Strohm secures DNV qualification for deepwater TCP flowline

Composite pipe technology company Strohm has received a Statement of Qualified Technology from verification body DNV for its 6-inch EGF-PE pipe, as per the DNV-ST-F119 standard, for use as a flowline or jumper in deep waters.

This major milestone for Strohm is the result of a rigorous programme 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, thermoplastic composite pipe (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.

Ramon Rojas, program manager for Strohm, said: “A huge amount of work has gone into the development of our TCP, so on a personal level it is brilliant to get this qualification from DNV over the line. This is a landmark for Strohm and yet further evidence of the benefits of our game-changing solution.”

“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.

DNV’s Statement of Qualified Technology also assures Strohm’s TCP Flowlines for use in adjacent energy applications, like hydrogen and carbon sequestration.
