The Whitebox® is installed between the Oily Water Separator (OWS) and overboard valve and is a protection system to prevent illegal discharges of bilge water from machinery spaces on-board ships. The Whitebox contains all vital monitoring and control equipment for the overboard discharge in a locked cabinet connected to the vessels GPS. All vital data such as Oil content, valve positions, flow through the oil content monitor and overboard flow, door open/closed, vessel’s position and time is recorded in a digital recorder. The Whitebox can also monitor sewage overboard pump or STP running if connected.The data is stored in a secure digital format in the recorder and the history can be presented on the display or on a separate computer. That enables the crew to present the discharge data to USCG, Vetting, Class or port state and can prove that the operations have been compliant. 

The number of fines for illegal or accidental discharges of bilge water keeps increasing. The Whitebox provides protection for the crew, the company and the cargo owner as it presents the evidence of the vessels activities regarding discharge. Apart from logging it also helps prevent illegal discharge from occurring.

On the 2017 edition the oil content meter can be operated without opening the doors and the port state control can also be performed with closed doors as the recirculation handle is available from outside.

Marinfloc can produce operational reports from the recorder data displaying discharged volumes, average oil content and OWS performance on monthly charts for environmental declaration.

The Whitebox can be connected to the Marinfloc Ocean Guardian that can close the three way valve in the Whitebox when the vessel passes the 12 nautical mile line anywhere in the world.

The Whitebox can also be used to monitor the discharge from the clean drains such as drains from the AC system or air cooler drains from the main engine. This type of water is generally very clean and could be pumped directly overboard which is approved by most classification societies. However as it may contain oil we recommend to discharge it through the Whitebox and if oil is present it will be directed to the bilge water tank for treatment by the OWS. This will greatly reduce the daily bilge water yield and the operation time and running costs of the OWS.
