DESMI has developed two new ballast water management systems (BWMS) covering bulker solutions and ships sailing in IMO waters only
Ballast water treatment system provider DESMI has launched two very specific BWMS. The CompactClean Bulker, is, as the name suggests, specifically designed to meet the needs of the bulk carrier sector. The CompactClean OptIMO is designed to meet only IMO standards, with a reduced UV array and lower power consumption. It can still meet the US waters standard, but at a reduced flowrate.
These new systems join the DESMI portfolio of BWMS alongside the well-known CompactClean BWMS.
DESMI Ocean Guard chief executive Rasmus Folsø said, “Not all ships are engaged in global trade but rather in regional or domestic trade, and as such, a significant part of the world fleet will never, or only rarely, enter US waters. Such vessels can benefit from a BWMS solution that is optimised to IMO requirements and not US Coast Guard requirements, and this is exactly what we have developed with our new CompactClean OptIMO BWMS.”
He added, “This BWMS has lower power consumption and fewer UV lamps and thus provides both capex and opex savings, as well as an even smaller footprint than the market-leading footprint of CompactClean BWMS.”
Vessels equipped with an OptIMO BWMS are not excluded from US waters. “The OptIMO BWMS meets the USCG requirements and can be operated in a US compliance mode, which however involves a smaller maximum flowrate, but does make it suitable for operation in US waters when needed,” said Mr Folsø.
The second newly introduced DESMI BWMS is the CompactClean Bulker, which is a BWMS optimised for the operation of bulk carriers or other vessel types, where discharge of ballast water is performed at an increased flowrate. “With the bulker solution we can tailor-make a BWMS for our customers which will allow one flowrate during ballast, and another and higher flowrate during de-ballast. As the filter is only applied during ballast operation it can be downsized to match the lower flow during ballast, and therefore CompactClean Bulker grants the customer a capex reduction, as well as an opex reduction in case the filter internals need replacement during the life of the BWMS,” said Mr Folsø.
