Bridon has officially gained world record status for the world's heaviest cable from The Guiness Book of Records for its Big Hydra rope. The cable weighs 337 tonnes (742,957.82 lbs), is 4000 metres (13,123ft 4in) long and was manufactured by Bridon International GmbH (Germany) in Gelsinkirchen, Germany. It was weighed on 6th December 2007. The Certificate can be viewed here.


Ever wondered how loads are accurately and safely lifted to the sea bed in water depths of over 10,000ft? The answer is with specialist low rotation, high strength wire ropes supplied by Bridon and the expertise of deepwater construction companies such as Heerema Marine Contractors.

In support of Heerema’s deepwater operations Bridon International has succeeded in breaking its own world record following the successful manufacture of the World’s largest piece weight of steel wire rope. The single piece was a 4000m (13,120ft) length of 5½” diameter Bridon Big Hydra product with a nett weight of rope in excess of 340 metric tonnes – breaking Bridon’s previous record by 100 tonnes.

The specialist low rotation deepwater handling rope is being supplied by Bridon and its local representative United Offshore Services to Heerema Marine Contractors for use on its deepwater construction vessel Balder. A further 4000 metre length will be supplied later this year along with several specialist crane ropes for the DCV Balder and Thialf.

The single, Bridon Big Hydra rope comprises of over 4.4 million metres of wire spun together to a unique low rotation construction to enable controlled handling while operating in deepwaters. 18 of Bridon’s most experienced employees worked for a period of over 5 weeks to complete the manufacturing. The finished package weighed in at in excess of 370 metric tonnes and measured over 7½metres (24ft) in length. A specialist logistics service was necessary to complete the overnight movement from the factory to the local port in Gelsenkirchen, Germany. The full transport train, comprising of a self propelled modular transporter (SPMT) with 28 axles at each side (each axle with 8 wheels), which measured over 250ft in length brought the town to a stand-still many people coming to watch the overnight entertainment! Using specialist cranes of 1000 tonne capacity.
