Canada’s Trojan Marinex has submitted a type-approval application to the US Coast Guard, the first system to do so, according to consultancy firm Mouawad Consulting, which “worked closely with the Trojan Technologies team during this process,” it said in a discussion forum on the LinkedIn social media site in March.
The company itself had not confirmed that application to BWTT as this issue went to press in late April, but its website has long proclaimed that the company has “carefully and deliberately implemented a strategy to put ourselves in a good position to be one of the first ballast water treatment system suppliers to obtain USCG type-approval.”
Its product suite obtained IMO type-approval from DNV GL on behalf of the Norwegian Maritime Directorate in March 2014, followed in August by acceptance from the USCG as an alternate management system (AMS).

Its system uses filtration and UV radiation to kill organisms in ballast water, prompting one consultant on the LinkedIn forum to question whether it would be capable of meeting the USCG standard of less than 10 living organisms of 50µm or less per m3 of water.
In its online FAQs, the manufacturer addresses the question of whether its system meets USCG discharge standards, saying: “We performed our IMO certification process to the rigorous standards required by the USCG, supporting our goal of achieving USCG type-approval in 2015.” BWTT
