Description

  • The **Hannay Field** is a subsea development that was tied back to the Buchan Alpha facility
• The field was closed down in 2017 but is to be redeveloped
  • Re-development of Buchan is based on a new production hub located at the Buchan field utilising a floating production, storage and offloading (“FPSO”) vessel. The vessel is to be the Western Isles FPSO
  • Subject to project sanction and regulatory approval, the target for first production is late 2026.
  • Peak production rates are expected to be around 35,000 barrels per day.
