17.6 Turning gear
The engine is equipped with an electrically driven turning gear, which is capable of turning the
propeller shaft line in most installations. The need for a separate turning gear with higher torque
capacity should be considered for example in the cases listed below:
● Installations with a stern tube with a high friction torque
● Installations with a heavy ice-classed shaft line
● Installations with several engines connected to the same shaft line
● If the shaft line and a heavy generator are to be turned at the same time.
