The Tolmount gas field is a natural gas reservoir and production facility located in the UK sector of the southern North Sea, approximately 36 km east of Flamborough Head, Yorkshire. The Easington Gas Terminal is a crucial onshore processing facility that receives, processes, and exports natural gas from North Sea fields including Tolmount.
STOCKTON GROUP was contracted by energy and offshore engineering leader Saipem to carry out the onshore and intertidal works for the Tolmount Area Development Project, with a gas pipeline installation from the offshore field to the tie-in point within the Easington Gas Terminal.
The Westmoor Reservoir project covers the delivery of reservoir improvement works near Langport, Somerset, which was completed in November 2025. Work was undertaken to ensure the safe and continued operation of the reservoir, keeping the wider water level management system efficient and guaranteeing protection of local communities and downstream towns.
STOCKTON GROUP was brought in help with flood storage in the West Moor and South Moor reservoirs, collectively known as Westmoor. As part of the project, Stockton delivered a 220m trenchless river crossing, using Direct Pipe®, to form a 1400mm I.D. siphon below the River Parrett, to replace the Midelney Siphon.
