‣ Maintenance can only beperformed when turbines areaccessible‣ Accessibility is dependent onweather conditions‣ Weather windows can bewidened with better access andconstruction methods‣ Improve forecasting integratedinto maintenance strategy‣ Improve remote sensing andturbine health monitoring toreport accurate statusWeather Windows
Health MonitoringExample of Alarm Severity Responses‣ Offshore machines will have ahigher value proposition for healthmonitoring technology.‣ Sensor technology is fairly maturebut still needs integration.‣ Wind turbine-specific interpretivealgorithms are needed foractionable responses‣ Establish failure response criteriawith high confidence.‣ Database of HM data shouldidentify long-term strategies fordesign and service.‣ Optimization of repair actions tosave on vessels, labor, anddowntime.
