De Nora applies for USCG BWTS type approval

Mar 09 2018

De Nora has submitted an application to the US Coast Guard (USCG) for type approval for its patented BALPURE ballast water treatment system (BWTS).

This application was made shortly after completion of testing in late 2017.


Independently verified by Lloyd’s Register, the results of all shipboard, land-based, and environmental testing, plus documentation, engineering design and final drawings associated with BALPURE are now with the USCG, De Nora said.


Don Stephen, managing director, De Nora Water Technologies UK, commented: “Submission for USCG type-approval illustrates De Nora’s ongoing, long-term commitment to the marine industry. As a global, multi-national with 90 years’ pedigree, De Nora has the scale and solidity to endure any bumps in the road to enforcement of the Ballast Water Management Convention. Working in conjunction with our partner, Lloyd’s Register and – in the early stages – with consultant, Jad Mouawad, we have every confidence that BALPURE will achieve USCG type-approval and look forward to announcing that key landmark in due course.


"We look forward to working with new customers on the road to compliance, as well as continuing to work side by side with the large fleet of ships already actively ballasting and deballasting with De Nora BALPURE technology,” he added.


Completed in November 2017, the shipboard testing was conducted on a US-flagged Aframax operating on the US west coast in the regulated waters of California and Alaska. The tanker was in her normal trading pattern and was ballasting and deballasting with the BALPURE system on a regular basis.
