摘要：Offshore wind turbines (OWTs) are subjected to different sort of failures due to harsh operation environment. Thus, risk analysis of OWTs is a critical task for making wind energy competitive to conventional sources and achieving the desirable renewable targets. Researches in the field of risk analysis of wind turbines have gained dramatically increasing attention. However, application of risk-based maintenance strategies for OWTs are scare. Risk analysis can be used for selection and prioritization of maintenance activities, and risk-based decision makings have been given increased attention in recent years. This study identifies and reviews the few applied risk-based techniques in literature for maintenance of OWT farms and presents a comprehensive insight for managers into industry 4.0, common influential criteria, risk factors and advanced risk assessment techniques that could be applied for optimal risk-based maintenance strategies of OWTs.
