Field facts

The biggest natural gas discovery in the southern North Sea in over 30 years is now the largest single producing gas field in the UK, typically exporting over 250 million standard cubic feet of gas daily. Cygnus contributes six per cent of UK gas production, supplying energy to the equivalent of 1.5 million UK homes. It has a field life of over 20 years.

Two drilling centres target ten wells. Cygnus Alpha is made up of three bridge-linked platforms: a wellhead drilling centre, a processing/utilities unit and living quarters/central control room. Cygnus Bravo, an unmanned satellite platform, is approximately seven kilometres 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. Neptune Energy has a 25% minority interest in ETS.
