USCG approval for new DESMI BWMS

CompactClean Bulker is designed for higher flowrates during de-ballast, solving one of the main operational issues faced by bulk carriers which often need to discharge ballast water faster than the time they spend on ballast water uptake.

“Bulk carriers operate today with cargo loading being twice as fast as cargo offloading,” explained Rasmus Folsø, chief executive of DESMI Ocean Guard. “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,” he added.

Typical ballast water management systems have been approved with just one maximum flowrate, which is the same during ballast and de-ballast operations, but now DESMI Ocean Guard has introduced a tailor-made solution.

This enables the CompactClean system to be configured with any combination of its approved filters and UV units and, as the filter is bypassed during de-ballast, the need for higher de-ballast flowrate can be accommodated by selecting a larger UV unit than filter.
