Preparation works for complex second lift

TasPorts’ insurer, Shipowners, and salvor United Salvage, with support from TasPorts, have continued the preparatory work for the salvage of the Campbell Cove wreck from the Mersey River in Devonport.

TasPorts chief operating officer Stephen Casey said these works would continue for much of today (9 August) for an initial lift attempt to be undertaken as soon as practical.

“Much of yesterday was focussed on finalising the safe landing of the York Cove into the cradles on board the AAL Melbourne to the satisfaction of the vessel’s Master for a sea voyage,” he said.

“The wreck, and the Campbell Cove wreck when it is ultimately salvaged, will be welded to the cradles on the deck for transport to Brisbane where there is a salvage yard dedicated to scrapping maritime assets.

“Further, due to the damage to the York Cove and suspected warping of the hull from the allision, there have been complexities associated with its positioning onto the specially constructed cradle that is sitting on the AAL Melbourne.

“The delays experienced in landing the York Cove have in turn prevented transferring the rigs to set up the Campbell Cove for lifting.”

Mr Casey said while the team overseeing the project had taken a lot of learnings out of the first lift, the Campbell Cove lift presented its own unique set of challenges.

“The wreck was wedged between the wharf and the wreck of the York Cove which meant divers were not able to inspect the extent of the damage, though we knew it was significant,” he said.

“It is also sitting in an unbalanced position.

“A pre-lift will likely be required to move the wreck into an upright position that will make the full lifting operation much safer.

“The two cranes lifting the Campbell Cove will be operating from a floating ship which adds to the complexity of the operation.

“It will be a slow and deliberate piece of work.

“Allowing the wreck to dewater or drain what is largely sea water, mud and silt is also important. This will be happening in the containment area in case there is any oil or diesel in that waste.”
