Advancing subsea architecture in the production and installation of rigid pipelines

Reeled pipelines

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 in water depths from tens to thousands of meters offshore. 

Rigid pipelines are 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 concealed in the annulus, which may also include active heating cables. 

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

We are experts in the design, assembly and installation of subsea rigid pipeline systems. 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.
