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...

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...

Transporting components can affect long-term profitability

The owner of a newly commissioned wind project can generally expect a full return of their investment over 20 years. After all, despite the...

Wind will make up a significant portion of the clean energy portfolio

With another record year to the industry’s credit, wind energy deployment both worldwide and in the United States continues to show the effectiveness of...

Equipment shortage possible on a global scale

In the January issue we noted that 2010 promises to be a challenge for the wind power industry as general equipment availability and transport...

Compaction grouting has multiple advantages

When the site of a planned wind tower is underlain by sufficiently dense granular soils, a mat foundation can be designed to safely support...

Loose ground can create foundation design challenges

Soft or loose ground at the site of a new tower can pose challenges to the design of the foundation. Jet grouting can modify...

O&M issues to increase through the decade

By the end of 2010, for the first time in U.S. history more wind turbines will be operating out of warranty than will be...

Wind systems have gotten more effective and reliable

As wind turbines have gotten larger over the last couple of decades, it is difficult to imagine the limitations in size or the future...

Foundation ‘gaps’ can prove costly

Wind power companies routinely face performance issues throughout their supply chains. These functional “gaps” often become problems that can prove very costly. Some gaps...
