SGS China was given the contract for steel-wire rope inspection and documentation review on the Bandra-Worli Sea Link Bridge in India.

Forged anchor cups and nuts were checked using the Magnetic Flux Leakage method, used to detect flaws, corrosion and pitting on the surface and sub surface of steel structures.

The quality and reliability of steel wire ropes is crucial to the safe construction and maintenance of a cable-stayed bridge

The non-destructive testing method uses a strong magnet to induce a magnetic field in the material and in areas with imperfections, such as corrosion or missing metal.

This creates a leakage field which helps flaws to be identified and repaired.

Hindustan unveiled the eight-lane, cable-stayed bridge in June.

It is approximately 600m long and 126m high and is comprised of 2,250km of galvanised steel wires weighing 20,000 tons.
