GDF Suez, Centrica and Bayerngas sanction Cygnus development
GDF Suez and its partners Centrica and Bayerngas awarded the detailed design contract to AMEC for the development of the Cygnus natural gas field in the UK continental shelf in the southern North Sea.
Then several appraisal wells were conducted until 2010 leading GDF Suez to revise upward the first estimated reserves of this gas field to proven and probable (2P) reserves amounting to approximately 18 billion cubic meters.
Cygnus reservoir is located 150 km off the coast of England, in shallow water of 23 meters deep, then by 3721 meters deep and contains high quality raw natural gas.
The partners share working interests in Cygnus as following:
– GDF Suez 38.75% , is the operator
– Centrica 48.75%
– Bayerngas 12.5%
GDF Suez estimates the natural gas Cygnus project capital expenditure to $2.2 billion (1.7 billion Euros) and should provide with 4,000 direct and indirect jobs during construction phase.
AMEC completed FEED for GDF Suez Cygnus
AMEC completed the FEED work by mid 2012 allowing GDF Suez and its partners to sanction the next steps of Cygnus development.
From the FEED work the development concept is based on:
– Two drilling centers, one hub and one satellite located at 5.9 kilometers distance
– Four platforms, three platforms should be bridge-linked at the hub including the living quarter and utilities and the fourth one normally unmanned at the second center
– A first phase of 10 production wells
– An export pipeline through the Esmond Transportation System (ETS) to the Bacton gas terminal in North Norfolk.
GDF Suez and its partners, Centrica and Bayerngas, expects AMEC to complete the detailed design work in 2014 for first natural gas deliveries from Cygnus in 2015.
GDF Suez awarded first contracts to Heerema, BiFab, Ensco, Seaway Heavy Lifting and Saipem
While AMEC was awarded the conversion of its FEED contract into a detailed design contract, GDF Suez awarded also directly other large packages:
– Heerema Fabrication Group (Heerema) will produce the topsides
– Brunstisland Fabrications (BiFab) won the four jackets and associated piles
– Ensco will perform the main drilling operations
– Seaway Heavy Lifting is in charge of the transportation and installation of the platforms in addition to the subsea structures
– Saipem has been awarded the export pipeline
