Kawasaki Kisen Kaisha Ltd (K Line) and Namura Shipbuilding Co Ltd have received joint Approval in Principle (AIP) for the concept design of an LNG-fuelled ore carrier from DNV GL.
A registered brand of Namura Shipyard, the WOZMAX (‘West’ ‘OZ’ ‘MAX’) design is claimed to be the optimum size of vessel that can call at the main West Australian iron ore loading ports.
Based on the second-generation WOZMAX, K Line said that work on this joint project for the development of an LNG-fuelled ore carrier has complied with both environmental and actual operational requirements as follows:
EEDI is the number of grams of CO2 emitted when carrying 1t of cargo for 1 mile, and 30% reduction is required in phase 3, compared with the reference value, which is the average of vessels built between 1999 and 2008.
In addition to LNG fuel conversion, the partners 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.
K Line said it is continuously attempting to obtain greater efficiency in its operations as well as further reduction of CO2 emissions and environmental pollutants in accordance with K Line Environmental Vision 2050, its long-term environmental management vision.
“This system is considered as one of the efficient systems that will help us achieve our goals by 2050,” the Japanese carrier stated. “Environmental concern with greenhouse gas emission effect is growing and K Line will, based on K Line Environmental Vision 2050, encourage less environmental load from marine transport by operating ships that are highly energy efficient and which contribute to conservation of the global environment.”
