Amec Foster Wheeler’s Glasgow upstream team worked on three concurrent projects to provide engineering services during the basic design phase of the Liquid Efficiency, Methanol Removal and Furnace Upgrade projects at Total’s St Fergus Terminal in Scotland, UK. The St Fergus Terminal receives and processes gas from the UK North Sea and Norwegian Continental Shelf via the Frigg UK and Vesterled pipelines, respectively. The gas is then exported to the National Grid plant adjacent to the Total site where it is compressed for delivery to the UK national grid.
Basic engineering for the three projects ran concurrently and we produced the various specifications, 3D models and drawings up to the detail design stage. We also developed the designs for key long-lead equipment items.
With a remote site and limited local resource availability, we maximised off-site working via a modular approach, intended to minimise the impact on ongoing operations at St Fergus.
The objective of the Liquid Efficiency Project was to accommodate increasing Frigg UK throughputs and allow natural gas liquids (NGL) production to be optimised. The Methanol Removal Project involved the installation of new facilities for the removal of methanol from the NGL stream. The Furnace Upgrade Project was intended to provide 20-30 years’ additional design life for the existing furnaces, while the new furnace was planned to provide some redundancy for future operation.
“This award reflects our upstream engineering expertise and our modular design capability. The St Fergus terminal site is well known to us and we have been involved in projects there since the mid-1980s.”
