S-Shaft (PTO) installation project
Adopting the half-half Shaft Generator type (split-type), the S-Shaft PTO installation is a feasible option for both Retrofit and New Building projects.
The S-Shaft generator is being configured based on vessel’s electrical requirements and Main Engine’s Power.
S-shaft delivers the required power output at consistent frequency and voltage, ensuring a stable and high-quality power supply for the ship.
This system can operate independently or in parallel with the ship’s auxiliary generator set, offering significant energy savings and environmental benefits, thereby enhancing overall economic efficiency.

S-Shaft PTO retrofit towards fuel-saving and short ROI
- Producing electric power utilizing M/E SFOC instead of D/Gen SFOC offers significant fuel-saving benefit
- Utilizing the redundant power of M/E will improve the M/E SFOC due to load increase
- Reduce EEXI
- Improve CII
- Reduce carbon emissions and respective penalties FuelEU, EU ETS, IMO GFI
- Reduce maintenance and operational costs of D/Gens
- Achieve ROI < 3 years

SETH can undertake turnkey projects undertaking the design, manufacturing, and delivery Shaft Generator onboard.
