DESMI RECEIVES IMO AND USCG BULKER BWMS APPROVAL

DESMI RECEIVES IMO AND USCG BULKER BWMS APPROVAL

Friday, January 22, 2021 

Desmi Ocean Guard's new configuration of its CompactClean ballast water management system (BWMS), named CompactClean Bulker, has been approved by both the US Coast Guard and the Danish Maritime Authority.

This is an additional product line to the existing CompactClean, designed for higher flowrates during de-ballasting, solving one of the main operational issues faced by Bulk Carriers 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 BWMS have been approved with just one max flowrate, which is the same during ballast and de-ballast operations, but this newly type approved 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 de-ballast the need for higher de-ballast flowrate can be accommodated by selecting a larger 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 flowrate of 750 m3/h and a UV unit with max flowrate of 1500 m3/h, the vessels have been able to continue their current operation, conducting ballast water uptake at 750 m3/h and ballast water discharge at 1500 m3/h”, said Rasmus Folsø, CEO, 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 5th 2021, this CompactClean solution is now approved globally.”
