needs to improve throughout the marine industry as the risks to equipment caused by harmonic distortion are likely to increase significantly as variable speed AC electric motors become more widely used in ships. • Regular monitoring of electrical networks should be undertaken and monitoring equipment should be capable of detecting transient voltage spikes, resonances, and excessive
harmonic distortion levels. • Procedures need to be established to manage distortion levels in the event that power conversion equipment or harmonic mitigating equipment fails. • Machinery alarms should be regularly reviewed and prioritised so that the risk of the watchkeeper being overloaded with too many alarms and not noticing those from critical
systems can be minimised. • Queen Mary 2 experienced two brief power interruptions during routine maintenance, whilst at sea en route to Fremantle in February. All main lighting, essential services, safety equipment and engine/bridge control equipment retained power throughout, via the back- up power supply systems on board. Full power was restored with no impact on passengers.

The interiors may have been significantly restyled for seven- day sailings, but the vessel remains technically the same as sistership Disney Dream, which set sail in January 2011. It was reported that the
ship suffered vandalism in early December while under construction, but Meyer Werft stated that all the damage had been repaired with no effect on completion or delivery. PST
