Today, structural integrity inspections of wind turbine blades are typically carried out by the use rope or platform access. Since these inspection approaches both tedious and extremely costly, a need for method facilitating reliable, remote monitoring has been identified. In this article, it is examined whether vibration-based damage localization approach proposed authors can provide such reliable location in blade. The blade, which analyzed idle condition, subjected to unmeasured hits from...
Aeroelastic design and fatigue analysis of large utility-scale wind turbine blades have been performed to investigate the applicability different types materials in a environment.

Abstract The commercial-scale deployment of floating offshore wind (FOW) projects is expected to take place in a diverse range sites that may differ significantly from existing fixed-bottom projects. FOW farms are particularly sensitive the water depth and meteorological oceanographic (metocean) geotechnical conditions at project site due wave-induced system motions loads as well anchoring constraints imposed by seafloor conditions. Uncertainty around will permeate through all aspects...
During a turbine’s lifetime, minimizing the cost of power production should be primary aim in addition to attaining high technical efficiency. Thus, this paper was aimed at enhancing aerodynamic efficiency site-specific small wind turbine considering energy as one design parameters. The distribution specific site employed characterize using Weibull method. aerodynamics typical 5 kW blade were investigated by implementing element method (BEM) MATLAB code that applied advancements and...

Abstract Everyone is used to seeing graphs predicting unprecedented growth for the offshore wind industry over next decades. Whether or not these ambitious goals are achieved remains be seen, as it will require nothing less than an industrial revolution in construction and installation. Never have such projections been backed by a global sense of urgency, but unfortunately, just challenge that has met resolved. Data from insurance companies show significant financial losses industry. For...
