Strohm Competing for P&GJ Award for Best Corrosion Technology

Pipeline & Gas Journal Awards judges recently narrowed down a significant number of nominations and announced finalists for its upcoming event Nov. 17.

The program honors the midstream’s leading innovations and outstanding personal contributions to the pipeline industry.

Among the finalists in the Best Coating/Corrosion Advancement Technology award is Strohm BV’s Thermoplastic Composite Pipe (TCP).

TCP is a strong, corrosion resistant composite pipe solution with a long, maintenance free service life. Compared to conventional steel alternatives, it is lightweight and spoolable. It is delivered in long lengths allowing operators to use existing field support vessels on long-term charter rather than mobilizing dedicated pipelay assets, delivering significant efficiencies and supporting lower emissions targets. TCP has a 100% track record of no failures.

To make use of the benefits of TCP in subsea flowline applications, its lightweight nature needs to be counteracted to keep the pipeline stable on the seabed during installation and over its design life. This can be achieved by bundling it with a steel cable, concrete blocks, or coverage by concrete mattrasses. However, these options add technical complexity, installation time and cost.

To resolve this, Strohm has developed an integrated weight coating which provides on-bottom seabed stability. This unique and innovative weight coating is a magnetite filled LDPE plastic that is extruded as an external additional layer to the TCP.

The first fully bonded 2,5-inch ID, 2,200-meter TCP Flowline utilizing this innovation was supplied to Trident Equatorial Guinea last December to support gas lift operations at its Elon-C tie-back offshore the west coast of the Central Africa region.

Strohm has also conducted an analysis of the CO2 footprint related to the manufacture and installation of a TCP Flowline and found that it results in a 50+% reduction compared to that of a steel pipe alternative.

Strohm has also been investing in the development of TCP solutions aimed at CCUS, with a particular focus on offshore subsea pipelines. The main benefits in this sector for using TCP are total elimination of any corrosion, the ability to pull TCP through old pipelines, fast and robust termination in the field and the fact that TCP is a durable pipe, lasting 20 to 30 years. Strohm’s TCP Flowline eliminates corrosion and is the lowest total installed cost solution for greenfield, brownfield and hydrogen applications.
