An air ambulance has been called out to the Sheringham Shoal Offshore Wind Farm off the north Norfolk coast twice in the last two days.

At 8am today a contractor was injured during a diving operation.

The man was fully conscious and he received medical attention from the onboard doctor before being air lifted to Norfolk and Norwich University Hospital for treatment to a bruised leg. He has been discharged.

Work on the operation has been suspended pending a full investigation of the incident but construction work on the remainder of the site continues as normal.

Yesterday a contractor for one of the wind farm's construction suppliers fell ill due to a non-work related condition onboard the floating hotel 'Wind Ambition' and had to be airlifted to hospital.

He was flown to Norfolk and Norwich University Hospital where he had an operation early this morning, and has now been cleared for discharge.

He will be recuperating with family for a few weeks before returning to work.

General manager for Scira, the compoany running the wind farm Einar Str�msv�g said: 'While this was a successful test of our health and safety procedures, it is a reminder that we must continue to put health and safety at the core of our operations. We wish the contractor a rapid recovery from his illness.'
