In October 2011 the cargo ship Rena ran aground on the Astrolabe reef 15 miles off the coast of Port of Tauranga, New Zealand. This ships grounding created one of the worst environmental maritime disasters in New Zealand history.
1300 tonnes of heavy fuel oil and 1700 containers have to be removed. To remove the containers ‘PB Seatow’ set up two large crawler cranes on a large barge that could be moved in close around the shallow waters of the wreck. These cranes would then lift the containers off the wreck and on to a waiting ship to be transported back to Tauranga. This operation would take somewhere between 6 months to 2 years and during this time the two cranes would be exposed to the harse salt water conditions and corrosion.
