Devenick-East Brae offshore development tieback onstream in North Sea

Offshore staff

LONDON -- BP has delivered first gas from the Devenick field in the UK central North Sea. Production from the field should peak next year at 100 MMcf/d. When Devenick is fully onstream it should add an extra 3% to UK gas production

The project is a subsea tieback 34 km (21 mi) to Marathon Oil’s East Brae platform to the south. Total investment by BP and partners RWE Dea UK has been around $1.047 billion. BP estimates the in-place gas reserves at 430 bcf, and production should continue through 2025.

The field was discovered in 1983 and a further three appraisal wells were drilled between 1986 and 2001. Recent advances in subsea technology finally allowed the partners to move ahead with an economic development.

Insulated flowlines connected to Devenick’s subsea manifold feed the gas to East Brae via a 16-in. (40.6-cm) insulated 34-km pipeline.

McNulty Offshore Construction in South Shields, northeast England, fabricated the new reception module for the platform, which was designed by Aker Solutions. Technip fabricated the pipelines and spools at its base in Evanton, northern Scotland. Isleburn in Scotland manufactured the subsea manifold and other subsea equipment, with JP Kenny managing subsea engineering, and Technip the subsea installations. Petrofac performed brownfield design and construction work.
