Wind speeds change at various heights, making hoisting projects on wind farms particularly challenging

Wind speeds change at various heights, making hoisting projects on wind farms particularly challenging. All the more reason to hire experienced operators.

In past months we have learned about the maintenance process, rigging techniques, and the different crane types relative to the wind industry. This month we are going to take a look into how the wind speeds change at various heights. The wind speed changes can help reduce wear and tear on the wind components in […]

Maintenance professionals can use their physical senses to detect gearbox problems

In addition to the latest technologies, maintenance professionals can use their physical senses to detect gearbox problems, as this first in a two-part series makes clear.

Armed with some experience and a bit of awareness, there are several ways in which a technician can diagnose wind turbine gearbox problems while uptower. Using the physical senses, it becomes relatively straightforward to listen for noises coming from the gearbox, to observe surface damage on the gearing, and to observe the color and smell […]

Uncertainty in the soil properties can have effects on the reliability of offshore turbine support structures

Uncertainty in the soil properties can have significant effects on the reliability of offshore wind turbine support structures with monopile foundations.

While offshore wind turbine technology has evolved from its onshore predecessor, engineering experience in the offshore oil and gas industry has also contributed to the design and analysis methods utilized in offshore wind. In particular, the method utilized in the design of the support structure for an offshore wind turbine (OWT) has its roots in […]
