How the MasterTrack 588 works
The Mastertrack588 includes a stainless steel cage with a sealed door. The chief engineer possesses the key and when locked, the system cannot be tampered with. It ensures that only water with an oil content of less than 15 ppm is discharged overboard.
The bilge water from the oily water separator is pumped through the system and analyzed by an oil content meter. A flow switch secures that there is flow through the oil content meter and a flow meter measures the accumulated volume discharge overboard.
The three way valve will immediately redirect the bilge water back to the bilge water holding tank if
- the door is opened
- the oil content exceeds the legal limit of 15 parts per million (PPM)
- the flow to the oil content meter is lost
All components inside the system are connected to a digital recorder mounted in the engine control room, which typically logs every 10 minutes: the oil content, three way valve position, flow through oil content meter, accumulated discharged volume, rejected volume, door position, alarms together with the vessel’s geographical position (GPS) and time.
To maintain an overview the accumulated values are shown on the main screen of the Mastertrack588 (resettable): the total amount of discharge water in addition to the total amount of rejected water.
All data is logged and stored in an encrypted format. It can be presented to any official body, e.g. Port State Control, Coast Guard, and Vetting or Classification Society Officials to provide the necessary proof of compliance.
