1. 1. Major Component Replacement on Floating Wind Turbines

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Kilian Galle; [2023]
   Keywords : ;

   Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE
