The Trojan Marinex ballast water treatment (BWT) product suite has obtained IMO type approval already in March this year. It[ds_preview] was granted from classification society Det Norske Veritas (meanwhile DNV GL) on behalf of the Norwegian Maritime Directorate.
»We are the largest UV company in the world, and are committed to providing pioneering water treatment technologies that meet the highest standards and help protect and preserve our environment,« said Marvin DeVries, President of Trojan Technologies. »The IMO type-approved Trojan Marinex product suite is a reflection of our forward-looking commitment to our customers. We performed our certification process, in every way possible, to the rigorous standards required by the United States Coast Guard (USCG), supporting our goal of achieving US type approval this year. Testing was successfully completed in the most challenging conditions. This dispels the myth that UV cannot be used in the poorest of water qualities and gives vessel owners the confidence and
reassurance they deserve, knowing that their operations will be unencumbered,« he explained.
Rather than focusing on being among the first to get IMO type approval and testing to minimum standards, focus was instead put on the continual refinement of the ballast water treatment technology and a robust testing protocol. Testing was conducted under the supervision of DNV GL, who is now certified as an Independent Lab (IL) by the USCG, in accordance with United States Environmental Protection Agency (USEPA) Environmental Technology Verification (ETV) Ballast Water Protocol. The ETV protocol is a key testing requirement for systems to obtain USCG type approval.
Land-based testing was completed at the DHI Maritime Technology Evaluation Facility in Hundested, Denmark, and shipboard testing was completed on board the »Training Ship Golden Bear« (TSGB) – both are now part of DNV GL’s network of subcontractors approved by the USCG for testing BWT systems. The testing was conducted up to 1250m3/h to verify the efficacy of the system at higher flow rates, meeting the requirements of IMO circular BWM.2/Circ.33 (Guidance on the Scaling of Ballast Water Management Systems).
In addition to the rigorous certification and testing methodologies employed, the Trojan Marinex BWT system is differentiated in that custom-designed filtration and UV is integrated into in a single, compact unit. Trojan UV Solo Lamp technology was utilized to ensure the lowest installed power draw of other systems in the market, the company pointed out. This extremely low power draw means that larger vessels, such as bulkers and tankers, can effectively choose a UV-based solution.
