Cavotec drag chains drive bridge behemoth
What’s 57 metres long, weighs 200 tonnes and will link a floating hotel with oil platforms? Answer: the world’s longest offshore telescopic bridge. The bridge, built by Marine Aluminium, will be a walkway between specialised accommodation vessel Edda Fortis and oil installations in the North Sea.
This highly specialised unit – powered by our advanced cable chain systems – will initially see service in the North Sea, but is designed to be readily adaptable to a variety of different applications.
The walkway section of the bridge is primarily made from aluminum, with just a 10 per cent steel content, making the structure light but durable.
This is the first time that Marine Aluminium has delivered a telescopic pedestal. It will be mounted on the vessel together with a winch system and can be raised and lowered as required.
Compared to conventional walkways, this bridge requires a large amount of hydraulics and management systems. Our drag chains ensure uninterrupted rotational, vertical and horizontal movement.
