Oilfield services firm Petrofac announced Friday that it has been awarded a three-year contract, worth approximately $157 million (GBP 100 million) per year, to supply engineering and construction services to Apache North Sea.

Petroface will supply onshore engineering as well as onshore and offshore construction to all of Apache North Sea’s assets, including the Beryl Alpha and Bravo platforms in the northern North Sea and the Scottish Area Gas Evacuation (SAGE) gas-processing plant at St. Fergus, Aberdeenshire, Scotland.

The contract represents an extension to, and continuation of, the firm’s current service contract to service Apache’s offshore platforms in the Forties field, 110 miles east of Aberdeen.

“We have worked closely with Apache to deliver a number of highly successful projects on the Forties field since we began work in 2009. As Petrofac develops its offshore capability we are delighted that Apache has extended our responsibilities to include engineering and construction work on the Beryl field and at the SAGE gas plant,” said Bill Dunnett, Petrofac’s managing director, in a statement.

The deal is the second major piece of contract news to come out of Petrofac within a month. In June Petrofac, along with Schlumberger, was selected as a preferred bidder by Petróleos Mexicanos for a 30-year contract, which Petrofac expects to sign in August, to deliver production services to the Pánuco project, onshore Mexico.
