This specification covers the construction, operation, and safety requirements for a shipboard oil pollution abatement system (OPAS) that processes oily waste and allows selective suction from all oily waste holding tanks, waste oil, dirty oil, and drain tanks and the bilges of all oily water generating spaces for operation within the U.S. Contiguous Zone as excepted by local regulatory authorities. This specification covers the entire system from the point of entering the system until the oil-water mixture is treated and discharged overboard. It includes minimizing oily waste generation, the oily waste holding tank, the oil-water separation device, the control system, feed and recirculation pump(s), a secondary treatment device, and an automatic stopping device.

1.1 This specification covers a shipboard oil pollution abatement system (OPAS) that processes oily waste and allows selective suction from all oily waste holding tanks, waste oil, dirty oil, and drain tanks and the bilges of all oily water generating spaces for operation within the U.S. Contiguous Zone as excepted by local regulatory authorities.

1.1.1 This specification covers the system from the point of entering the system until the oil-water mixture is treated and discharged overboard.

1.1.2 This includes minimizing oily waste generation, the oily waste holding tank, the oil-water separation device, the control system, feed and recirculation pump(s), a secondary treatment device, and an automatic stopping device capable of detecting 15 ppm oil in the waste stream.

1.1.3 Fig. 1 provides a general system schematic to utilize for system configuration.
