NACAP Land & Marine (Oil and Gas)

Opened in November 2007, the South Wales gas pipeline is capable of carrying one fifth of the natural gas consumed by the UK. The underground pipelines are 1,220mm in diameter and 316km in length.

The contractor for the Milford Haven – Aberdulais section was Nacap Land & Marine joint venture. The pipeline continues onto Felindre where there is a compressor station to repressurise the gas.

Around Felindre approximately 1km of 1220mm diameter pipeline was allocated for horizontal directional drill installation. This pipeline was coated with single layer fusion bonded epoxy but required another application of hot applied polyurethane for additional protection through the HDD installation.
