TY - THES A1 - Dalir, Amirsam T1 - The main tear and wear cases in off-shore wind turbines N2 - The offshore wind industry is flourishing year by year and the operators are dealing with the respective challenges affecting the lifespan of the offshore wind turbines. For this purpose, a thorough acquaintance with the vulnerabilities and related failure modes in the offshore wind turbine components is the first step to encounter and tackle the problems. However, both the offshore and onshore wind turbines generally experience the same failures, the specific conditions in offshore cases such as salty and corrosive environment, wind gust, etc…, can accelerate these failures and affect the service life of the components. Accordingly, precise investigations of the main failures in the offshore environment are necessary to recognize the causes and mechanisms of these failures and protect the system from them. In this research, the critical failure modes in offshore cases are investigated besides their causes and mechanisms, as well as the most critical components are discussed to determine the share of each of them in the total failure rate for offshore wind turbines.
