De Nora has revealed that land-based and ship-board testing of their BALPURE electrochlorination- based ballast water treatment system (BWTS) for United States Coast Guard (USCG) Type Approval application is underway at the NSF Independent Laboratory at Maritime Environmental Resource Centre (MERC) in Baltimore, United States.
Under the land-based testing, the BALPURE BWTS will be tested almost every week in different water salinities and with different filters. The shipboard test is being conducted by a MERC specialist onboard a vessel that has had BALPURE installed for a number of years, which is traversing the west coast of the US over a period of six months.
The conclusion of these two testing periods will complete the four document packs that De Nora will submit to the USCG to apply for type approval for its BWTS.
De Nora has already completed both engineering design and environmental testing elements of the submission to the USCG.
Lawrence Quinn, CEO, De Nora Water Technologies commented: “Getting both of these sets of testing underway ensures we are on track with our approvals timeline for full type approval from class societies, IMO and the USCG in 2017. We anticipate land-based testing to be completed with multiple filter suppliers and in all three salinities required this year with shipboard testing to follow shortly after, dependent on the weather conditions and its effect on the organisms present in the water along the route of the vessel the tests are being conducted on.”
The BWTS has already secured IMO Type-Approval as well as type-approval from Lloyd’s Register, ABS and Bureau Veritas. To date, De Nora BALPURE® has been selected for 55 new build LNG vessels and tankers and has recently been chosen for the retrofit of seven vessels.
