On 18 June 2012 a media statement was released detailing the initial circumstances surrounding the defect which occurred on one of the propulsion transformers in HMAS Choules on 14 June 2012. This is an update to that release.
At the time of the incident all other transformers were checked by the transformer manufacturer (Siemens) and found to be within specification.
Following the removal of the two starboard side propulsion transformers, further investigation has been possible and this has indicated signs of premature ageing.
Deeper level inspections of all remaining transformers in the ship have now revealed similar problems but at varying levels.
The transformer manufacturer is yet to confirm that this contributed to the failure of the starboard propulsion transformer.
Work is now underway in conjunction with the transformer manufacturer, the on-site support agencies and Defence Science and Technology Organisation to determine when the remaining transformers need to be replaced.
The Defence Materiel Organisation is also contacting the UK Ministry of Defence to coordinate further investigations.
Should HMAS Choules be further delayed in her return to service, HMAS Tobruk and Australian Defence Vessel Ocean Shield will provide any humanitarian assistance or disaster relief response if required by the Government.
