OSG will retrofit the proprietary slipstream electrochlorination BWTS on four LR1s in the first half of 2017.
De Nora will supply its BALPURE BP3000-C system, which can treat up to 3,000 cu m per hour of ballast water, for installation on the ‘Overseas Goldmar’, ‘Overseas Silvermar’, ‘Overseas Rubymar’ and ‘Overseas Rosemar’.
This is OSG’s second planned installation of the BALPURE system, having entered into a contract with De Nora to retrofit two MRs, the ‘Overseas Milos’ and ‘Overseas Athens’, earlier this year.
Lawrence Quinn, De Nora Water Technologies CEO, commented: “This order on behalf of OSG marks our first confirmed order following ratification of the IMO’s Ballast Water Management Convention last month, and the start of what we expect to be a swift ramp-up in the retrofit market for BWTS. An existing customer that operates a majority US flagged fleet trading under the Jones Act, this deal exemplifies the partnerships we have built and the industry confidence in our offering.
”De Nora is poised and ready to help our customers meet compliance effectively and for the long-term. The BALPURE system is IMO Type Approved with USCG AMS acceptance and is currently progressing through both land-based and shipboard testing for compliance with US Coast Guard (USCG) ballast water management legislation. Moreover, it has been rigorously tested in commercial use and we are extremely confident that the BALPURE system will meet the world’s most stringent ballast water standards,” he said.
De Nora is the patent holder of the slipstream electrochlorination design concept used in BALPURE systems. BALPURE has also been identified by the US EPA Science Advisory Board (SAB) as one of only three systems able to meet a standard 10 times more stringent than the IMO D-2 standard.
The company said that it expected to complete the testing and apply for USCG type approval in the first quarter of 2017.
