Shipboard testing conducted on a US-flagged Aframax has opened the way for a ballast water management system (BWMS) manufacturer to try for US Coast Guard (USCG) type-approval.
De Nora completed the testing of its Balpure BWMS in November 2017 while the tanker was operating on the US west coast in the regulated waters of California and Alaska. The tanker was in its normal trading pattern and was ballasting and deballasting with the Balpure system on a regular basis.
With the application, De Nora has become the ninth manufacturer to apply for US Coast Guard type-approval. Although reports suggest that its application was submitted shortly after it completed its tests in late 2017, the USCG website confirms its application was received a few days ago (3 March).
Lloyd’s Register has acted as De Nora’s Independent Laboratory and De Nora had initially expected to submit its application by the end of 2017. Don Stephen, managing director, De Nora Water Technologies UK, told Tamker Shipping & Trade that although shipboard testing was finished in November, "to secure the paperwork needed for submission we needed to wait for the test labs to release the final report." Nonetheless, he believes its turnaround time has been shorter than some other manufacturers’.
His comments followed a statement issued earlier (6 March) in which he expressed "every confidence that Balpure will achieve USCG type-approval." He also looked forward “to working with new customers [and] continuing to work side-by-side with the large fleet of ships already actively ballasting and deballasting with De Nora Balpure technology."
The De Nora statement recalled that the company is the originator and patent holder of electrochlorination disinfection of ballast water through the slipstream method. It also mentioned that Balpure "has been previously identified by the US EPA Science Advisory Board as one of three systems that demonstrated the ability to meet a standard 10 times more stringent than the IMO D-2 standard."
