Rena has suffered substantial structural failure, with a crack appearing in the number three cargo hold on the starboard side. This has been caused by the movement of the vessel as the stern, which has remained afloat, shifting with the waves, while the front part of the ship remains stuck on the reef.
There is a concern that the stern of the vessel may break away. The salvors have three tugs mobilised either to hold the stern on the reef while further effort is made to remove the oil, or to tow the stern to shallow water where they will remove the oil. Naval architects are working on possible scenarios. Iwi are also involved in advising on any cultural issues regarding moving or sinking the ship.
A number of containers have now come off the vessel. Those remaining continue to move, making it extremely dangerous for salvage crews to work on board. Six vessels have been mobilised to intercept the drifting debris in the water.
There will be substantial oil on the beaches, in the water and on the foreshore. This is expected to result in around 10,000 tonnes of sandy waste. There are 20 teams on the beaches, comprising about 250 people, cleaning up the oil. Four vessels are in the harbour to deal with any oil that may enter the area
