Abstract

A shipboard system 200 to process contaminated water and exchange commands and data with a remote facility. The shipboard system includes a separation system 10, controller 202, and a communication unit 204. The separation system includes a separator 16, oil accumulator 18, coalescer 20, and a pump 24. The controller 202 is coupled to the separation system 10 and is operable to acquire data relating to processing of contaminated water and can utilize commands received by the communication system 204 to permit remote control of the separation system. The communication unit transmits the data via satellite or other wireless transmission to a command center 212. The shipboard system can also include a global position system which can be used by the controller to inhibit the discharge of contaminated liquids when the ship is in protected waters.

Claims

a separation system having a housing that includes an inlet and first and second outlets, said inlet being located internally within the vessel to receive bilge water and/or ballast water contained onboard the vessel, said separation system further including a pump coupled to said housing to provide a flow of the received water through said housing from said inlet to said first outlet, said separation system being operable to process the water flowing through said housing and supply separated contaminants to said second outlet;

a data acquisition interface coupled to said separation system, said interface being operable to acquire data relating to processing of the bilge and/or ballast water by said separation system; and

a communication unit coupled to said interface to receive the data acquired by said interface, said communication unit including an antenna and being operable to provide wireless transmission of the data to a remote facility via said antenna.

2. A system as defined in claim 1, wherein said housing comprises a separator having a plurality of flow restrictors spaced within said housing between said inlet and said first outlet.

3. A system as defined in claim 2, wherein said housing is disposed at an inclined angle with said inlet being located at a lower end of said housing and said first and second outlets being located at an upper end of said housing.

4. A system as defined in claim 2, wherein said separation system further comprises a coalescer having a housing that includes an inlet and first and second outlets, wherein said inlet of said coalescer is coupled to said first outlet of said separator and said pump is coupled to said separator and said coalescer to circulate the water through said separator and then through said coalescer.

5. A system as defined in claim 4, further comprising an accumulator coupled to said second outlets of said separator and said coalescer.

6. A system as defined in claim 1, wherein said housing comprises a coalescer having a coalescing element disposed in said housing between said inlet and said first outlet.

7. A system as defined in claim 1, wherein said separation system includes a sensor coupled to said interface to provide said interface with a signal indicative of a measurable parameter of said separation system, and wherein said interface includes a microprocessor operable under program control to process the signal as digital data and to provide said communication-unit with the digital data for transmission to the remote facility.

8. A system as defined in claim 7, wherein said microprocessor is operable under program control to provide an alert signal via said communication-unit when the digital data crosses an alarm limit.

9.
