Nippon Yusen Kabushiki Kaisha (NYK) has signed a business alliance agreement with Nakashima Propeller Co., Ltd (Nakashima Propeller) and Fluid Techno Co., Ltd. (Fluid Techno) to reduce emissions on the company’s dry bulk carriers.
The deal will install energy-saving devices to improve water flow generated at the aft-end of ships.
NYK will collaborate with Nakashima Propeller, a marine equipment manufacturer that develops and sells ship propellers as well as energy-saving devices, and Fluid Techno, a ship design company with fluid analysis technology.
The three companies will jointly work on the best mix of multiple energy-saving devices.

From the deal NYK aims to reduce greenhouse gas (GHG) emissions from existing vessels by installing energy-saving devices on around 50 dry bulk carriers over the next three years.
Improvements of fuel efficiency by 1 to 8 per cent and reduction of vessel GHG emissions are expected.
“Ships can generally operate with less energy as wave resistance and water-flow turbulence decrease, so various energy-saving devices have been developed in marine and shipbuilding industries,” NYK wrote.
“Although the effects of individual energy-saving devices have been verified by the marine equipment manufacturer that developed each device, an optimal combination of multiple energy-saving devices and verification of their synergistic effects have not been thoroughly researched.”
