NYK signed a business alliance agreement with Nakashima Propeller Co., Ltd. and Fluid Techno Co., Ltd. to test the effects of energy-saving devices that boost vessel fuel efficiency by improving water flow generated at the ship's aft end, select optimal combinations of those energy-saving devices, and install them on existing ships.

NYK intends to minimise greenhouse gas (GHG) emissions from current vessels over the next three years by installing energy-saving devices on about fifty dry bulk carriers.

As wave resistance and water-flow turbulence diminish, ships can generally operate with less energy; thus, the maritime and shipbuilding industries have created numerous energy-saving measures. Although the effects of individual energy-saving devices have been verified by the marine equipment manufacturer that created each device, the ideal combination of several energy-saving devices and the verification of their synergistic effects have not been exhaustively studied.

To address this issue, NYK will partner with Nakashima Propeller, a maker of ship propellers and energy-saving technologies, and Fluid Techno, a ship design business with fluid analysis technology.

This corporate alliance is a pioneering effort in the marine industry, as the three companies will collaborate to determine the optimal combination of different energy-saving gadgets by combining their respective expertise and strengths. Through this endeavour, a one to eight per cent increase in fuel economy and a reduction in vessel greenhouse gas emissions are anticipated.

The "NYK Group ESG Story" was published in February 2021 and intends to further incorporate ESG into the company's management strategy and encourage commercial actions that contribute to attaining the sustainable development goals (SDGs). In March of this year, NYK published the updated "NYK Group ESG Story 2022," which introduces initiatives for integrating ESG into the Group's management strategies outlined in the "NYK Group ESG Story" and provides a partial explanation of the Group's long-term sustainable growth strategy.

In the process of achieving the long-term goal of net-zero greenhouse gas emissions by 2050, both research and development of zero-emission boats and the improvement of the fuel efficiency of vessels that use heavy oil as fuel play a crucial role. To push ESG management vigorously, the NYK Group will support the creation of new value as a provider of sustainable solutions.
