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 www.igus.co.uk/EChainInOffshore
