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.
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.
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.
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.
