DNV GL LogoEcochlor and DNV GL announced today DNV GL Type Approval on behalf of Norway of the Ecochlor Ballast Water Treatment System (BWTS). In addition to serving as Ecochlor’s Independent Laboratory for US Coast Guard (USCG) Type Approval, DNV GL simultaneously evaluated and approved the Ecochlor System under DNV GL rules and the BWM Convention.

Martin Olofsson, DNV GL Business Development Manager for BWMS type approval testing said, “DNV GL is very pleased to have worked with Ecochlor for both the USCG and the DNV GL Type Approval. It has been a challenging, although rewarding, process, as Ecochlor was the first system using a chemical injection treatment technology to be evaluated. Also, many of the issues were a new experience for the USCG. Due to Ecochlor’s dedicated, and highly technically competent staff, the challenges we faced were handled in a most professional manner.”

“DNV GL has been very thorough in overseeing testing of the Ecochlor System.” said Tom Perlich, President of Ecochlor. “Throughout this process we have been honoured to work with the staff at DNV GL and feel that these recent collaborative efforts for the two type approvals will greatly benefit shipowners installing BWTS on the vessels that are represented by DNV GL as their class society.”

“Through the DNV GL Type Approval project, we have used this opportunity to fine-tune our rules concerning the safe installation of the Ecochlor BWTS on ships. The DNV GL sub-laboratory Golden Bear Facility in San Francisco has done both the land-based and shipboard testing and the results have confirmed the biological efficacy of this system. DNV GL used these same test results and documentation to submit and issue a BWTS type approval certificate on behalf of Norway. We congratulate Ecochlor for achieving these great milestones of being the first chemical treatment USCG Type Approved system and for their IMO/Norway Type Approval,” commented Ingrid Sigvaldsen, DNV GL Project Manager.

With its USCG Type Approval certificate, Ecochlor stands alone as the first approved treatment system produced by a US manufacturer; the only approved chemical injection treatment technology; the only system suitable for installation on US flagged tankers with high flow rates; the only approved BWTS that does not require re-treatment or neutralization on discharge; and, a treatment system with almost twice the flow capacity of any other approved USCG Type Approved technology.
