Single screw
The shaft power submenu for single screw vessels (Figure 27) will show the actual power, the average
values over the last 1-4-24 hours and the Total Energy consumed at just one screen.
Twin screw
In case the PEM4 + SPU3 system is monitoring shaft power output for a twin screw propulsion installation
the information will be divided over four consecutive PEM4 screens.
The actual power is shown with different bars in the Shaft Power submenu, Figure 28.
The actual power and the average values over the last 1-4-24 hours are shown in the Power Averages
submenu, Figure 29.
The Total Energy consumed are shown in the Total Energy submenu, Figure 30.
The Accumulated Energy is shown in the Acc Energy submenu, Figure 31.
Auxiliary Engines
As an option the power level and fuel consumption of the generators driven by the Auxiliary Engines can
be monitored through the PEM4 + SPU3 system.
See “Power/Energy Aux” in figure Figure 28, Figure 29, Figure 30. For more details see section 7.6.6.
The values can set back to zero by touching the Reset button.
