Ørsted says offshore UK windfarms need urgent repairs

Operator says it may need to spend 350m over two years to repair cable damage caused by seabed rocks

The Danish wind power firm Orsted has warned that up to 10 of its giant offshore windfarms around the UK and Europe will need urgent repairs because their subsea cables have been eroded by rocks on the seabed.

The renewables firm, which is behind plans to build one of the world's largest offshore windfarms off the coast of Grimsby, told investors it might need to spend up to DKK3bn (350m) over the next two years to repair the cables.
