ABSTRACT:
A dockside system for the collection and disposal of bilge water, waste oil and the like is described for continuously evacuating waste liquids from waterborne vessels (16, 18) into a shore vacuum tank (24) and for simultaneously and automatically separating oil and water from the waste liquid. A continuous regulated vacuum is applied near the top of the vacuum tank (24) for sucking waste liquid, such as bilge water and oil, through tubes (30, 33, 82) into the tank. The tubes have manually operated on/off valves (34) at outer end portions thereof which are operated at the bilges of the waterborne vessels. Water and oil are separated in the tank and each is respectively and automatically pumped to a water and oil receiving station (28 and 26) by means of a water outlet (88) located near the bottom of the tank, an oil outlet (92) located a relatively small distance above the water outlet, an oil/water interface sensor (98) positioned vertically between the water and oil outlets, an upper liquid level sensor (96) in the tank positioned substantially above the water and oil outlets and a lower liquid level sensor (100) in the tank positioned below the upper liquid level sensor but above the water and oil outlets.
