CompactClean BWMS

SEPTEMBER 11, 2017 — Nørresundby, Denmark, based DESMI Ocean Guard A/S has launched a new ballast water management system (BWMS) called CompactClean that, it says, “sets new standards for small footprint, reliable performance, and certainty of meeting both International and U.S. discharge standards.”

The CompactClean BWMS is currently undergoing type approval testing according to both IMO and USCG requirements, under the surveillance of Lloyd’s Register. It is expected that type approval certificates will be obtained by around May 2018.

“With the CompactClean system we have managed to develop a system that can treat ballast water everywhere in the world and meet both IMO and U.S. Coast Guard standards, says DESMI Ocean Guard CEO Rasmus Folsø. “The system is free of any troubling operational limitations and can treat water independent of its salinity (fresh, brackish, and marine water) and temperature, and can operate at full flow in the vast majority of ports around the world. It is important to underline that this performance is global and the system does not include any special modes or similar that needs to be applied during discharge of ballast water in U.S; territory. For DESMI it has been important to provide the shipping industry with a solution that works globally without any special interference of the crew, and which can be installed very easily without relocating other equipment.”

The CompactClean BWMS consists of an automatic backflushing filter, a UV unit, valves, sensors, and controls. The UV unit has a unique and patent pending shape that is the result of hundreds of state of the art numerical simulations. This shape ensures optimum dosage of the UV to all organisms in the water, and the result is a system that can meet even strict USCG type approval requirements.

Additionally, the system includes many features that are important to daily operation. These include automatic generation of PDF reports that document all the performed ballast water treatment, in a format that is suitable for submission to local port state authorities and others. Another feature is inclusion of a pump that can be used as a stripping pump under ballast stripping operations, thus solving one of the main problems in ballast water management system installations today.
