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 with the result that a total of 387 chainflex cables from igus have now received type approval for permanent movement in e-chains. Therefore, these are the world's first cables specifically made for use in energy chains that have received this certificate.
In order to supply safe and suitable products for these applications, igus GmbH from Cologne worked with the DNV classification company to develop a new testing procedure and to have their chainflex cables certified.
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.
What challenges, what advantages do automation and digitalisation bring to the maritime industry? How can companies meet the strict test criteria to have components certified by competent institutions such as DNV GL? What opportunities arise for suppliers, plant constructors and operators of drilling platforms and ships through the use of certified components such as cables?

NEK 606 is a Norwegian standard for all cables used in offshore applications. 301 chainflex cables comply with the requirements of the NEK 606 standard.
The roller energy chain has been the tried-and-tested energy supply for long travels for about 20 years. The successful design that characterises all our linear energy chain systems is supplemented by rollers made of stainless steel, which upgrade the energy chain to an energy supply for heavy-duty applications. As the energy chain rolls and does not glide, it runs silently and with low vibration. The wear is significantly lower than with a design without rollers, and the power needed for the movement is also about 57% lower.
