Nippon Yusen (NYK) recently announced that it will jointly cooperate with MTI and Japan Shipbuilding Joint Shipyard (JMU) to analyze the status of ship propellers and develop a high-efficiency propeller to improve fuel efficiency and reduce carbon dioxide emissions.
The company said that it is expected that the new high-efficiency propeller will reduce carbon dioxide emissions by 1.2%. This new type of propeller is expected to be installed on two new container ships delivered in 2019.
Nippon Yusen stated that the actual operation of the propeller was analyzed by observing the phenomenon of cavitation produced by the propeller and measuring the flow rate around the propeller. The company stated that its project partners analyzed the status of the propellers operating on ocean-going vessels and confirmed that the probability of matching simulated data with actual conditions is high. The company will use a high degree of simulation to restore the reality and optimize the propeller design to improve fuel efficiency.
The three companies involved in the project believe that if it is possible to accurately monitor the operating conditions of propellers installed on an ocean-going vessel and then design a propeller based on the optimized shape of the monitoring results, the environmental load of the vessel may be further reduced.
The three companies analyzed the condition of the propellers that were operating on ocean carriers. The analysis report can be found in The Naval Architect, a magazine published by the British Society of Naval Ship Engineers in February 2018. The three companies will also publish their analysis report at the hullpic meeting held in the UK in mid-March.
Nippon Yusen stated that the three companies will continue to cooperate and use their expertise to achieve sustainable development opportunities through the provision and operation of high-performance ships.
