First Lean, then modularization: improving the maintenance of offshore wind turbines

Purpose This paper aims to explore how maintenance tasks can be planned and executed in a smarter way and, consequently, how the operations and maintenance of offshore wind power installations can be improved through modularisation. Design/methodology/approach This is a case study of one of Europe’s leading offshore wind power operators with more than 1,000 wind turbine generators in operation. By focusing on this company, in-depth insights into its operations and maintenance processes are investigated. Findings Lean is identified to constitute an important first step before the modularisation of maintenance tasks. The modularisation of the maintenance of offshore wind farms is identified to reduce preventive maintenance times. Practical implications The paper develops a process to identify the resources needed for maintenance before the modularisation of maintenance tasks and resources can take place. The authors also establish a foundation for the development of a software tool to support the development of the modularisation of maintenance tasks. Originality/value The present study contributes to the rather immature field of research on the operations and maintenance of offshore wind power. Furthermore, it adds to the emerging research area of service modularity.
