Metal debris from a 17,000-tonne rig that ran aground in the Western Isles has been found on a nearby beach.

Around 40 pieces of steel weighing up to 90kgs have been discovered around Dalmore Beach on Lewis, where the Transocean Winner became stranded on rocks.

Debris including scaffolding fell from the vessel after it crashed near Carloway during a storm on August 8.

It was towed free last week and taken to Broad Bay on the far side of the island, where it is being inspected for damage.

Dog walkers and surfers who frequent Dalmore Beach have been warned to look out for pieces of the rig which may appear over the next few months.

The Maritime and Coastguard Agency has said an exclusion zone will remain in place until a counter-pollution team removes the debris.

Colin Mulvana, the deputy secretary of state’s representative for maritime salvage and intervention said: “Divers are working very hard to make sure that they are picking up all the bits found on site.

“But there may well be previously undetected debris that may appear following bad weather. A future programme of surveys will be discussed and put in place by Transocean in an effort to ensure the area is clear of debris and safe for members of the public.

“Our advice remains the same as it has from the start – please stay off the beach while the diving operation continues and while the Temporary Exclusion Zone is still in place.

“We know that surfers and walkers, including those with dogs, use Dalmore Bay and will continue to use it after the diving operation is over and the exclusion zone has been lifted.”

Transocean is considering breaking-up the salvaged rig in the UK, with yards in Belfast, Nigg and Kishorn flagged up for the work.
