Strohm receives “industry-first” DNV qualification for deepwater TCP flowline
(WO) – Strohm, the world’s first thermoplastic composite pipe (TCP) technology company, has taken a big step towards expanding its TCP operating envelope.
DNV has issued a Statement of Qualified Technology for Strohm’s 6-inch EGF-PE pipe, as per the DNV-ST-F119 standard, for its use as a flowline or jumper in deep waters.
It is the first time the verification body has granted an accreditation of this kind, which is testament to the reliability and robustness of TCP under challenging operating conditions.
This major milestone for Strohm is the result of a rigorous program executed across several years in Brazil.
Initial trials got underway in 2018, aimed at applications typical of the region’s post-salt deepwater fields, most of which require pipes connected to FPSOs to be produced.
Almost 40 tests were carried out on Strohm’s subsea flowlines – based on a product design life of 30 years - with changing loads at various temperatures.
Compared to steel pipes, TCP is a strong, spoolable, lightweight and non-corrosive technology, making it ideal for deepwater operations.
As well as being 100% recyclable, it is installed using small vessels or subsea pallets, significantly reducing CO2 emissions.
For Strohm, the Statement of Qualified Technology from DNV builds on existing methodology, material and manufacturing certificates and is a full endorsement of the company’s comprehensive product development approach.
DNV’s Statement of Qualified Technology assures Strohm’s TCP Flowlines for use in adjacent energy applications, like hydrogen and carbon sequestration.
“Strohm’s 6-inch EGF-PE pipe went through very extensive reviewing and witnessing by our Technology Centre in Oslo, and DNV is pleased to be able to provide Strohm with a Statement of Qualified Technology. The Statement of Qualified Technology is based on our standard DNV-ST-F119, which is intended to build trust and confidence in TCPs being safe and reliable for use in offshore service,” said Philippe Noury, Principal Engineer, Energy Systems at DNV.
