||The offshore wind turbine technology is growing rapidly and is an upcoming field in the Non conventional energy resources market.
Risk analysis of mechanical and grid related parts of an offshore wind turbine farm is a topic which has not been studied in depth. In this project an attempt has been made to consider the facts and information available from reliable sources to estimate the probability of failure of different components of the above mentioned aspects of an offshore wind turbine farm in normal and extreme conditions in relation to maintenance. In this project, only the technical risks to the wind turbine or wind farm systems are considered, which means , any incidents which causes financial losses due to repairs / replacements of the wind turbines.
Risk and decision analysis is basically based on the facts and data from reliable sources like wind energy companies and some calculated engineering guesses as the numerical values of probability of certain events are not readily available. This is a limiting factor in the quantitative analysis. Sensitivity analysis of the hazards is implemented in order to understand their importance. In this report all the efforts have been made to collect reliable data from company sources to find interesting results.
In this project, the risk analysis has been extended to various other areas of wind turbine technology. The multi-disciplinary approach includes mechanical parts, electrical system, and the grid connection to wind turbines.
