Interislander returns - costs of $25m

The Interislander ferry Aratere will arrive back in Wellington on Wednesday after lengthy repairs -- with the total cost to taxpayers including lost revenue and a stand-in ferry totalling more than $25 million.

The ferry has been in Singapore since March, where it has undergone testing and repairs, after losing a starboard propeller in November.

At a media briefing this morning KiwiRail said the overall financial impact including lost revenue, charter of the replacement ferry Stena Alegra and cost of repairs is estimated to be between approximately $25 million and $30 million.

KiwiRail continue to maintain that there was no warning of the loss of the propeller, and said none of the ship's control system monitors were abnormal.

While in Singapore, a number of national and international experts looked at all potential factors that could have led to the tail shaft failure.

KiwiRail said from those expert opinions, and findings while in Singapore, they have concluded there were a number of factors that led to the loss of the starboard propeller.

As a result they were now reviewing their insurance, commercial and legal position, and because of this they were unable to say more as to what caused the malfunction without "prejudicing their position."

Details of work to be carried out over the next fortnight will include more sea trials and underwater inspections.

A leak down test to check for oil leakage and a crash stop to measure the stopping distance of the ship will also take place.

NZ First leader Winston Peters said KiwiRail should announce who will be fired for the Aratere debacle after the financial impact was announced.

"Incompetent management, on high salaries, should be paying for this with their jobs."

KiwiRail chief executive Peter Reidy acknowledged that people had lost trust in them, and said the company would now work to regain that trust.

"We're being transparent about what happens, and being transparent about what we're doing in the next two weeks to get this back into service."

The Aratere carries out 45 per cent of KiwiRail's capacity, alongside Interislander ferries Arahura and Kaitaki.

The Stena Alegra was replacing it's services, and had its last Cook Strait crossing last Saturday. The Aratere is tentatively scheduled to resume service from July 14.

Will we hear the truth?

Well,well,well! The final report due in November will be interesting, although knowing Kiwirail I have real doubts about whether we will ever be told the basic reason for the failure. Kiwirail states: "KiwiRail continue to maintain that there was no warning of the loss of the propeller, and said none of the ship's control system monitors were abnormal." but then go on to say," KiwiRail said from those expert opinions, and findings while in Singapore, they have concluded there were a number of factors that led to the loss of the starboard propeller."

These two statements are very strange, to say the least. It is a fact that the propellor shaft broke, which is extremely rare. Prior to breakage there would have been a slow build-up in vibration which should have triggered an alarm in the monitoring system. Did this happen? Was the propellor mounting area fully crack-tested during the vessel's last survey?  And were the rudder stocks that had to be replaced  fully inspected during the last survey? If not - why not?

Judging by Kiwirails past responses to OIA requests about Hillside locomotive quotations I do not believe we will be told the truth. At a loss of $45m there should have been an independent inquiry. 

Penny wise pound foolish

$25 million. Let's see - how many trips across the strait and back before we se a profit again?
