MMA OFFSHORE’s Port Taranaki-based anchor-handling tug supply ship (AHTS) MMA Vision is en route to Westport on NZ’s South Island West Coast to begin recovery attempts on WMS Group’s self-propelled bulk barge Manahau, which stranded at Carters Beach on Saturday night.
MMA Vision, which normally works in Taranaki Basin oil & gas fields, has become NZ’s de facto salvage tug having attended a number of casualties in recent times. It departed New Plymouth at 1430 hrs this afternoon, local time, and is expected at the salvage site around 2300 tomorrow.
According to local sources Manahau probably lost its port Azipod in the initial grounding in bad weather, and the starboard unit has since dropped off and is thought to be underneath the vessel, which was in ballast at the time of the incident. Two skegs under the stern were removed last night.
In the latest update Maritime New Zealand has advised that formal restricted access areas are now in place around the grounded barge, to protect the public from harm while the operation continues to secure and salvage Manahau. The restrictions have been implemented under the Maritime Transport Act and are subject to change.
National On-Scene Commander Mick Courtnell said on-shore heavy machinery is operating, while on the water it was important to keep away from the vessel and the tethers it has keeping it in place: “Our priority is the safety of people, the environment and property.”
While there have been strong swells over the last 24 hours, there is no immediate risk of its fuel leaking, MNZ said.
In preparation for the salvage, which is managed by the operator (WMS subsidiary West Coast Bulk Logistics), response teams have been working to ensure the vessel remains secure on the beach. It is held by its anchors, which have been buried in sand, and seven five tonne blocks of concrete to prevent significant movement.
MNZ’s oil response experts are working with local authorities on environmental protection plans. Personnel and specialist equipment has been mobilised as part of precautionary plans to protect the local environment in the event of any spill.
The 11-strong Indonesian crew remain on board Manahau. The operator has reported that they are safe and well and have been offered welfare services.
