Neptune Energy let a 2-year contract extension to Petrofac Ltd. for engineering services for the Neptune-operated Cygnus Alpha and Bravo platforms in the UK Southern North Sea.
Petrofac will provide a range of brownfield engineering, procurement, construction, and commissioning services for Cygnus field. It follows the award of a separate, 3-year contract extension to the company earlier this year for operations and maintenance support in the UK.
The contract extension will take effect from Jan. 1, 2022.
Cygnus field is 150 km off the coast of Lincolnshire and produces more than 250 MMcfd of natural gas with 2P reserves of about 636 bcf. Two drilling centers target 10 wells. Cygnus Alpha consists of three bridge-linked platforms: a wellhead drilling center, a processing-utilities unit, and a living quarters-central control room. Cygnus Bravo, an unmanned satellite platform, lies 7 km northwest of Cygnus Alpha. Gas is exported via a 55 km pipeline. Cygnus connects via the Esmond Transmission System (ETS) pipeline to the gas-treatment terminal at Bacton, Norfolk (OGJ Online, July 21, 2021).
Neptune is operator of Cygnus field with 38.75% interest. Spirit Energy holds 61.25%.
