The Ministry of Land, Infrastructure, Transport and Tourism (MLIT), through its “Support for Technology Development from Marine Vessels for Curtailing CO2” project, has decided to subsidize through fiscal 2009 the below three projects that NYK is currently working on in tandem with other companies for future technology development.
1: Experiment to confirm the effectiveness of technology to reduce frictional resistance created by a large, shallow-draft vessel equipped with a twin screw motor
Research conducted by Mitsubishi Heavy Industries Ltd. and NYK with expected cooperation from the Monohakobi Technology Institute and NYK-Hinode Line Ltd.
This experiment will confirm the frictional-resistance reduction created by air lubrication on a module vessel (to be completed in 2010). By supplying air to a vessel’s bottom, the air lubrication reduces frictional resistance between the seawater and the vessel’s bottom. For the first time, this technology will be installed on commercial vessels as a permanent fixture, and it is expected to result in a reduction of CO2 emissionsby approximately 10 percent.
2:R&D of vessels’ operational performance as they become larger
Research conducted by NYK, the Monohakobi Technology Institute, and Japan Maritime Science Inc.
Most Japanese car carriers are less than 200 meters in length. By making vessels larger, the amount of CO2 emission per car (amount of CO2 emitted for transporting a single car) can be reduced. In this project, which uses a simulator and other technologies, tests will be conducted on risk-avoidance and operational performance(performance to avoid collisions) for car carriers longer than 200 meters in length. Based on this research, the project will propose requisite technologies for large vessels so as to achieve the same level of operational performance as conventional vessels.
3: Development of international navigation control system
Research conducted by NYK and the Monohakobi Technology Institute (MTI).
Efficient navigation of vessels is a prerequisite for curtailing CO2 emissions. In this project, NYK and MTI have started joint development of a worldwide time-reservation system for berth window and canal passage. The introduction of an international port control system will enable vessels to further reduce their time at ports and to navigate at lower speeds. This project will also make use of international services when the system is implemented, and propose future roles for international navigation controls.
In addition to the subsidy from MLIT, these projects will be implemented as part of the “R&D for Reducing Greenhouse Gas in International Maritime Affairs” program, which is being jointly carried out by the Japan Ship Technology Research Association and the Nippon Foundation.
The NYK Group remains committed to pursuing technological innovations to suppress global warming.
