Leman F & G
Shell U.K. Ltd has taken the decision to decommission the Leman F & G Platforms, and associated subsea infrastructure, having received Regulator approval 11 January 2024.
The Leman Gas Field was discovered in December 1965, with production from Leman commencing in 1968. The Leman F & G Platforms are two Normally Unattended Installations (NUIs) which, since 1987, have supported production from the Leman Field. Situated 48km and 51km north-east of Bacton in the Southern North Sea area of the U.K. Continental Shelf respectively, production from Leman F & G is exported to the Leman A Complex via subsea pipelines before it is exported to Bacton.
Both NUIs are reaching their end-of-life and are expected to cease production in the mid-2020s, and are therefore planned to be decommissioned, along with the associated pipelines and cables running between them and towards the Leman A hub.
Leman F & G Decommissioning Programmes
On 12 July 2023, Shell U.K. Limited submitted, for the consideration of the Secretary of State for Energy Security and Net Zero, the draft Decommissioning Programmes for the Leman F & G facilities in accordance with the provisions of the Petroleum Act 1998. It is a requirement of the Act that interested parties be consulted on such decommissioning proposals.
Leman F & G are two Normally Unattended Installations tied-back to the Leman Alpha Complex, located in Block 49/26 of the Southern North Sea. The platforms are 48km and 51km from the nearest UK coastline respectively. The facilities covered by the Decommissioning Programmes are:
- Installations and subsea infrastructure associated with the Leman F Platform, comprising of the platform topsides, platform jacket, production pipeline, power cable and associated stabilisation features.
- Installations and subsea infrastructure associated with the Leman G Platform, comprising of the platform topsides, platform jacket, production pipeline, power cable and associated stabilisation features.
Public Consultation of the Leman F & G Decommissioning Programmes opened 12 July 2023 and closed 11 August 2023. Following Public Consultation, the DPs have now been approved by the Offshore Petroleum Regulator for Environment and Decommissioning (OPRED).
