    <subfield code="a">&lt;p&gt;Condition-based maintenance is applied in various industries to monitor and control critical assets and to optimize&amp;nbsp;maintenance efforts. Its applicability to the offshore wind energy industry has been considered for almost&amp;nbsp;20 years and has resulted in the development and implementation of solutions that have contributed to lower&amp;nbsp;cost of maintenance and increased asset availability. However, there is currently no public domain guidance&amp;nbsp;available that provides the information required to (i) prioritize systems for which condition monitoring would&amp;nbsp;generate highest value and to (ii) understand the parameters that need to be monitored by a specific system from&amp;nbsp;failure cause to failure mode. Both items are addressed in this paper, providing a clearly structured, risk-based&amp;nbsp;assessment methodology and corresponding results for state-of-the-art offshore wind turbines. A total of 337&amp;nbsp;failure modes have been identified and analysed by experts representing approximately 70% of the European&amp;nbsp;offshore wind market to assess potential benefits of condition monitoring systems. Results may be used to target&amp;nbsp;the development of condition monitoring systems focusing on critical systems and to find optimal O&amp;amp;M strategies&amp;nbsp;by understanding failure paths of main offshore wind turbine systems resulting in a lower cost of energy&amp;nbsp;and a more optimal risk-return balance.&lt;/p&gt;</subfield>
