DNV has released its latest standard, DNV-ST-F207 for hybrid thermoplastic composite flexible pipes (TCPs), which addresses the challenges faced by conventional risers in deepwater applications
TPCs offer a light, ductile, spoolable and corrosion-free solution for transportation of liquids and gases.
The primary objective of the new standard is to facilitate the integration of innovative technologies, such as carbon fiber armour, into flexible riser designs. By incorporating carbon fiber armor elements, risers will become lighter, resulting in lower top tension. Carbon fiber also shows superior resistance to degradation in corrosive environments, common in deep water applications.
By qualifying these technologies and ensuring their adherence to recognised international standards, DNV aims to enhance the safety, efficiency, and sustainability of deepwater projects. The new standard merges different design methods into a unified approach, whereby components are made to withstand different kinds of stresses, and extensive tests will ensure they meet safety standards under specific conditions.
"Overall, this initiative reflects a commitment to advancing technology in the offshore industry, ensuring the highest standards of safety, efficiency, and sustainability in deepwater projects thanks to our expertise and the dedication of our global teams of specialised experts," said Prajeev Rasiah, executive vice president & regional director Northern Europe, Energy Systems at DNV.
