AFTER SUPPORT &
MAINTENANCE
One-Stop System from Design to After-Support
To deliver peace of mind to customers around the world, Nakashima
Propeller has established a global service and support network.
Retrofit & Fuel Efficiency Improvement Solutions
We offer retrofit services by replacing propellers with optimized models based on actual vessel operation. We also support recycling of scrapped propellers and provide consulting to improve propulsion performance for better fuel efficiency on vessels in service.
Propeller Repair and Maintenance Services
We offer repair of damaged propellers, edge cutting to restore efficiency lost due to aging, and polishing/cleaning services.
Integrated Design for Optimal Propulsion Performance
Using a large-scale CFD system, we design optimal propellers that satisfy requirements for efficiency, cavitation, and strength. The stern area is holistically designed with the propeller as the core.
Package Solutions of Propulsion Equipment and Energy-Saving Devices
We provide packaged solutions combining propellers with energy-saving devices to improve overall propulsion performance.
Monitoring and Analysis of Propeller Operation
We monitor propeller condition after delivery and provide visibility into fuel efficiency. Solutions are proposed in response to aging and wear.

PROPOSAL
Recommendations from a Propulsion
Equipment Manufacturer
[Edge Cutting for Improved Operational Performance]
"Has your engine been running torque-rich since the ship was built?"
"Are you considering installing energy-saving devices?"
For shipowners with such concerns, edge cutting of the propeller can lead to further improvements in operating conditions. Please feel free to consult with us.
[Regular Thruster Maintenance]
Some components of thrusters, such as sealing systems and O-rings, use rubber materials, which generally have a service life of 6 to 8 years. Bearings used in rotating parts also have limited lifespans. If the thruster becomes inoperable due to poor maintenance, additional costs such as tugboat fees and labor expenses may arise. We urge you to recognize the importance of regular inspections and maintenance to ensure continued safe operation in the future.
