The European offshore wind farm sector experienced increasing activity during 2011, with a capacity of 866MW brought on-line and another 2.375MW now under construction. The vast majority of the new capacity (752MW) was built in the UK, but the forthcoming pipeline is mainly in Germany – and indeed project finance for the sector was concentrated in that country, with three projects (Meerwind, Global Tech 1 and Baltic 1) raising a record € 2 billion in bank debt, an increase of 40% on the previous year and a demonstration of the country’s ambitious plans gaining momentum.

To enable consumers to make an informed decision when purchasing a SWT, a method for consumer labelling has been developed under the wings of the International Energy Agency (IEA) and the International Electrotechnical Commission (IEC). This labelling method can also be of benefit to professional buyers of SWTs and should spur the industry to develop better products. Some manufacturers of SWTs have already done much of the type testing according to IEC standards, which is required for the label, and expect to apply the label to their products during 2012.

These instruments can be moved from turbine to turbine to perform cost-effective power curve measurements, performance monitoring and the adjustment of turbine static parameters.
