PropellingVision 2026

Optimising propulsion performance

"Propelling" is the Nakashima's new brand concept that highlights whole ship propulsion performance. Nakashima Propeller Co., Ltd. will have its 100-year anniversary in 2026. Propellers are largely responsible for the propulsion performance of a ship, and they can be optimised by taking the figure of the whole ship into account. A ship's optimal state is found when it is viewed from the propeller, the centre of propulsive functions. With this fresh perspective, Nakashima seeks to offer a full range of services catering to each ship's entire life cycle while achieving fuel efficiency to reduce the burden on the environment. Nakashima works to contribute to the world, beyond the realm of its industry.



Optimum design integration tailored to conserve energy

After the implementation of the energy efficiency design index (EEDI) for environmental conservation, we began development of a propeller with the smallest blade area. We offer products that maximise propulsion efficiency with energy-saving devices installed in front of and behind the propeller.


Tamashima factory has the cutting edge equipment and skilled craftsmen.

We have introduced the latest facilities at our Tamashima factory, including high-precision CNC blade milling machines, high-technology propeller overturning machines and internet-of-things (IoT) sensors, all of which improve efficiency and ensure safety at the plant. Nakashima Propeller combines the latest facilities and the technique of a superior craftsman to produce highly accurate and optimised propellers for customers.

Lifecycle propulsion

Perfect aftercare to maintain propulsion power

A current focus of our corporate development is on after-sales service and repairs that ensure efficient propulsion performance at sea. We also consult with clients about propeller replacement and the propulsion performance of energy-saving devices as a ship's operating conditions change, and we can propose the most suitable solutions for a particular application.


New-generation propellers

We have also developed next-generation propellers that use lightweight carbon-fibre composite materials. In 2014, we succeeded in installing propellers with blades made of CFRP (carbon fibre reinforced plastics) on commercial ships for the world's first time. Nakashima Propeller continues to explore new generation propellers that allow higher efficiency and reduction of vibration.

High-Performance Rudders

For optimal manoeuverability

Becker Marine Systems, our esteemed partner from Germany, stands at the forefront of high-performance rudder development, emphasizing maximum efficiency. These rudders not only excel in hydrodynamic performance, resulting in reduced fuel consumption, but also simplify maintenance through a design with fewer moving parts.

Energy Saving Devices

Pre-Swirl ― Improving the propeller efficiency

The innovation continues with Becker Marine Systems' Pre-Swirl Energy Saving Devices, most notably the Becker Mewis Duct® and the Becker Twisted Fin®. These devices go beyond propeller enhancement; they redefine efficiency standards. The Becker Mewis Duct® harmonizes flow distribution, creating a pre-swirl that minimises rotational losses. This ingenious technology not only generates additional thrust, but also reduces vessel drag by minimising flow separation.


Future going together with world's vessels

Since 1926, Nakashima has improved the ability of propellers to improve outcomes for 'sellers, buyers and the business world'. We will continue to challenge optimizing propulsion performance for people, ocean and future world while focusing on ship's lifecycle.
