Techniques used in wind park construction

There is both science and math at the core of all rigging techniques. In this installment we discuss techniques used in wind park construction.

Wind park maintenance, as we learned last month, can be quite the rigging challenge. If we focus on the flip side of the coin, wind park construction, we will see that rigging challenges exist here as well. This month we will take a deeper look behind the scenes of rigging. We are going to learn […]

With the increase in megawatt output, turbines and associated components pose maintenance challenges

With the increase in megawatt output, wind turbines and associated components pose maintenance challenges. Here is the second of a two-part series on the issue.

This month we continue our conversation about safe practices for wind technicians. Inarguably, one of the more demanding tasks of a wind technician is to enter a rotor hub and perform any form of maintenance in this small space. An entirely uncomfortable position for the human body, working in such an area where leverage angles […]

Offshore floating turbines offer a compelling means of harnessing the massive resources available in deeper waters

Offshore floating wind turbines offer a compelling means of harnessing the massive resources available in deeper waters, but you must understand the physics that underlie their behavior.

Most utility-scale wind turbines look the same: three blades, tapering in spanwise chord and twist from root to tip, rotor located upwind relative to the nacelle. This apparent convergence of designed form implies a thorough understanding of the aerodynamically-derived forces acting on a wind turbine. In reality, wind turbine aerodynamics are exceptionally complex. These complexities […]

Planning and preparation are critical to any successful project

Planning and preparation are critical to any successful project, but indecision is the enemy of efficiency. Timely decisions keep schedules on track.

The contract is finally signed, and everyone lets out a sigh of relief. Six months of hard negotiations hammered home an agreement. The only problem now is that we only have two months allotted time to start the project ramp up, when even in ideal situations it takes four months. Hey, we got the contract, […]
