MACHINERY
Each marine diesel engine drives a fixed pitch propeller via a shaft with flexible coupling and reverse / reduction gearbox with clutch. For the shaft arrangement both torsional and lateral (bending) vibration analyses are or have been performed to avoid resonance in the working speed range. All machinery is marine type and the installation is laid out for easy watch keeping, servicing and maintenance.Starting and stopping of the main engines is in the engine room and also from the bridge. For safety reasons a local switch(es) is fitted in the engine room, which will prevent the engines being started by remote control.
