MARKET OUTLOOK: The long and windy road

Getting a wind project up and running can often seem like a pictureless jigsaw puzzle, but streamlining the regulations with new technology and old-fashioned footwork can go a long way to help quicken the process.

It may be easy to look at spinning wind turbines and not be in awe of the plethora of hoops developers have to jump through before an asset ever starts producing power. But regulations are a fact of life for almost any massive project, and wind farms, both offshore and on land, are proving to […]

Lubricate Now, Save More Later

If a lubricant is not considered in a wind turbine’s design phase, it is more likely to experience unexpected maintenance issues as the systems age and components wear.

Wind turbines have been favored in many areas because of their ability to provide communities with environmentally friendly energy. According to Machinery Lubrication, most wind turbines are reliable 98 percent of the time. When they do fail, it is often due to failed or non-existent maintenance. Wind turbines can be expensive to operate, and any […]

Cracking down on foundation cracks

During annual inspections, it’s of paramount importance to inspect foundations every year for cracks as an integral part of proper turbine maintenance.

We all know that the highly engineered foundation is of fundamental importance to the longevity and soundness of a wind-turbine generator. Even so, foundations are all too often overlooked during regular maintenance intervals. Proper maintenance requires that foundations be inspected annually for cracks in the concrete and grout. Major cracks may be a result of […]

The Latest Advancements in Submarine Cables Protection

Undersea cables are vulnerable to many forces — both natural and man-made, so those cables need to be designed and built with additional protection in order to make them resistant and reliable.

Even though hidden deep in the sea and invisible to us, submarine cables are of crucial importance for our daily lives. Undersea cables carry 99 percent of all intercontinental communication, which means that business and private communications, as well as financial transactions, are absolutely depending on their efficiency. Submarine power cables are deployed as well […]

Proper Care and Maintenance of Fall-Protection Equipment

It’s always important to ensure fall-protection equipment for the worker is in top shape, which means systematic care and inspection is vital.

Staying safe while working at height starts on the ground — long before a worker heads up the turbine for a maintenance or repair project. Equipment Inspections Regular inspections are the best way to always be aware of the current state of your equipment. Knowing the products’ condition will allow you to take preemptive action […]

The Rise of the Rescue Kit

With the number of wind-energy workers on the rise, it becomes even more essential that they are equipped with the proper safety tools.

According to Energy.gov, the “United States is home to one of the largest and fastest-growing wind markets in the world.” This growth emphasizes the importance of developing an efficient and effective rescue plan for those working inside and outside of turbines. Rescue kits can be one element of developing a simple and effective rescue plan […]

Monitoring wind turbine oils

Oil analysis and condition monitoring for wind turbines is being done using online sensors.

Most wind turbines tend to be in remote locations, making physical access to the gears, bearings, and control systems difficult and not always practical. Condition monitoring programs for wind turbines generally include time-scheduled oil analysis. Unfortunately, servicing of wind turbines is often limited to specific times each year. When the first large wind turbines were […]

The science behind A superior wear-resistant coating for roller bearings

How Timken engineered ES302, a better way to avoid costly mainshaft and gearbox repairs in wind turbines.

Steel-to-steel contact is why many bearings fail, why proper lubrication is critical, and why The Timken Company, manufacturer of engineered bearings and power transmission components, works hard to develop advanced surface coatings that combat the problem in the toughest conditions. To extend the life of roller bearings operating in wind turbines, Timken developed ES302, a […]

Modern ice detectors for turbines and drones

Turbine ice can be hazardous to people and things, limit energy production, and add stress to blades and towers. Solutions have been complex and expensive – until now.

One ice detector solution for OEMs and operators is to borrow off-the-shelf technology from the global telecommunications industry. Smart phones are manufactured in extremely high volumes around the world. This has forced the price of optical lasers and LEDs down to just pennies apiece. Plastic optical fibers are likewise made in vast quantities, with prices […]

Demand for wind drives record year

Companies thirsty for renewable alternatives, technological advances, and the potential of offshore are just a few of the driving forces that propelled wind energy into a successful and profitable 2018.

American wind power continued to push forward and reach new heights in 2018 — it was a record-setting year for corporate wind purchasing as customer demand for affordable, reliable, and clean energy continued to rise. Technology progressed further and more of the country’s electricity came from wind energy than ever before. That also means more […]

Protecting Wind-Turbine Bearings

Common failure modes can be pre-empted to reduce the likelihood of premature bearing failures.

While wind-turbine functionality relies upon fully operational rolling bearings, these precision components typically will be buffeted by a wide variety of adverse — sometimes extreme — operating conditions and environments. As a result, damage modes can develop, potentially jeopardizing bearing performance and service life and, in turn, a turbine’s reliability and productivity. Fully understanding common […]

Maintaining a maintenance plan

The cost of not applying an adequate O&M strategy at a wind farm can add up quickly.

Even though predictive maintenance has proven its ability to avoid unscheduled stoppages and faults in critical components, there are still many companies that fail to consider new monitoring technologies in their maintenance plans and strategies. Often, predictive maintenance is considered as a cost and not as an investment with return, which is far from the […]
