Performance enhancement in wind turbine main shafts using surface coating techniques

Thermal spray and laser cladding coating methods offer strong potential to enhance the performance of main shafts, provided that additive process parameters are rigorously validated and controlled.

Failures in wind-turbine main shaft assemblies (MSA) are an increasing concern in the industry, both for their frequency and the downtime they cause [1, 2]. The rising power density of turbines, driven by competitiveness, has led to higher MSA failure rates and the appearance of defect types not seen in smaller units. This trend is […]

How warranties drive lubricant improvements in the wind industry

Developed as a direct response to customer needs, warranties can reinforce an operation’s stability, productivity, and efficiency, while providing the peace-of-mind that any operation needs to drive the industry forward.

The hard-working technicians focused on wind-farm preventative maintenance face a paradoxical challenge: delivering energy to an industry that prizes reliability and consistency while dealing with conditions that seem diametrically opposed to those goals — extreme temperature fluctuations, exceedingly complex maintenance logistics, and weather patterns that defy expert predictions. That’s exactly why the experts at ExxonMobil, […]

The need for annual turbine oil analysis

An annual turbine oil analysis detects early signs of lubricant degradation and contamination — critical for optimizing turbine performance, reliability and service life.

Although wind-turbine oil could last for 10 years or more, it can start degrading long before that. Given this and because oil is the lifeblood of turbines, regular testing is important. While monthly oil analysis delivers a basic view of the oil’s condition, there are additional tests that should be performed annually to monitor key […]

Cyclic Rating of Wind-Farm Cable Connections

Examining an approach for calculating enhanced ratings for cable circuits connecting wind farms to the grid.

Cable circuits connecting wind farms to the grid are subject to highly variable loading. The sizing of such cables according to conventional continuous rating methods, e.g. IEC 60287, can lead to some conservatism. Traditional daily loss load factors are also unsuitable for use with these circuits, as unlike demand driven circuits there is no discernible […]

Wind Blade Safety: The True Cost of Quality

No single inspection or one-time procedure guarantees blade safety; what protects workers, communities, and assets is the accumulated effect of thousands of quality decisions made throughout the blade’s life.

In the wind-energy industry, conversations about safety often center on tower heights, blade lengths, or extreme weather events. But for those in the field — technicians, inspectors, engineers, and operators — safety starts long before a blade ever turns. It begins with decisions made during design, the precision on the manufacturing floor, the hands that […]

Enhancing turbine lightning protection: A new approach for a new era

As turbines continue to grow taller — and lightning events grow more frequent with climate change — lightning protection system enhancements could become a standard feature for both new builds and retrofit upgrades across the wind-energy landscape.

Lightning is one of the most expensive — and underestimated — threats facing the wind industry today. As turbines grow taller, their vulnerability to lightning strikes is only increasing. The average tip height of these structures has surged from less than 100 meters in 2000 to 164 meters in 2022, tripling the capacity per turbine. […]

Keeping renewables running smoothly

The development of innovative technology will help ensure wind and solar energy operates efficiently and economically as their need continues to grow globally.

Wind-farm operators know that the bolted connections between the hub and rotor blade of a wind turbine are constantly subjected to dynamic loads, leading to stud and bolt failures. To help prevent the possibility of failure, technology is needed to detect broken bolts or studs in the blade root. This system should be able to […]

Components and Technicians: Big parts to play

High in the air, often miles offshore, component experts need a complex raft of skills to serve the wind-energy market.

Dwarfed by a fleet of sky-scraping wind turbines, one might not realize there are up to 20 brakes installed in each one. They are typically rotor brakes and yaw brakes, while, on the electric pitch systems, there are pitch brakes on each drive motor. In the fast-paced, wind-power world, when up-tower, it is important to […]

Drone inspections can prevent million-dollar lightning losses

The shift toward drone-based lightning protection system inspections represents more than just an operational upgrade – it is a fundamental evolution in how wind-energy infrastructure is safeguarded against one of its most persistent threats.

Wind turbines stand as towering symbols of progress in the global renewable energy landscape. However, their height and exposure make them particularly vulnerable to lightning strikes. Each turbine is designed with a Lightning Protection System (LPS) to safely channel electrical energy into the ground, but these systems require regular inspections to remain effective. Without proper […]

Offshore Wind: Cutting costs in half, tripling component life span, and increasing installation rate

New lower weight noncorrosive structural materials and efficient new production methods will result in producing and placing offshore wind turbines at a rate of 50 units per year all at a significantly reduced cost compared to current practices.

Onshore wind has more than 70,800 units in the United States. Unfortunately, onshore wind is not strong enough, nor does it blow often enough, to meet our growing clean-energy needs. Offshore wind is stronger and more consistent, yet there are only seven offshore wind-turbine generators operating. A new process that starts with the signing of […]
