DOMESTIC VESSELS
Domestic Vessels
Supporting Safe Voyages for Ferries, Domestic Cargo Vessels, and Specialised Vessels
Domestic vessels play a vital role in sustaining Japan’s logistics network, requiring both safety and operational efficiency. We are not only enhancing propulsion efficiency, but also advancing initiatives aimed at improving safety and reducing crew workload. Our participation in the development of automated berthing/leaving technologies is helping unlock new possibilities for the operation of domestic vessels.
Fixed pitch propellers
High-performance fixed pitch propellers with a design that balances efficiency, vibration control, and strength, ensuring both reliability and performance.
ECO-Cap
A newly designed fin-equipped propeller cap that reduces energy loss caused by hub vortexes.
Ultimate Rudder Bulb
This advanced rudder bulb places the bulb as close as possible to the propeller, minimizing hub vortexes and improving propeller-rudder interaction.
Neighbor Duct
An innovative stern duct that generates forward thrust and reduces hull resistance.
Monster Package
An optimized package that combines multiple Nakashima energy-saving devices to further boost propulsion performance.
ZERO
The Air Lubrication System (ALS) sends microbubbles under the hull to reduce frictional resistance and improve fuel efficiency.
Composite Stator
A GFRP (glass fiber-reinforced plastic) energy-saving device co-developed with Fluid Techno.
Shafting Systems
We offer optimal shafting system designs, from the shaft body to surrounding components, tailored to customer requirements.
Jet Thruster
A compact, fully azimuthal jet-type thruster developed specifically for domestic cargo ships, based on user feedback.
Controllable Pitch Propeller
Controllable pitch propellers that allow vessels to adjust speed without changing engine RPM by altering the blade angle. Suitable for tankers, ferries, fishing vessels, tugboats, and more.
Azimuth Thruster
Nakashima’s azimuth thrusters rotate 360 degrees, offering excellent maneuverability and energy-saving performance.
Rudder
A wide selection of rudders optimized for a balance between course-keeping and turning performance.
NASCA
NASCA is a real-time vessel operation monitoring system accessible via smartphone or tablet.
Tunnel Thrusters
Compact yet powerful tunnel thrusters with specially developed blade shapes to improve maneuverability.
CFRP Propeller
Propellers made of Carbon Fiber Reinforced Plastic (CFRP), offering high efficiency and low vibration.
Shaft Horsepower Meter
A shaft power meter is an instrument used to measure the transmitted horsepower from the main engine to the propeller by detecting the torsion (twist) of the rotating shaft.
