Clean Bilge Monitoring

Discover our intelligent clean bilge monitoring system CBM-LINK

efficient bilge management

The complete bilge system by RWO

Our contribution to a fully digitalized system maintenance that will make the operation of water treatment plants on ships much more efficient, transparent, safe and environmentally friendly.

CBM-LINK, the intelligent clean bilge monitoring system, helps you realize the full potential for optimizing water treatment onboard ships. The system is compromised of two systems working together seamlessly:  

CBM acts as the final control mechanism before bilge water is discharged. The compact system has a 3-way valve, which allows the inflow of treated bilge water and water that is normally uncontaminated, such as condensate from air conditioners. The system independently monitors whether, as prescribed by IMO Resolution MEPC 107 (49) for particularly sensitive sea areas (PSSA), maximum oil content of 0, 5 or 15 ppm in the water being discharged is complied with and automatically transfers it either directly overboard or to the bilge water tank for further treatment. This significantly reduces the quantity being treated by the bilge separator. Additional assurance is provided by a 2-point measurement of oil content. All modes of operation, valve positions, system configurations, ppm levels and OMD information can be visualised and read via digital and analogue interfaces. 

The system is tamper-proof and prevents the deliberate or unintentional unlawful discharge of contaminated water. Ship operators can thus avoid horrendous fines.

LINK is a software system which provides detailed information about the operation of the system as well as the composition of the bilge water. The information can be visualised in real time, enabling timely adjustment of system modes. Connected to the ship's communication system, the system is able to access GPS coordinates. Based on the data collected during the test phase, future features will be developed to further optimise operation of the system. In 2019, for example, it should be possible for LINK to independently determine when filter changes are necessary, making planning for maintenance work considerably more efficient and minimising operating costs and downtime.
