Finnish technology group Wartsila has become the first company to win US coast guard (USCG) approval for a second ballast water management system (BWMS).
Its Aquarius UV kit has been granted approval, following earlier clearance for the Wartsila Aquarius EC system.
“Wartsila’s dual technology offering provides the broadest range of BWMS solutions for fleet wide regulatory compliance," said Craig Patrick, general manager of sales, water and waste at Wartsila Marine.
"This means that owners can be sure of having the most appropriate system for their particular needs from the same premium support supplier."
Aquarius UV uses ultra-violet irradiation, while Aquarius EC features electro-chlorination.
