Country: United Kingdom
Production type: Gas
Project type: Deep offshore
Operator: Total E&P UK (60%)
Partners: DONG E&P UK Limited (20%), SSE E&P UK Limited (20%)
Start date: February 2016
The West of Shetland gas project encompasses the Laggan-Tormore offshore fields, the onshore Shetland Gas Plant and the more recently developed Edradour and Glenlivet offshore fields. Carried out under particularly harsh weather conditions, the West of Shetland project involved the installation of the longest subsea pipeline network ever seen on the UK continental shelf. Used for the first time, the project’s subsea-to-shore technology offers new possibilities in deep offshore exploration.
A three-in-one project in harsh weather conditions
The West of Shetland project is actually three innovative projects combined into one:
- Laggan-Tormore: a 600-meter-deep offshore gas project
- Onshore Shetland Gas Plant
- Edradour-Glenlivet: an extension of the subsea gas project
Subsea-to-shore: meeting the challenges of deep offshore
The West of Shetland project marks the culmination of more than ten years of research and development for Total, with the first-time use of subsea-to-shore technology.
Innovative solutions to preserve the island's natural heritage
To preserve the island’s natural and historic heritage, the construction of the Shetland Gas Plant and its surrounding infrastructure was carried out in consultation with local authorities. As a result, Total decided to remove the peat excavated during construction of the plant and place it in two vast stores, enabling the peat to be preserved over time without releasing any CO2 into the atmosphere. When the plant is decommissioned, the peat will be put back in place, returning the landscape to its natural state. A world first!
