Rigid pipelines

Advancing subsea architecture in the production and installation of rigid pipelines

 

ETH-PiP Brochure

Rigid pipelines are a fundamental component of subsea architecture, forming the subsea highway that transport oilfield fluids between the wellhead to the processing facility. TechnipFMC procures, fabricates and installs rigid pipelines in all areas of the world and in water depths from tens to thousands of meters offshore.

Rigid pipelines can be made from carbon steel, corrosion resistant alloys or hybrid construction with a carbon steel parent pipe and internal corrosion resistant cladding or lining. The pipelines are coated for external corrosion protection and insulation. Demanding insulation needs are met using a double wall pipe-in-pipe construction with high performance insulation, which may include active heating.

Rigid pipelines range from small diameter 4-inch pipes for oilfield service fluids, to medium diameter 6-inch to 18-inch infield lines, to large diameter export trunk lines connecting offshore processing facilities to onshore receiving facilities.

We offer several rigid pipe products to meet the needs of operators who face a range of challenges from solving flow assurance issues to transporting highly corrosive fluids.

We are experts in the design, assembly and pipelay of reeled pipe‑in-pipe assemblies for static and dynamic riser applications.
