Recovery activities around the grounded vessel, Black Cat, at Nīkau Palm Valley Bay in Akaroa will get underway today following the consultation of a recovery plan, Canterbury Regional Council (Environment Canterbury) has advised.
The Council continues to work alongside salvage teams and insurers to minimise impacts to the environment, with aligned partner agency and stakeholder interests.
The recovery operation is expected to take 15 days, subject to weather and sea conditions.
The work is being undertaken in two phases:
- Phase one will focus on the removal of the vessel’s superstructure and any debris from the beach. This work will involve cutting up the superstructure in place and removing material using a barge and crane. This phase is expected to take around five days;
- Phase two will involve the removal of the submerged hull sections and debris from the seabed. This will require diver teams to carry out a full investigative survey of debris fields before recovery begins, along with the use of specially fabricated floats to safely lift and remove the hull sections. This phase is also expected to take approximately five days, but timing will depend on the weather and sea conditions.
The boat ramp in Children’s Bay, Akaroa Harbour, will be closed periodically throughout the operation to ensure the safety of contractors and the public. All efforts will be made to keep these closure periods as brief as possible, but safety on the site is paramount, the Council says.
Regional On-Scene Commander, Emma Parr said safety will remain the top priority throughout the operation.
“Recovery activities will only be undertaken when conditions are safe for crews, and any potential environmental impacts have been minimised. This includes pre and post-wildlife surveys and hydrocarbon testing of water, sediment and shellfish,” she said.
“Weather and sea conditions will play a key role in determining when work can proceed on any given day.”
The public is reminded that the 200 metre exclusion zone remains in place around the vessel and recovery site.
“The exclusion area is critical to keeping people safe while complex recovery work is underway. We ask the public to please respect all signage, on-water restrictions and advice from response crews.”
On-water monitoring of the site and surrounding area will continue throughout the recovery operation, with assistance from partner agencies and stakeholders, including the NZ Defence Force’s Rigid Hull Inflatable Boat, she explained.
“Removing the vessel and debris from this sensitive area is a priority, and all parties involved remain committed to completing the recovery as safely and efficiently as possible.”
Council Chair, Deon Swiggs said he was glad to see a plan in place.
“The response team has done an exceptional job managing a complex and fast-moving situation alongside our iwi partners and DOC, and in collaboration and with advice from Maritime New Zealand, the Transport Accident Investigate Commission (TAIC) and Wildbase,” he said.
“Their strong focus on safety for crews, the public and the environment has guided every decision, and their expertise and teamwork has been evident throughout.”
