chainflex® cables for use in the offshore industry

chainflex® cables with "DNV" approval and NEK 606 MUD-resistant approval for maritime use

To allow cables to be used for moving applications on ships and offshore applications without the need for time-consuming and cost-intensive special approvals, igus GmbH and the DNV classification company developed a new test procedure. As a result, a total of 387 chainflex cables from igus have now received type approval for permanent movement in e-chains.
This makes them the first cables in the world specifically for applications in energy chains to receive this approval.

Approvals & standards

The importance of the approvals & standards for chainflex cables

In challenging environments like offshore and marine applications, the reliability and durability of your cables is essential. This is where the MUD NEK 606 and DNV approvals and standards come into play.
These ensure your cables meet the best performance and safety requirements.

Why are these standards and approvals so important?
Both the NEK 606 MUD-resistant and DNV are available in most of our PUR jackets, which means this range of cable are equipped to handle the challenges of offshore applications.
We also offer other cables which are DNV-GL approved in our TPE range.

MUD-resistant according to NEK606

The NEK 606 MUD-resistant standard is a Norwegian technical specification designed for the marine and offshore industry. It covers a range of cables that are MUD- resistant, meaning they can withstand exposure to hydrocarbon-laden drilling mud used in offshore drilling operations.

This resistance is key because drilling mud can have detrimental effects on the cable, which could ultimately lead to cable failures and safety hazzards.

Cables which comply with the NEK 606 standard are tested on their ability to last in harsh conditions with extended exposure to mud at high temperatures.

DNV approvals

In order to supply safe and suitable products for these applications, igus worked with the DNV classification company to develop a new testing procedure and to have their chainflex cables certified.
The DNV is a globally recognised certification body that sets the standards for safety, quality and environmental sustainabilty in the offshore and marine industry.
Cables that are DNV certified have gone through harsh and rigorous testing to ensure they meet the highest standards of safety and reliabilty.

Development of new testing procedures necessary
Classification companies such as DNV typically issue approvals that are in line with international standards. In many cases, particularly concerning the materials, these refer to special specifications with regard to fire behaviour or other requirements.
Over a long certification time of more than three years, with very different areas of investigation, the special knowledge of the two companies led to a cable designation for use in energy chains on ships and in offshore applications for the very first time.
