Peace of mind with secure and monitored overboard discharge. Protects the owner and the crew from non-compliant discharges. Everything recorded and securely documented. Monitor your discharge to ensure you fulfill valid regulations.
The Marinfloc Whitebox® – a failsafe overboard discharge monitoring and control unit. Positioned between the oily water separator and the overboard valve, the Whitebox® is designed with precision to prevent non-compliant bilge water discharge, ensuring your operations remain within the regulatory bounds of MEPC.107(49).
The Whitebox® guarantees consistent monitoring of all vital discharge data and is seamlessly integrated with the vessel’s GPS. This ensures that your operations are transparent and accountable with recorded data on oil content, valve settings and flow metrics.
Enjoy enhanced confidence in your discharge operations, safeguarding your crew and vessel from potential disputes. The digital recorder meticulously stores all critical data, from vessel position and time to door status, ensuring every detail is accurately logged for future reference. Let the Whitebox® bring peacefulness to your maritime operations, ensuring the highest standards of environmental compliance.

The WhiteBox® system is a fail-safe system for the overboard discharge of water. It is designed so that no water with an oil content above the set limit can accidentally be pumped overboard. The oily water separator or the bilge water tank discharge pump feeds water through the WhiteBox® system. An adequate flow of water is continuously directed to the oil content meter by the differential pressure valve. The sample is measured by the oil content meter after being directed through the flow switch.
The purpose of the flow switch is to secure that no bilge water can be discharged overboard without first being measured by the oil content meter. The flow overboard, the oil content, the position of the three way valve, status oil content meter is activated, the status of the system (on/off), the time and the ship’s GPS position (optional) will be logged and stored on the recorder or on an external memory card depending on configuration.
The three-way valve will be in over-board position as long as the following criteria are fulfilled:
• The oil content meter reading is below the set oil content level.
• The rinse water valve is not activated by the pushbutton.
• The recorder value is below set oil content level.
• The WhiteBox® door is closed.
• There is a sufficient flow through the flow switch.
• Discharge is enabled by the Bridge control or Ocean Guardian (if fitted).
If one or more of the above criteria is not fulfilled, the three-way valve will switch to return position. The recorder will still log the oil content, three-way valve position, sufficient flow through oil content monitor, GMT time and the ship’s GPS position (if fitted) but not the flow, as no processed bilge water is directed overboard.
If the alarm is connected, the oil content meter will give an alarm to the engine control room after a preset period of time (0-9 minutes) if the oil content is above the set oil content limit.
Take control of the Port state control
The development of the Marinfloc WhiteBox® is the culmination of more than 25 years of innovation, with a focus on practicality and user-friendliness at its core. Understanding the importance of ease and efficiency for port state inspections, Marinfloc has intentionally designed the WhiteBox® with features that address these needs directly.
One such feature is the recirculation valve, thoughtfully placed for external access, making it more convenient for inspectors to perform checks without the hassle of opening the unit. This design choice not only simplifies the inspection process but also highlights Marinfloc’s commitment to creating user-friendly solutions.
The implementation of an accessible test program via the Oil Content Meter panel on the unit’s door further exemplifies the thoughtfulness put into the WhiteBox®.
By enabling inspectors to run tests quickly and efficiently, Marinfloc demonstrates its understanding of the operational pressures faced by maritime professionals.
Marinfloc’s dedication to refining and evolving the WhiteBox® over a quarter of a century is evident in its design and functionality. This long-term commitment to improvement, guided by feedback and the realworld experiences of maritime users, ensures that the WhiteBox® stands as a paragon of reliability and userfocused innovation in marine wastewater management.
Through features like the external recirculation valve, Marinfloc not only meets the current needs of the maritime industry but also anticipates future requirements, ensuring compliance and simplifying processes for all stakeholders involved.
