Pipeline Construction & Repairs

Construction is planned around keeping the line in service wherever the technique allows, so tie-in points, isolation and reinstatement are agreed before any excavation starts. Welding runs to a qualified procedure and every joint is recorded against its own number, which is what makes the as-built traceable years later.

Typical scope: route preparation, stringing and bending; qualified welding and NDT of field joints; tie-ins and hot work under permit; field joint coating and holiday testing; hydrostatic testing and dewatering; backfill, reinstatement and as-built records.
