall process is composed of two different stages. The difference of pressure and density between the water and oil is the driven force in these two stages. While the effect of rupture hole height plays an important role in the overall process,not only the duration of different stage but also the volume of oil leakage from the oil tank. Finally, the dynamic mechanism and characters are illustrated by studying the effect of rupturehole height on the oil leakage process in different stages by using the model test.

Key words： oil tanker; damaged underwater hold; rupture hole height; oil leak; leakage mechanism
