ABSTRACT
ABSTRACT Wind energy is an important renewable energy source. Reduction of the levelized cost of energy (LCOE) for wind turbines are very important in order to make wind energy competitive compared to other energy sources, especially for offshore wind turbines. All costs in the life-cycle as well as the energy produced contribute to the calculation of LCOE. Therefore the turbine components should be designed to have sufficient reliability but also not be too costly, and it is important to include in the reliability assessment the information obtained during operation (from condition monitoring and inspections) and the maintenance performed (incl. repairs and replacements). The paper presents models for reliability- and risk-optimal planning of Operation & maintenance incl. inspections.
