Brae Decommissioning PLANNING

Brae Decommissioning Header

Marathon Oil has commenced planning for the decommissioning of the Brae area facilities in the UK sector of the Central North Sea.

The Brae area lies approximately 170 miles (274 km) north-east of Aberdeen within three principal UK Blocks: 16/7a, 16/3a and 16/3b. Marathon Oil U.K. LLC is the operator and equity partners are TAQA Bratani Limited, TAQA Bratani LNS Limited, Centrica Resources Limited, and JX Nippon Exploration and Production (U.K.) Limited.

The Brae area includes three production platforms: Brae Alpha, Brae Bravo and East Brae. Three equity subsea installations and connecting pipelines, flowlines, control umbilicals and utility/power cables, and export pipelines complete the infrastructure.

Brae Field LayoutThe three platforms are supported on steel jackets with modular topsides. Brae Bravo has a secondary jacket supporting the flare, which is connected to the main platform by a steel bridge. The platforms stand in approximately 110m of water and are interlinked by the field power generation system.

Brae Alpha commenced production in 1983, Brae Bravo in 1988 and East Brae in 1993. The Central and West Brae/Sedgwick subsea tiebacks to Brae Alpha commenced production in 1989 and 1997, respectively. The Braemar subsea tieback to East Brae commenced production in 2003.

Liquids from the Brae area are exported via the Forties pipeline to Cruden Bay, and then on to Kinneil near Grangemouth.

Gas is transported via the Scottish Area Gas Evacuation (SAGE) pipeline to St. Fergus.

The Brae platforms, pipelines and infrastructure are also used by third parties – please see overview diagram.
