DESMI Ocean Guard has announced that a new configuration of its well-known CompactClean ballast water management system (BWMS) has been approved by both the US Coast Guard and the Danish Maritime Authority
DEMSI has produced a high volume ballast water treatment system for clients operating bulk carriers. Named the CompactClean Bulker ballast water treatment system, it adds to the existing CompactClean product lines. It is designed for higher flow rates during deballast, solving one of the main operational issues faced by bulk carriers complying with ballast water regulations.
Some vessel types, in particular bulk carriers, often need to discharge ballast water faster than they conduct ballast water uptake. This is related to the speed of cargo loading, which is for some cargo types and ports much faster than unloading.
With the CompactClean Bulker ballast water treatment system, ballast water uptake and discharge speeds match this to optimise vessel operations.
Typical ballast water management systems have been approved with just one max flow rate, which is the same during ballast and deballast operations, but now DESMI Ocean Guard has introduced a tailor-made solution.
The 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 deballast, the need for a higher deballast flow rate can be accommodated by selecting a larger UV unit than filter.
DESMI Ocean Guard chief executive Rasmus Folsø said, “A recent example of DESMI Ocean Guard providing 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 m3 /hour and a UV unit with max flow rate of 1,500 m3 /hour, the vessels have been able to continue their current operation, conducting ballast water uptake at 750 m3 /hour and ballast water discharge at 1,500 m3 /hour.”
Mr Folsø added, “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 this is fully approved. And with the issuance of an updated USCG type-approval on 5 January, this CompactClean solution is now approved globally”.
