United Kingdom – Lerwick Harbour is to be the location of a decommissioning project following the award of a major North Sea contract to Veolia/Peterson, to dismantle and recycle a northern North Sea platform jacket.
It comes after they were awarded the contract to decommission the 14,500-tonne topside for the same platform, which was recently completed on time at the port’s Dales Voe Base, with Veolia/Peterson exceeding their target of more than 98 percent materials recycled.
Allseas, a leading international contractor, has awarded the latest project. The 83-meter-high steel jacket, which weighs around 8,500 tons, will be delivered in April by Allseas’ Pioneering Spirit, the world’s largest and most sophisticated construction vessel.
The site is currently preparing for the arrival of the jacket. It will be removed in a single lift, just like the topside, and transported ashore at the base via barge. A purpose-built heavy-duty decommissioning pad will be used once more. The jacket’s decommissioning is expected to take eight months to complete.
The drilling and production platform with eight legs was installed in 1978 and put into service in 1980. In 2017, production ceased.
