Dales Voe at Lerwick

Following the award of another major North Sea contract to Veolia and Peterson, Lerwick Harbour will be the location for the dismantling and recycling of a northern North Sea platform jacket.

This follows the winning of the contract to decommission the 14,500 tonne topside for the same platform, which will be the biggest to date at the port’s Dales Voe Base. This was recently completed on time with Veolia and Peterson achieving their target of more than 98% of materials recycled.

The latest project has been awarded by Allseas and is for the 83-metre steel jacket which weighs in at around 8,500 tonnes. This will also be delivered by Allseas Pioneering Spirit.

Preparations are now underway for the reception of the jacket. Similar to the topside, it will be removed in a single lift before being transferred ashore at the base via a barge. A heavy-duty purpose-built decommissioning pad will be used.

John Abraham, COO of Veolia UK & Ireland – Industrial, Water & Energy, commented, “Industry leading recycling involves innovation and scrupulous planning. With our major complex decommissioning projects, we have already shown that it is possible to achieve a 98% recycling rate for obsolete oil and gas structures, a key achievement as we look to preserve resources and drive our ecological transformation. Decommissioning is also very important from a carbon perspective as recycling a tonne of steel saves 1.5 tonnes of iron ore and reduces CO2 emissions by 80%, compared to metal production from raw materials."

James Johnson, Decommissioning Manager at Peterson, remarked, “We believe this award demonstrates the strong track record of Peterson and Veolia in handling all types of offshore decommissioning projects, as well as the excellent capability of the Dales Voe Base. It is also recognition of the excellent work undertaken in the decommissioning of the Ninian Northern topside, where an industry first approach to decommissioning an offshore asset proved very successful. We are very pleased that the award will also help secure a number of Peterson roles on Shetland on an ongoing basis.”

The jacket is expected to arrive in April 2022 with decommissioning taking around eight months to complete from this point.
