OceanSaver has entered the Japanese market with a major ballast water treatment contract for four open hatch bulk carriers being built by Japan’s Oshima Shipbuilding Ltd for Gearbulk. The 72,000dwt Open Hatch Bulk Carriers are being built to DNV class and each vessel will be fitted with a 1,200m3/h type approved Mark II OceanSaver system. The first two systems will be commissioned in 2012 and will incorporate OceanSaver’s second generation design, engineered for reliability, low maintenance requirements and low power consumption.
