Shaft Generator On Ship

About this product

Introduction

The Shaft Generator On Ship is a marine power system that integrates directly with a vessel's propulsion shaft to convert mechanical energy into electrical power. Unlike conventional auxiliary generators that consume fuel independently, this system harnesses the main engine's output during normal navigation and captures rotational energy to supply onboard electrical loads. Installed between the main engine and propeller or via a gearbox power to take it off, the unit operates across varying shaft speeds through advanced power conversion technology. Engineered for durability in harsh marine environments, it delivers electrical output with minimal added complexity, making it suitable for both new builds and retrofit projects across a wide range of commercial vessels.

Features

Shaft-Driven Power Generation: Directly connected to the ship's main engine shaft, eliminating the need for additional independent drive motors, reducing equipment volume and energy loss, and improving the overall energy utilization rate of the ship. Marine Environment Adaptability: Adopts corrosion-resistant materials and sealed structure, resisting corrosion from seawater, humidity and salt spray, and adapting to severe working conditions such as ship vibration, tilting and high and low temperatures. Stable & Reliable Operation: Optimized shaft connection design, ensuring stable transmission between the main engine shaft and the generator, with small vibration and low noise, and capable of continuous power generation during long-term ship navigation. Flexible Power Regulation: Equipped with advanced power conversion and regulation system, which can adjust the power generation output according to the ship's power demand, matching the load change of navigation equipment and living facilities, and ensuring stable voltage and frequency.

Benefit

This technology saves a lot of fuel, usually five to ten percent during sea passage, by using power from the main engine instead of running auxiliary generators. Running auxiliary engines less extends maintenance intervals, lowers lubricating oil use, and reduces wear on power plant parts. The system improves electrical reliability by delivering a stable power supply independent of cargo operations, ensuring continuous power for navigation, refrigeration, and hotel systems. From a regulatory perspective, the ship's shaft generator helps comply with EEXI and CII requirements by enhancing the vessel's carbon intensity rating.The modular design simplifies installation and minimizes downtime during the retrofit, delivering a rapid return on investment through the combined fuel and maintenance savings.

Conclusion

The system offers a proven and cost effective solution for shipowners seeking to optimize fuel efficiency and reduce operational burdens. It converts existing propulsion power into valuable electrical energy while cutting another engine runtime and associated maintenance costs. As environmental regulations tighten, this technology provides a practical pathway to enhanced vessel competitiveness. Investing in the Shaft Generator On Ship delivers measurable economic and environmental returns throughout the full cycle of vessel operation.
