Trojan Technologies has announced that it has obtained the International Maritime Organization[ds_preview] (IMO) Type Approval from classification society DNV GL for the Trojan Marinex ballast water treatment system (BWTS) on behalf of the Norwegian Maritime Directorate.
According to the company the testings were successfully completed in the most challenging conditions. The focus was on the continual refinement of the ballast water treatment technology and on a robust testing protocol. The testing was conducted under the supervision of DNV GL, who is now certified as an Independent Lab by the United States Coast Guard (USCG), in accordance with United States Environmental Protection Agency’s Environmental Tech-nology Verification (ETV) Ballast Water Protocol. The ETV protocol is a key testing requirement for systems to obtain USCG Type Approval. The land-based testing was completed at the DHI Maritime Technology Evaluation Facility in Hundested, Denmark. It was conducted up to 1250 m3/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).
The shipboard testing was completed on board the training ship »Golden Bear«. According to Trojan Technologies the BWTS has been tested and approved to the lowest UV transmittance value (poor water quality) in the industry under full flow conditions, meeting the re-quirements of IMO Circular BWM.2/Circ.43c (Guidance for Administrations on the Procedure for Evaluating an Application for Type Approval of a Ballast Water Management System). Further-more, the system has been tested and approved in all three salinity ranges – brackish, fresh and marine. According to the company the Trojan Marinex BWTS is differentiated in that custom-designed filtration and UV is integrated into a sin-gle, compact unit.
