OSC offshore chain
Strongest energy chain - doubly secured - yet flexible
The OSC offshore chain from igus® is used in the toughest conditions, where safety, durability and harsh environmental influences are crucial for the operation of the system. The OSC combines the advantages of a plastic-energy chain with those of a high-strength tension cable, which is guided in both chain links. Tensile forces are absorbed by the plastic fibre rope and transferred to the mounting bracket. The interior separation can be modularly adapted to the project and cable package. The e-chain® offers a bend radius of 750mm for cable and hose.
Tech up
- Modular system, easy to open if necessary
- All components can be replaced individually
- Interior separation can be individually adapted to project and cable package
- Maximum cable diameter up to 80 mm, or 750 mm bend radius

Development of the offshore chain OCS
interior separation
The interior separation of the energy chain can be customised to suit the project and the cables/hoses to be used. The cables are arranged side by side and separated from each other by a PU body (in the form of a comb). The interior separation block is inserted into a steel frame and locked from above with screws and an extender crossbar.
Chain links
The chain links of the OSC are made of a foamed PU material and are therefore impact-resistant. The plastic cable runs inside the chain links and is clamped several times in each chain link. All parts are bolted together and can be secured twice if necessary.
Plastic fibre rope
The high-strength plastic fibre rope absorbs any tensile forces that occur and transfers them to the mounting bracket. This keeps the cable free from any tensile strain. The tension cable can absorb tensile forces of up to 187kN.
Mounting bracket
The plastic fibre cable ends in the two steel connection elements. The strain relief of the cable is also located at this point. The mounting bracket can be screwed to the customer structure using through-holes.

Frequently asked questions
igus® has developed the offshore chain so that cables with large cross sections and high weights can be safely guided in suspended applications. This energy chain is the strongest and most robust energy chain from igus. Specially developed to withstand high cable weights or even wind loads. Due to the installed plastic ropes inside the chain links, the energy chain can absorb tensile loads of up to 187kN.
The new energy supply from igus® is built around a high-tensile plastic cable that absorbs the tensile forces on the system. The rope is made of a synthetic plastic fibre, so it is shatter-proof, weather-resistant, flexible, and corrosion-free. This enables the e-chain to carry tensile loads of up to 187kN.
The e-chain® can be opened from above by loosening the screws on the crossbar. This gives you access to the cable package and you can swap accordingly. Another possibility is to pull the cable lengthwise through the OSC.
The delivery of the OSC chain depends on the chain length. Usually the OSC chain is delivered pre-assembled, with final assembly at the customer's site. Our installation team is happy to take care of the assembly.
All parts of the chain are bolted together and secured and glued with wedge washers. If required, these connections can also be made captive with a cotter pin as a double screw lock.
