A/S Norske Shell has taken the decision to decommission the Gaupe subsea infrastructure associated with the Gaupe Field.
The Gaupe field comprises two production wells in the Norwegian sector, Gaupe North and Gaupe South. Fluids from the two drill centres were commingled at the Gaupe SSIV manifold, located close to the Armada Complex located in the Central North Sea 250 km East of Aberdeen in the UKCS. The Gaupe wells are tied back to the Armada Complex via two 8” / 12” pipe-in-pipe systems and a flexible riser installed within a platform conductor caisson. Controls for the field were provided by the Armada Facilities via two electro-hydraulic control and chemical supply umbilicals, one to each drill centre.
The Armada Complex is in a water depth of about 89 metres. Gas and condensate are sent towards the North Everest platform, with gas entering the Central Area Transmission System (CATS) at the CATS Riser Platform which is bridge-linked to the North Everest platform. The condensate enters the North Everest owned Everest Lomond System pipeline before joining the Forties Pipeline System at Forties Charlie. The Armada Facilities, CATS Riser and facilities beyond are outwith the scope of the decommissioning programme presented here.
The Gaupe wells were tied back through the Gaupe field pipelines above to the Armada Complex and came on stream in Q1 2012. Approval-in-principle from the OGA for cessation of production (CoP) of the Armada Hub and associated tiebacks was granted in August 2016.
In November 2017, the Armada Complex was divested to Chrysaor Holdings Limited with the intent of extending field life and CoP has been deferred.
The Gaupe wells and associated subsea infrastructure were not part of the divestment and remained within the Shell portfolio.
A/S Norske Shell submitted draft Decommissioning Programme (DP) covering the Gaupe Field’s infrastructure on the UK Continental Shelf, to the Department for Business, Energy and Industrial Strategy (BEIS) on 11 June 2020 in accordance with the provisions of the Petroleum Act 1998 (the Act), for consideration by the Secretary of State for BEIS. It is a requirement of the Act that interested parties be consulted on such decommissioning proposals.
The Gaupe Field infrastructure on the Norwegian Continental Shelf is covered by an existing approved Decommissioning Plan under Norwegian Regulations.
Public Consultation on the Gaupe Field DP opened on 11 June 2020, and closed on 10 July 2020. Following Public Consultation, the DP has now been approved by BEIS (OPRED).
The DP and supporting Comparative Assessment Report and Environmental Impact Assessment are available for download below: For any queries, please email SUKEP-Shell-Decommissioning-Correspondence@shell.com.
The Gaupe Field DP is also available on the BEIS website.
