Pipeline Construction
Land & Marine is one of the four Tier 1 pipeline contractors qualified to design and build National Grid’s high pressure National Transmission System (NTS). Our activities cover the full range of pipe sizes and grades of steel for water, oil and gas systems.
The design and construction of Above Ground Installations (AGI’s) are often critical to the timely completion of pipeline projects and Land & Marine can offer a wealth of experience in this area.
We undertake many pipeline diversions and modifications for a wide range of clients, often requiring under-pressure connections.
Our Engineering Department is experienced in the design of crossings. We have expertise in constructing and installing pipes within tunnels and shafts, as well as the more traditional trenchless techniques.
