Framework to Assess System Risks Associated with Offshore Wind Farms in Northern Context

摘要

Europe is the world leader in offshore wind energy. Due to thernEuropean Union’s renewable energy and climate goals and nationalrnlegislation the offshore wind sector will develop strongly in comingrnyears in Europe. In northern sea areas there are special conditions thatrnregulate the risks in design and deployment decisions for wind energyrnproduction. Moreover, in the current floating offshore wind mill designrnconcepts system risks may also vary due to multiple influences ofrnnumerous risk factors in comparison to onshore wind mills. The focusrnin this paper is on system risks of offshore wind farms. It aims to bringrna systematic risk management approach into perspective to supportrnwind farm design and deployment process under challenging Nordicrnconditions. This approach is based on the system lifecycle model, riskrninfluence factors, and generic risk management framework. The overallrnview of the risks inherent in a wind farm project is presented, but thernperspective in this paper is limited to risks affecting system availabilityrnand system safety of offshore wind farms.
