Scroby Sands maintenance project underway

24 July 2012

On 24 July 2012 Altitec Wind Power Service began a six month project to pro-actively maintain rotor blades on 30 wind turbines at one of the UK’s first commercial offshore wind farms, Scroby Sands in Great Yarmouth, Norfolk.

The development, owned and managed by E.ON UK, was commissioned in 2004 and was one of the first major UK wind farms to receive government approval.  It generates enough energy to supply more than 30,000 homes, saving the emission of 67,082 tonnes of carbon dioxide, nearly 600 tonnes of sulphur dioxide and nearly 200 tonnes of oxides of nitrogen each year.

As part of the proactive maintenance plan, Altitec and E.ON will be trialling Wind Repair Tape and Edge Sealer from 3M, the diversified technology company, on a number of the turbine blades.

Tom Dyffort, managing director of Altitec, said: “The harsh North Sea environment means that over time, tiny objects such as rain, hail and salt spray can cause damage and pit and erode the surface. Non-protected leading edges on rotor blades can have a significant impact on efficiency, increase drag, decrease lift and significantly reduce annual energy production.”

Steven Powell, business manager 3M’s Renewable Energy Division, said: “Preventative blade repair and protection reduces downtime and costs for the asset owner. Research has proven that the 3M wind repair tape helps protect against erosion and ensures the maximum amount of energy is generated from the turbine. Even moderate erosion can have a dramatic effect on the Annual Energy Produced (AEP), reducing it by four to 10 per cent. At the worst end of the spectrum, aggressive erosion can cause delamination which can reduce AEP by 20 per cent. Over the past 15 years, 3M’s renewable energy products have been used across the world on more than 100,000 wind turbine rotor blades.”
