DESMI CompactClean BWMS completes land-based testing for IMO, USCG

(AALBORG, Denmark) — DESMI Ocean Guard A/S has announced that all the required land-based testing of the CompactClean ballast water management system has been successfully completed. The testing was performed in accordance with both International Maritime Organization (IMO) and U.S. Coast Guard requirements and paves the way for issue of both IMO and USCG type-approval certificates later this year.

The testing includes 15 land-based tests, five in each of the three salinities required: fresh water, brackish water, and marine water. Results of the testing confirm that the system meets the stringent discharge requirements without any special operating mode to be employed in U.S. territory and without any minimum holding time to be observed between ballast water uptake and discharge.

“We are especially pleased that no less than seven land-based tests performed in different salinities and at various levels of UV transmission of the water have been successfully completed with the shortest holding time allowed for land-based testing. This means that there is no required minimum holding time for the CompactClean system. Requirement for minimum holding times for type-approved BWMS is one of the main issues that ship operators are facing within ballast water treatment today, and we are happy to be able to provide a solution with our CompactClean system,” said Rasmus Folso, CEO of DESMI Ocean Guard A/S.

The CompactClean BWMS consists of an automatic backflushing filter, a UV unit, valves, sensors, and controls. The UV unit has a patent-pending shape that is the result of hundreds of numerical simulations. This shape ensures optimum dosage of the UV to all organisms in the water, and the result is a system that meets even USCG type-approval requirements. Furthermore, the system includes many features that are of importance to the daily operation. One example is automatic generation of reports that document all the performed ballast water treatment, in a format that is suitable for submission to local port authorities and others. Another example is that the system includes a pump that can be used as a stripping pump under ballast stripping operations, thus solving one of the main problems for ballast water management system installations today.

The CompactClean BWMS is currently undergoing type-approval testing according to both IMO and USCG requirements, under the surveillance of Lloyd’s Register. For more information, visit www.desmioceanguard.com.
