At lofty heights: 3D Scan of a wind turbine blade
The maintenance of wind turbines, and whole wind farms, is a challenge. Normally wind turbines are designed to operate for 20 years. During these 20 years they are subjected to all kinds of weather conditions and heavy loads, but thanks to modern acquisition technology and advanced numerical models, such conditions can be addressed and even turned into increased annual energy production. To ...

A Few Things You Should Know about Carbon fibers
Carbon fiber is a new type of fiber material with high strength and with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up organic fibers such as flake graphite microcrystals along the fiber axial direction, and then undergoing carbonization and graphitization treatments. Carbon fiber is a new material with excellent mechanical properties. Its ...

US wind O&M thrust creates new roles, supplier networks
U.S. wind operators will invest in repowering, digital tools and remote technologies in the coming decade, supported by deeper service and spares networks, analysts and suppliers told New Energy Update. The phasing out of the U.S. federal production tax credit (PTC) is set to profoundly impact wind industry spending and employment trends. The 10-year PTC is set at $23/MWh for projects ...

Dust control solutions for wind turbine rotor blade manufacturing
Wind turbine rotor blade manufacturing involves incessant grinding passes that create large quantities of particulate and require innovative dust control solutions. Rotor blades usually range between 30 and 60 meters long. Made by layering thousands of thin filaments impregnated with epoxy resin, the rotor blades have to be reduced to the proper dimensions and prepared to accept the next layer ...

Self-Closing Safety Gates for Regulating Platform Access - Case Study
Semco Maritime is a project engineering company and they needed a safety solution to secure access to specific platforms. These platforms were used as a means by which semco Maritime would transport wind turbine blades. Kee Safety's Self-Closing Safety Gate served as the perfect method of access protection that would keep workers safe and stand up against the elements for the long term. ...

Look what’s cooking in the world of renewable energy
The solar and wind innovations that got us where we are today — and those waiting in the wings — point to a hopeful future. Inside a sprawling single-story office building in Bedford, Mass., in a secret room known as the Growth Hall, the future of solar power is cooking at more than 2,500 °F. Behind closed doors and downturned blinds, custom-built ovens with ambitious names like ...

Performance estimation of HAWT blade using NACA airfoils
Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. The work being presented here is to give new design of blade for VESTAS V82–1.65MW (HAWT). In this work, NACA airfoils are used for the determination of aerodynamic performance characteristics of ...

Wind turbines and health
The American Lung Association's agenda for the new administration, Protect the Air We Breathe: An Agenda for Clean Air, states: "Climate, energy and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming." 1 Wind energy is one such solution - a clean energy source that can ...
