ONEgas, a joint venture between Shell and Nederlandse Aardolie Maatschappij (NAM), has awarded a three-year contract in the UK to Petrofac.

The award builds on a previous framework agreement with the British oilfield services firm and includes two one-year extension options.

Under the contract, Petrofac’s Engineering and Production Services business will be responsible for providing engineering, procurement, and construction (EPC) services to support ONEgas’s Southern North Sea assets.

These assets include the Clipper South complex, Leman Alpha, the Bacton terminal, and ONEgas barge campaigns.

The Clipper complex is located in the Southern part of the UK North Sea in the Sole Pit field. It is situated 73km from Bacton and 66km from the nearest point of the Norfolk coast.

The Leman Alpha installation is in the southern part of the UK sector of the North Sea, 69km (43 miles) north-east of Lowestoft, 50km (31 miles) from Bacton and 48km (29 miles) from the nearest point off the Norfolk Coast.

The Leman Alpha installation is equipped to produce and process natural gas from its own wells.

In addition to importing and processes gas from the other Leman field platforms, Bravo, Charlie, Delta, Echo, Foxtrot and Golf, the installation imports natural gas and liquids from Corvette, Brigantine (BG and BR), Caravel and Shamrock.

The Bacton gas terminal complex receives gas from offshore lines, including the Southern North Sean fields of Leman West area, the Sean area and the Sole Pit area.

It also gets production from Central North Sean through the Shearwater Elgin Area Line (SEAL).

Petrofac engineering and production services chief operating officer Nick Shorten said: “Over the last 18 months Petrofac’s UK brownfield projects business has achieved notable growth.

“Our best-in-class engineering teams, scalable delivery model and project control systems are now being deployed in support of more than 30 assets in the UK.”
