Description

  • The Curlew cluster is located in Block 29/7 of the United Kingdom Continental Shelf (UKCS) in the central North Sea. It is situated 197 km SE of Aberdeen.
  • The Curlew development is a Floating Production, Storage and Offloading vessel (FPSO) Maersk Curlew FPSO, located over the Curlew reservoir.
  • The FPSO has equipment for oil and gas processing, storage and offloading, gas processing and export and treatment of produced water. Oil from the Curlew FPSO is exported onshore via shuttle tanker, while gas is exported from the Curlew FPSO to the SEGAL St Fergus Gas Processing Terminal via the Fulmar Gas Pipeline
  • There are 3 subsea tie-backs to the Curlew FPSO:
    • Curlew B field produced from a single well;
    • Curlew C field produces from a single well (re-uses the original Kyle dynamic riser) with gas lift and associated subsea structures;
    • Curlew D field produces via two production lines from four wells tied back to a production manifold together and associated subsea structures;
  • The Kyle Oil Field was tied to the FPSO back until 2005, but is currently physically disconnected and was connected instead to the Petrojarl Banff FPSO
