20 years ago the German government made renewable energies a priority. Especially wind energy became a leading role and experienced an enormous upturn due to the Electricity Feed-in Act. The wind energy utilization is on its way to become the most important renewable energy source. With the “Scientific Measurement and Evaluation Programme“ (WMEP) [1], included in the German subsidy measure “250 MW Wind” and funded by the federal government, the deployment of this technology was monitored over a period of more than fifteen years. The resulting data base of this programme contains a quantity of detailed information about reliability and availability of wind turbines (WTs) and subassemblies and provides the most comprehensive study of long-term behaviour of WTs worldwide. It provides the opportunity to gain basic insights into wind energy and to address larger political questions. Today, the offshore wind energy faces similar challenges as the wind energy on land at the beginning of the WMEP. It can not be considered as assured that the wind energy use up to 100 kilometres off the coast in water depths up to 40metres fulfils the technical and economic hopes. Several years after the erection of first offshore wind farms decisionmakers in politics and in the energy and finance sector will need to rely on detailed information for defining the future of offshore wind energy in Germany. For further development, data and insights on technology and cost developments must be available. Risks in the range of installation, logistic, operation, and grid integration of large offshore windfarms should be minimized by means of verifiable analyses and results. Additionally, a trend to decreasing reliability of large WTs with high rated power and more complex technical concept can be recognized [2]. The availability of different offshore wind farms in UK, Denmark, or Netherlands does not reach in the least the availability onshore of about 97%. Obviously, in terms of reliability and availability the optimization of maintenance processes and component design is urgent. To accomplish these challenges, reliability and availability of WTs for offshore use has to improve and hints at the feasibility and economic efficiency of offshore wind energy are required. The findings of the Offshore~WMEP shall support all players in wind industry and enable the general public to evaluate the offshore wind energy use.
