Abstract
A storage tank 1 is divided into oil and ballast water chambers 3, 4 by an elastic partition membrane 2. To prevent the membrane from blocking the oil and water intake/discharge ports 5, 6 during the final stages of loading or unloading, the internal edges and corners of the tank are chamfered by apertured partition plates, supported wire mesh screens or the like, and the intake/discharge ports communicate with the spaces defined behind such plates or screens.
