Defence will spend $10M on repairs to have all of its' propulsion transformers replaced.
The ship should be back in service by April.

Another report in The Australian says:
A Royal Navy report from early last year indicated engineers had noted that when it was sailed at full speed its propulsion motors and transformers tended to overheat.
"The running of equipment at near maximum temperatures on a regular basis will likely cause early failure of the motors and transformers," the report said.
Was this ignored at the time of purchase?
Hopefully the ship will be fully operational once the transformers are replaced.
This may have something to do with the outcome. To Warren King. “Senator JOHNSTON: All right. Did we see Captain Wardell's letter to Mr Smith of Ships Projects Acquisition and Resourcing in the Disposals Services Authority, dated 6 February 2011, wherein he outlines some 21 issues with respect to RFA Largs Bay, as it was? Unable to maintain full speed due to overheating of propulsion motors and transformers. DEFREP ME01-11 refers. The lack of natural ventilation in the transformer rooms is a constant cause for concern. The fan coil units … fitted to cool the rooms cannot cope when the ship is operating at higher speeds, especially when in higher sea temperature conditions. Any loss of supplies to the FCU's will result in the transformers overheating. A natural vent would funnel the hot air out of the rooms and the FCU's could then become a secondary means of cooling. The running of equipment at near maximum temperatures on a regular basis will likely cause the early failure of the motors and transformers.”
Read the pages of nonsense presented by Warren King. Senator Johnston had to bring the letter to his attention, and he admitted they did have it .Never mentioned it. “Mr King: I believe so. I would need to see the letter, but I believe we have it.” Believe we have it? Incredible. Talk about incompetence.

There was a full update to the Senate Estimates Committee on this issue in October. It can be found between pages 37 and 39 here:

What do they say is the root cause of the problem with the transformers and the causality chain that led to the problem, in the first place?
This may have something to do with the outcome.
