Vibro compaction is an economical alternative to deep foundation systems

A deep foundation system consisting of a mono-pole or drilled/driven piles is often recommended by the geotechnical engineer when the geotechnical exploration at a...

Bolting techniques, part 2

In the September installment of this column we began discussing various ways to avoid turbine failure resulting from bolt failure and/or improper bolting assembly...

Turbines affect on national security

The siting of a wind farm project can be a lengthy, costly, and a complicated process once a developer takes into account the different...

Bolting applications, part 1

It is never a pretty sight to see a wind turbine collapse. Whether it is material fatigue, defective parts, or severe weather that play...

Next-generation wind turbines will be smarter, more efficient, and more reliable than ever before

According to Wikipedia, innovation is a change in the thought process for doing something, or the useful application of new inventions or discoveries. It...

Achieving successful repowering projects

Renewable energy is certainly living up to its name. To provide greater wind production and lower operational costs, wind farm “repowering” is emerging as...

Remote monitoring allows Q&M professionals to check turbine conditions in real time

Turbine manufacturers typically offer a turbine availability guarantee during warranty at 97 percent, and well-maintained projects with the right technology can achieve levels higher...

Focusing on wind turbine controls

As wind turbines continue to grow in size, reports such as the “DOE 20% Wind by 2030” capture the advantages of larger and more...

Having an emergency logistics plan for replacement components

When you fall ill or have a medical emergency, you know whom to call. It is the same with wind power maintenance issues. When...

A vibrant €”and valuable €”aftermarket

In a post-warranty environment, owners and operators who seek to reduce O&M costs through parts management must begin with an understanding of the cost...

Accurate computer-based design programs are crucial for high system reliability

Wind manufacturers continue to pursue the design and development of larger machines with larger, lighter, and more-efficient rotors. Along with growth in machine size,...

Controlling offshore supply chain costs

Wind farm management, especially offshore, is a matter of economy: generate greater amounts of energy per area, and reduce the cost per megawatt. However,...

The advantages of driven piles

Driven piles can be a cost-effective foundation system for some wind tower sites underlain by loose or soft soils, or mine spoils, which can...

As turbines age, O&M costs increase

Despite a wind turbine design life of 20 years, the likelihood of a corresponding OEM warranty is remote, at least from a cost performance...

All components must first go through a testing phase

As wind turbines have grown in size and capacity over the last three decades, the importance of reliability and technology innovation have been quite...

Many challenges can hit a wind farm project manager

The managers of wind farm projects face many challenges. Risk levels for EPC (engineering, procurement, and constructon) contractors are perhaps among the highest, as...

The technology and concept behind soil mixing

Soil mixing techniques are used to mechanically blend soils in place with cementitious material to improve the soil engineering properties such as strength and...

Turbine reliability a crucial part of success

As the U.S. wind industry begins a trend of increased post-warranty operations, owners are taking aim at turbine reliability as a critical aspect in...

A look at turbine noise

As the industry continues to grow and develop and with wind turbines continuing to be deployed across the nation, the likelihood of wind farms...

Harnessing the power of offshore wind

Offshore energy production is gaining traction as consumption of electricity from conventional sources declines and renewable sources continue to grow. Countries and companies alike...
