Export Pipelines

Thermoplastic composite pipes do not degrade or suffer from embrittlement with exposure to hydrogen. Further, as TCP does not corrode, any moisture associated to hydrogen production is not affecting the pipeline. Following the existing globally accepted DNV-ST-F119 standard, TCP will be fully qualified for hydrogen service by the end of 2022 and reach TRL 9 (per ISO/EU commission). Unlike steel pipelines, Tthere is no failure mode associated with hydrogen for TCP (unlike for steel based pipeline technologies). 

TCP, in addition to being very sturdyrobust and perfectly suited for harsh environments, remains lightweight and flexible. It can be delivered in long length and cut to length offshore, maximizing transportation and installation cost. Installation methods are versatile with TCP, from cablelay, to pipelay, to light construction vessels, allowing contractors to propose the most cost effective and safe installation technique. Strohm track record in oil and gas is directly transferable to the offshore wind industry with similar installation methods and the same offshore environment. Strohm has the largest track record in the world!

TCP terminations (end-fittings) can be mounted anywhere, even directly into the platform (floating or bottom founded). This further unlocks cost savings by facilitating the retrofit of existing assets (less load and footprint on the topside, re-using existing J-tubes, …). And it further de-risks the project execution by allowing retermination in case of an incident during operations offshore. Clients’ technicians can be trained by Strohm and be fully autonomous in mounting or remounting end-fittings. 

TCP ranges in internal diameter between 2 inch and 7,5 inch (equivalent to up to 10 inch nominal steel pipe). Maximum pressures can be up to 700 bars for the smaller diameters and 150 bars for the larger sizes, therefore compression is possible to maximize the amount of hydrogen transported and/or reducing the size of the subsea infrastructures. 

Dynamic export pipelines

In case of hydrogen production from a floating unit (FPSO, barge, semi-submersibles, etc), E-TCP can safely carry hydrogen in the harshest and most dynamic environments. The carbon fiber based TCP products developed for the Oil and Gas industry and qualified according to the DNV-ST-F119 standards are perfectly suitable for dynamic hydrogen applications. Unlike other steel based technology, TCP does not degrade or loses its superior characteristics with exposure to hydrogen, retaining its unprecedented fatigue performances. Strohm collaborates closely with the offshore wind to hydrogen industry to propose the most optimized configuration for each projects. 

Data transmission

A fiber optic line can be embedded into the TCP coating to include data transmission without having to lay a separate line, reducing costs and increasing reliability of the system. Indeed, the coating of the TCP provide a sturdy protection to the fiber optic.
