Preparation work is under way ahead of dismantling the 12,500 tonne Ninian Northern oil platform in the North Sea.
Contractor Allseas is currently carrying out preparation work using its Oceanic offshore construction vessel.
That includes installing underdeck lift points and removal of pipework and other obstacles.
It comes ahead of a ‘single lift’ operation to remove the topside by the Pioneering Spirit expected next year, which will deliver the platform to the Dales Voe facility in Shetland.
The 7,000 tonne steel jacket will be removed by 2023 at the latest.
