Abstract
Abstract An oil interceptor or separator vessel for use on board ship, having an outlet oil line with an outlet oil weir therein and an outlet water line with an outlet water weir therein, and wherein the weirs are mounted adjacent one another and at a position above the main part of the separator vessel, the edge of the oil weir being at a higher level than the edge of the water weir. When the separator vessel is mounted on board a ship, at least the weirs are oriented whereby the edges of the weirs lie in substantially a port-starboard direction.
