Joint Approval in Principle (AIP) for New Concept Design of LNG-fuelled Ore Carrier
Japanese shipping major K Line has, together with Namura Shipbuilding, received an Approval in Principle (AIP) for the concept design of an LNG-fuelled ore carrier from DNV GL.
The parties said that work on this joint project complied with both environmental and actual operation requirements as follows, based on Namura Shipyard’s second generation WOZMAX, an optimum size of vessel that can call main West Australian iron ore loading ports.
The new design would keep almost the same deadweight and normal service speed as WOZMAX, retain enough endurance for round-trip between Singapore and Brazil in gas fuel mode, arranging the LNG tanks in center section of hull, as well as achieve EEDI phase 3 by means of primary fuel changes to LNG, K Line said.
In addition to LNG fuel conversion, the parties studied the possibility of it being combined with shaft generator, binary cycle power generation system and lithium battery so as to further reduce CO2 emissions and confirmed that this system can achieve an additional 4% reduction of fuel oil consumption.
