5.4.2 Recommended manoeuvring characteristics
The vessel speed is adjusted by the engine telegraph. Manoeuvring, e.g. for
leaving a port, is available from full astern to full ahead. For regular full sea op-
eration, the engine power can be further increased up to 100 % CMCR power.
To protect the engine, any increase or decrease in power is limited by a rate of
change, considering the warm-up respectively cool-down times. Therefore, de-
pending on the magnitude of any change in power, it takes time to reach the re-
quired engine output; see the following graphs and tables.
