At SinoShaft, we specialize in providing cutting-edge energy-saving solutions for the marine industry. Our Energy Saving Devices (ESD) are engineered to optimize ship performance, reduce fuel consumption, and help operators meet the increasingly stringent environmental regulations.

Our comprehensive ESD solutions include key technologies such as Pre-swirl Fairing (PSF), Boss Cap Fin (BCF), Rudder Bulb (RB), High-Efficiency Propellers (HEP), and Propeller Trimming (PT). These devices work together to enhance hydrodynamic efficiency, reduce wake losses, and improve overall propulsion performance.

A standout example of our ESD retrofit project involves a bulk carrier at the Zhoushan Zhongtian Shipyard. By implementing a combination of PSF, BCF, RB, and PT, the vessel achieved a remarkable 8.10% fuel saving during sea trials, equating to an annual fuel saving of 248.7 tons. The return on investment (ROI) was calculated at just 1.2 years, underscoring the effectiveness and cost-efficiency of SinoShaft’s energy-saving solutions.

Our ESD solutions are designed for both newbuilds and retrofits, providing substantial energy savings and improving operational efficiency for vessels operating on international routes. The integration of our energy-saving devices supports compliance with the Energy Efficiency Existing Ship Index (EEXI) and the Carbon Intensity Indicator (CII), ensuring long-term sustainability for shipowners and operators worldwide.

SinoShaft Marine Technology Co., Ltd. has long been known for its expertise in marine propulsion system maintenance and stern tube seal services. We are now focused on expanding our capabilities to include advanced Energy Saving Devices (ESDs) and Shaft Generator Systems.
