Wind turbines foundation design
Wind turbines foundation design is an art (and a job) by itself. Here you have a very quick overview of the process for shallow foundation (Patrick & Henderson foundation, widely used in the USA, follow a totally different approach) . The inputs for the foundation design are the result of the geological survey and the…

AutoTURN special transport Nooteboom vehicle library
Here comes my collection of AutoTURN Nooteboom trucks for wind blades transport. I’ve created them starting from several drawings, technical documentation and brochures I’ve found trough the years for the Teletrailer and Telestep. Of course I can’t guarantee they are correct, but until now they have worked – no truck has been stuck in a…

Wind turbines blades materials
A fundamental aspect in the wind blades design is the choice of the correct materials, because several parameters (weight, load and fatigue behaviour, physical properties, etc.) are influenced by this basic decision. Several years ago materials as varied as wood, steel and aluminium where used to produce wind blades. The first wind blades where made…

Wind blade special transport: 45 degrees lifter for montainous roads
This is a blade special transport system that I’ve seen used by Enercon, for instance for Europe highest wind turbine in Europe, in Switzerland, but is not so common otherwise. It is a hydraulic lifter, which allows lifting the wind blade up to approximately 45º. Doing so it can guarantee important saving on the civil…

Liebherr cranes AutoCAD DWG blocks
My collection of AutoCAD blocks of several Liebherr cranes. Special thanks to Ruben for helping me with the conversion from PDF to DWG. You will find different type of cranes commonly used in wind farm projects: cranes for loading and unloading the wind turbine components, auxiliary tailing cranes, cranes for the pre-erection, main cranes (both…

Wind farm standard layout
The components of a typical, utility size wind farm are: One or more rows of turbine perpendiculars to the prevailing wind direction, with a distance between them of 2 or more diameters. For instance, if the diameter of the rotor is 100 meters, the distance would be from 200 to 300 meters. This distance is…

Generic wind turbines 3D AutoCAD Block
Several WTG AutoCAD block – we’ve done them starting from .KMZ Google Earth files freely available imported using PlexEarth, so I don’t know if they are real models (by the way for sure they are not Vestas, although one looks like an Acciona WTG).

Floating roads on peat
Floating roads are a solution developed in Scotland during the construction of several Km of internal wind farms roads on very poor, organic materials such as peat. It is an interesting constructive technology, developed on a very compressible, decayed material normally considered as the worst possible subgrade for road construction. In a normal highway project,…
