Maritime NZ has advised that the container ship Rena, which has been the subject of a major salvage operation off the Tauranga coast, has broken up in the most severe storm to hit the area since her grounding three months ago on the Astrolabe Reef.

Severe weather overnight has separated the MV Rena into two pieces, which are now about 20-30m apart on the Astrolabe Reef, Maritime New Zealand says.

Both sections of the vessel still remain on the reef, with the forward section remaining firmly wedged, while the aft section has separated and moved clockwise (or to starboard) about 13 degrees, after the ship was hit by seas of over 7m overnight, further worsening the damage it sustained following its grounding on the reef just over three months ago. The current bad weather is forecast to slowly ease over the next 3 – 4 days.

MNZ Salvage Unit Manager David Billington said the fresh damage to the ship had resulted in the loss of a large number of containers and debris. “While the two sections of the Rena currently remain on the reef, there’s no question the ship is badly damaged with the severe movement breaking off many of the hatch covers and releasing containers from the holds. Salvors are now working to assess the state of the vessel so that naval architects can undertake further calculations get to gain a clearer picture of its ongoing stability.”

Mr Billington said the vessel Go Canopus was currently connected to the aft section of the Rena and was continuing to monitor its status.

At least 23 containers had been confirmed as being lost from the ship, which was floating or partly submerged, with another 7 (unconfirmed) thought to be in the water. However, Mr Billington said more were likely to be lost. There was also a large debris trail, including wood, around the vessel.

Container recovery company Bramear Howells had tugs en route to tag containers with buoys as it was currently too rough to tow or safely recover them, while vessels with trawl nets would also be sent out to collect debris once weather conditions improved.

Navigational warnings had also been issued to shipping, with the port company communicating with individual ships via port radio and warnings issued to recreational vessels via Coastguard radio. Shipping lanes were also being monitored for containers and debris. The Bay of Plenty Regional Council Harbour Master is considering extending the 3nm exclusion zone due to the large debris field from Rena.

National On Scene Commander Alex van Wijngaarden said the National Response Team had been mobilised, which included trained oil spill response and wildlife experts, who were preparing for the likelihood of more oil coming ashore.
