DESMI Ocean Guard’s CompactClean Bulker solution

Nørresundby, Denmark-headquartered DESMI Ocean Guard A/S reports that a new configuration of its well-known CompactClean BWMS has been approved by both the U.S. Coast Guard and the Danish Maritime Authority. Named CompactClean Bulker, it is additional product line to the existing CompactClean product lines that is designed for higher flow rates during deballasting, solving one of the main operational issues faced by bulk carriers in complying with ballast water regulations.

Some vessel types, in particular bulk carriers, often experience a need to be able to discharge ballast water faster than the time they spend on ballast water uptake. This is related to the speed of cargo loading, which is for some cargo types and ports much faster than the speed with which they can unload cargo. The ballast water uptake and discharge speeds need to match this in order not to become obstacles to the operation of the vessel.

So far, typical ballast water management systems have been approved with just one maximum flow rate, which is the same during ballasting and deballasting operations. DESMI Ocean Guard’s CompactClean Bulker solution enables the CompactClean system to be configured with any combination of its approved filters and UV units and as the filter is by-passed during deballasting. the need for higher deballasting flow rate can be accommodated by selecting a higher rated UV unit than filter.

“A recent example of DESMI Ocean Guard being able to provide a solution to a customer that solves this issue is for a series of bulk carriers. These vessels operate today with cargo loading being twice as fast as cargo offloading. By selecting a CompactClean BWMS with a filter with max flow rate of 750 cu.m/h and a UV unit with max flow rate of 1500 cu.m/h, the vessels have been able to continue their current operation, conducting ballast water uptake at 750 cu.m/h and ballast water discharge at 1500 cubic meters per hour,” says Rasmus Folsø, CEO of DESMI Ocean Guard. “It may sound simple, but such solutions can make a world of difference for the customer, and therefore, we are ready to go the extra mile to ensure that this is fully approved. And with the issuance of an updated USCG Type Approval on January 5, this CompactClean solution is now approved globally.”

DESMI Ocean Guard says that the new addition to its offerings strengthens its position as a market leader, which during 2020 was further cemented with the highest order intake recorded in a year, despite the COVID-19 pandemic which led to postponement of a large number of BWMS retrofit projects. The first weeks of 2021 have started well with several significant orders and frame agreements, and the company is confident that 2021 will present another year with increasing market shares and new records in order intake and turnover.
