Rope manufacturer Teufelberger-Redaelli has achieved a new Guinness World Record for making world's heaviest steel rope. Its Flexpack steel rope weighs 495.9162 tonnes and has a diameter of 160mm. Its minimum breaking load is 2166mT and the rope is over four kilometres long.

The rope was made at Teufelberger-Redaelli’s facility in Trieste. The manufacturing process spanned seven months and involved over 50 resources in design, procurement, processing, and deployment.

The steel rope’s new design is designed for applications including offshore abandonment/recovery and pipe laying operations The new design optimises all axial and transverse forces to which the rope is subjected, the company claims.

Specifically, this new rope will be used for abandonment and recovery missions on winches with a Safety Working Load of 750/1000 tonnes in subsea operations conducted in ultra-deep waters.
