Strohm receives DNV qualification for deepwater TCP flowline

Strohm, the world’s first and leading thermoplastic composites pipe (TCP) technology company, announced that it 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 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, 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.
