Preparations Underway for Major Pipe Push

National Grid is preparing for a world record pipe push to replace a major UK gas pipeline.

National Grid is looking to replace the pipeline running 5 km beneath the River Humber, which connects Easington on the East Yorkshire coast to the UK’s national network.

The 42 inch (1,050 mm) concrete coated steel pipeline will be pushed through the recently constructed 3.65 m diameter flooded tunnel at a depth of approximately 35 m below the surface.

Consent for the project was acquired in 2016 and when completed later this year will have cost around £100 million (US$125 million), being Europe’s longest high-pressure gas pipeline in a concrete tunnel.

National Grid is undertaking the operation with assistance from Skanska, A.Hak and PORR.
