Arahura sea trials successful

07 November 2014 1:01PM

Interislander engineers spent the night working and testing on board Arahura.  Full test have been carried out of the bridge and engine room controls, as well as the safety, alarm and override systems.  The engineers are confident the fault has been identified and successfully repaired, and successful sea trials were carried out.

The fault has been traced back to a failed electronic card which controls the pitch of the vessel’s propellers.  The card has lasted thirty years and is not a component which is prone to failure.  It has been replaced.  Interislander is in discussion with the manufacturers of the card in order to better understand the failure and minimise the chances of a similar incident in future.    

Both Maritime New Zealand and the ship’s classification society are satisfied the vessel has been repaired to the appropriate standard and have given her approval to sail.  A decision regarding Arahura’s 1830 departure from Wellington will be made at 1530.  If this sailing proceeds, it will be as a cargo vessel only and passengers booked on this service have been rebooked onto the Kaitaki sailing at 2000. 

The Master on yesterday’s 0630 departure from Picton has confirmed under two minutes elapsed from the first indication of yesterday’s fault to deployment of the vessel’s anchors and the ship being made secure.
