Shafts and associated components used for transmission of power. The main propulsion shafting system consists of shaft sections connected by means of bolted flange couplings and supported by bearings that maintain the shafting in proper alignment.
- Intermediate shafting – Lengths of shafting between a power source and a propeller shaft.
- Line shafting – The shafting located inside the ship.
- Wet shafting – The shafting located outside the ship.
