Video of the Week – Offset adjustment for energy chains with FTA

Allowing for lateral offset at the moving end, the floating tow-arm (FTA) from moving energy specialist igus® ensures smooth running of energy chains in a guide trough by floating from side-to-sideto compensate for misalignment in the system. The igus®FTA system is suitable for a variety of applications; in particular for ‘ship-to-shore’ container cranes where the system can accommodates for play in the trolley wheels and rails.

Offering stress-free movement along the entire travel distance, which can be up to 100m, the FTA system extends operational lifetime of the system and can handle speeds up to 2m/s.

Small, lightweight and cost-effective, the FTA system from igus® is compatible with the company’s “PPDS basic” unit for remote condition monitoring; this helps prevent damage and downtime on gliding applications with smaller energy chains.

Ideal steel alternative for cable carrying in harsh environments 


Plastic energy chains from tribopolymer specialist igus are an ideal alternative to steel, which has been the design material of choice for many decades, for working in the harsh environments of the offshore industry. igus e-chains are tougher than steel for a given size and are, of course, much lighter. They are also inherently resistant to corrosion and weathering, and the best types are unaffected by exposure to virtually every type of chemical and petrochemical as well as by exposure to UV light from the sun.

In areas where explosive vapours or gases may be present – that is, those areas where the ATEX Directive applies, as it does to many areas of offshore installations – igus recommends e-chains made of igumid ESD (ATEX material). 


Available in many versions, energy chains provide mutli-directional support for cables that provide power, services and communication to moving systems. Typical applications include drilling crane carriages, rig skidders and link spans.


 igus offers a range of e-chains in different lengths and sizes, including the world’s largest plastic e-chain, the E4.350, with a maximum fill weight of >100kg/m. This e-chain is predominantly used for the movement of large, heavy and stiff cables, such as those used on oil platforms.


In addition, igus holds GL (Germanischer Lloyd) approval for many of its chainflex cables and, specifically for offshore applications, including the CF11.3D and the CF27.D cables with NEK-606 (Norsk Elektroteknisk Komitee) approval are also available, including control cable CF 170 D as well as servo cable CF270.

igus chainflex cables claim a world first as they receive Germananischer Lloyd certification

chainflex product manager, James Harrison, returns to tell us about this important development within the commercial shipping and offshore industries.

Cables for moving applications on ships and within offshore in general would, until now, have needed costly custom certification or design concessions. In response to this, igus has further extended its list of approvals and certifications by announcing that 328 of its chainflex dynamic cables are now certified by DNV GL (Det Norske Veritas and Germanischer Lloyd), the world’s largest ship and offshore classification society.

igus and DNV GL, jointly developed these new industry standards in order to allow dynamically flexible cables to be safely used in moving applications on ships and offshore more generally. This announcement makes igus the world’s first company to offer a full range of dynamically flexible cables, guaranteed for millions of movements and compliant with commercial shipping regulations.

“The approval process for igus chainflex cables took three years and there were many stages to go through before the cables could be ‘Germanischer Lloyd’ certified,” says James Harrison. “But now our customers have the option of buying DNV GL certified control, bus, measurement, data and power cables, specifically for dynamic applications, from stock.”

Harrison explains what this means to igus customers:

‘igus Chainflex customers can now be assured that chainflex cables for dynamic applications, such as power, control, data and bus, comply with commercial shipping requirements. We are really proud of this new development and feel it affirms the high-quality and reliable nature of our products to our customers.’

Corrosion resistant e-chains for the deep

Polymer expert igus has developed corrosion and sea-water resistant e-chains for the use in offshore applications. igus’ e-chains are comprised of a lightweight polymer structure that is used to replace existing heavy steel drag chains. Their low maintenance and long service life make the e-chain ideal for difficult environments or for those hard to access places.

Owing to its polymer structure, the e-chain is UV and sea water resistant, allowing it to provide a heavy duty energy supply to the ocean floor without the need for continued maintenance. The e-chains stability provides a high tensile strength with hanging applications of up to 200m in length, whilst maintaining a flexible modular design that is easy to install. The e-chain comes in various installation applications, including chain-block and e-chain drum versions. ATEX solutions are also available.

igus currently holds the record for manufacturing the largest plastic energy chain in the world, the E4.350. This e-chain is predominantly used for the movement of large, heavy, stiff cables such as those used on oil platforms. Research and development is being undertaken to produce a larger one.

The e-chain is resistant to extreme temperatures, such as those seen on the ocean floor. Typical applications for the e-chain include offshore, drilling rigs and ships and harbours. To learn more about igus offshore applications please go to
