New Zealand Prosecutes RoRo Operator for Blackout Due to Maintenance Issue

New Zealand regulators have taken the unusual step of filing charges against the operator of a large inter-island ferry after the vessel suffered a power failure a year ago. The charges now in a New Zealand court came after an extensive investigation by the regulator Maritime New Zealand as well as a critical report from the country’s Transport Accident Investigation Commission (TAIC) which called on Maritime New Zealand to address critical safety issues.

The incident began late on the afternoon of January 28, 2023, with 800 passengers and 80 crew aboard the ferry as it was approaching Wellington, New Zealand. KiwiRail promotes that it is “the original Cook Strait ferry,” with multiple sailings each day between the North Island and South Island (Wellington and Picton) carrying passengers, cars, trucks, and rail cars. The trip normally takes about 3.5 hours, but during the crossing, the vessel can be exposed to strong weather conditions. The 2023 trip was no exception with winds of 30 to 40 knots.

TAIC in its preliminary report found that a rubber expansion joint had ruptured and most of the cooling water drained out before the crew could stop the leak. A review of the ship’s propulsion systems showed there were 12 rubber expansion joints. The one that failed they found had been manufactured in 2005 and sat on a shelf till it was installed in 2018. Two others in use aboard the ship were found to be 13 years old and had also been in use since 2018. 

TAIC said the company had failed to track the parts and follow recommendations. They said closer attention was required because it is common for manufactured rubber components to become more susceptible to cracking, delamination, or to become softer or “gummy” as they age.

The company faces a fine of up to approximately US$900,000 if found guilty. News of the charges however has also restarted a debate over the need to replace the ferries. Union leaders and politicians are saying the ferry is too old and like an old car, in time they just do not run anymore
