One of the main risks connected to blade maintenance is the uncertainty of wear and tear expenses during the operating lifetime of a blade. As blades constantly are exposed to changing environmental forces, wear and tear on blades varies depending upon site-specific conditions and seasonal & weather changes. These factors make the forecasting of wear and tear costs subject to high uncertainty. To remove this uncertainty Vestas offers the option to include wear and tear as a contractual element.
Even normal operating conditions can lead to wear and tear on blades, which can have a negative impact on your turbine’s performance over time. Typically, repairs addressing wear and tear issues are not part of the standard service agreement coverage, which leaves you having to forecast these unknown costs as part of your annual operating budget. While wear and tear issues might not seem significant, if left unaddressed, these occurrences can have severe impacts on energy production and introduce the possibility of costly, unplanned wind turbine downtime.
The BladeCareTM– Wear and Tear Coverage product offering expands the current blade coverage under your Vestas Service Agreement to include wear and tear items and couples this coverage with comprehensive annual inspections. It enables you to be one-step closer to “full-wrap” coverage on your most exposed turbine components.
