THE INFLUENCE OF MULTIPLE WORKING SHIFTS FOR OFFSHORE WIND FARM OM ACTIVITIES – STRATHOW-OM TOOL

摘要

Challenging climate conditions limit the operability and accessibility of the maintenance vessels significantly; therefore,rnthe turbine downtime due to vessel inaccessibility becomes dominant compared to the downtime due to componentrnsupply and actual repair. In the current operational practice, day-to-day operations are performed in single shift basis;rnhowever, considering two working shifts (day and night) can be the solution towards minimised downtime. In thisrncontext, the focus of this research is the investigation of operational and financial benefits that multiple working shiftsrncan bring to the operating offshore farms. The operational simulations are performed by the offshore wind operationalrnexpenditure and logistics optimisation tool StrathOW-OM, which is developed by the University of Strathclyde andrncommercial partner organisations. StrathOW-OM examines climate parameters in the offshore wind farm location, sizernand operational characteristics of the maintenance fleet, and failure rates of the turbine components. The operationalrnsimulations are performed through multiple scenarios in order to identify the most cost efficient solution.
