An investigation is underway into a freight ship that lost its rudder as it departed Tauranga Harbour.

Bulk carrier MV Achilles Bulker, was departing Tauranga harbour about 3.30pm on July 24 when it lost its rudder and subsequently suffered a steering failure in the harbour’s main channel.

Maritime NZ says a detention notice is in place against a log carrying vessel, which is currently anchored off Tauranga.

The Panamanian flagged Achilles Bulker was departing Tauranga bound for China when it encountered the steering problems.

In a statement released on Monday, Maritime NZ says the vessel remains anchored off Mount Maunganui, and the rudder was recovered by divers last week and brought to shore.

“The detention notice means the vessel is prohibited from leaving Tauranga until the certain conditions have been satisfied.

“Due to the rudder failure, the Achilles Bulker will need to be towed to a dry dock for repairs.

“The owners of the vessel are responsible for managing the towage process.

“Maritime NZ is working closely with the Bay of Plenty Regional Council and the Port of Tauranga on the arrangements to bring the vessel back into Tauranga to remove the cargo of logs before it can be towed.”
