US Coast Guard (USCG) type-approvals of ballast water management systems (BWMS) now number 10 following last week’s certificate issued to Wärtsilä Marine Solutions for its Aquarius EC system.
It was awarded on 30 August, nearly five months after its application was submitted on 9 April.
It uses an electrolysis-based technology and Wärtsilä Marine Solutions also offers a UV-based version. No application has yet been submitted for that system but a statement from the company today (3 September) said that it expects to receive USCG type-approval for that equipment by the end of the year.
It completed testing for that version on 25 June and, in July, it said it was waiting for final input from its independent laboratory, the class society DNV GL, before completing its documentation and submitting its application. Its BWMS sales director Craig Patrick said at the time that once it obtained type-approval for both products, it would be “the first supplier to provide both technologies as IMO and USCG type-approved systems.” BWTT has asked Mr Patrick for an update on progress towards its application.
In today’s statement, Wärtsilä Marine Solutions vice president for processing solutions Timo Koponen said that, because it offers two technologies, “we are uniquely able to provide impartial advice to owners and operators regarding the most suitable system for their particular needs.”
Its Aquarius EC can treat ballast water flow rates from 250-4,000 m3/h using a two-stage process of filtration and electrochlorination. Its neutralisation effectiveness is continuously monitored, the company said. Its type-approval certificate, which lists operational limitations, is available via the link below.
• A further 10 USCG type-approval applications are pending. A full list and other related information is available online from the USG’s Marine Safety Center.
