Superyacht controls & instrumentation systems troubleshooting

2. Generator load sharing problem

• Symptoms: Port / starboard auxiliary generators have asymmetrical load sharing and overloads causing 'dead ship'.
• Cure: measurements and analysis of powers from both generators; diagnose and recalibrate generators instrumentation using load banks.

3. Generator stability problems - cannot synch reliably - a common problem!
Symptom: The usual two generator set-up, the off-line generators is 'hunting' and is not stable enough to synchronize with the bus.
Cure: Examine stability range of actuator/deisel motor and change hardware to suit symptom details. Restabilise using oscilloscope to monitor overshoot and damping.

4. Telemetry system - ships monitoring system to send alarm SMS to mobile phone
Symptom: The superyacht has insurance cover to be left without on board watch keeper for periods of time - what happens if the monitoring system detects an alarm?
Cure: Add a telemetry system to alert Captain and First Mate by SMS for each alarm condition. The alarm can be cancelled remotely.
