Norway's IMS group AS announced it has signed a purchase agreement with the OceanSaver Trustee to acquire the ballast water management system (BWMS). Last week OceanSaver filed a petition to liquidate with Norway's Register of Bankruptcies last week, shortly after losing an arbitration against filter maker Bollfilter Nordic and had to pay both sides’ a sum that has not been made public. OceanSaver’s BWMS was one of the firsts to secure US Coast Guard type-approval on 2016, but blamed the IMO's MEPC 71 decision to defer installation deadlines by two years as having a major impact on the market for retrofitting ballast treatment systems. In addition, ship newbuilding activity continues to be low and the combination has led to significant downward pressure on equipment prices. OceanSaver has sold approximately 200 ballast water treatment systems.
