Independent energy expert and assurance provider DNV (Hovik, Norway) has issued thelatest edition of its Composite components in critical applications, DNV-ST-C501 standard.
The main objective of this standard is to provide an internationally acceptable framework for the design, fabrication, and maintenance of composite components. The goal is to obtain a consistent and appropriate safety level, as well as facilitate the creation of cost-effective solutions.
As the energy industry transition continues, DNV says it is seeing an increasing number of technology developments for which composite materials are an important enabler. This is particularly the case within offshore wind, hydrogen, carbon capture and storage (CCS), and maritime applications.
Composites are made by reinforcing a polymer matrix with fibers like glass or carbon fibers. High-critical applications where composites are used include wind turbine blades, pressure vessels for hydrogen storage, pipelines for the transport of hydrogen and CO2, hulls, and other structures.
DNV continues to stay committed to facilitate the growth in use of composite materials and structures by providing up to date standards and assurance services,” says Philippe Noury, DNV’s principal specialist for energy systems. “The release of this standard is a key milestone towards that prospect. We believe our customers will significantly reduce their costs and environmental footprint by adopting this new revision of the standard in their projects.”
The update incorporates lessons learned from technology developments, which were gained from the assurance of specific applications, joint industry projects, and further research.
Major topics covered in the revised standard include:
- Enhanced test protocols for long term loading;
- Clearer requirements related to high-end carbon fiber reinforced composites;
- Improved guidance related to specific designs, such as risers.
“Technology developments will play an important role in addressing net-zero commitments and pledges towards a Paris-compliant future,” says Prajeev Rasiah, executive vice president for DNV’s energy systems business in Northern Europe.
“No single technology can solve the challenge, rather they will need to work together,” he adds. The update to this standard ensures that industry has choices with respect to materials and technologies in the value chain of a product or solution, together with efficient logistics and implementation practices that can have a significant impact on the absolute GHG [greenhouse gas] emissions in the value chain.”
