Variable speed shaft generator (PTO/PTI)

Are you looking for support or purchase information?

Using the energy efficient main engine to generate electrical power (PTO), the system can boost the main propulsion shaft (PTI), and also provide Power take home (PTH) for an extra layer of redundancy. In addition, the system offers the opportunity to connect energy storage, shore to ship power and other new energy sources and functionalities to the power and propulsion plant.

Comply with regulations

Add new functionalities and energy sources to the power plant, such as energy storage and shore connection, for a future proof vessel.

Lower CAPEX

Optimise the power plant with smaller or fewer auxiliary engines, and the option of lower maximum engine design power without lowering maximum vessel speed.

Faster payback time

The highly efficient system enables faster payback time by reducing fuel consumption.
