With the lower tower section in place, the next phase of the installation involves joining the lower and upper wind turbine tower sections. As with the lower section, both the main and tail cranes were used for the initial lifting the upper tower section until the section was vertical, at which point the main crane took over.

The two pictures below show the point at which the two wind turbine tower sections join. Notice again (below left) the ever present human element, as the upper section is gently guided by human eye onto the lower section. With the upper section swinging ever so slightly in the light breeze, the two sections were brought together with precision and then securely bolted.

With the wind turbine tower sections in place, the nacelle was then lifted (below left) and fixed to the top of the upper section of the tower. The nacelle is relatively small on these turbines owing to the fact that they are direct drive.

The nacelle contains the hydraulic yaw motors and control systems, access to the hub and blades and generator, as well as providing working space for service technicians. The generator will be fixed to the outside of the nacelle, prior to the turbine blades being installed.

 

The picture (below right) shows the nacelle being fixed to the top of the upper tower section. Also visible is the service hatch – strictly for those that dare!

The next phase will be to fix the generator, hub and rotor blades.

Want to install a wind turbine?

If you are in the UK then take our Wind Site Self-Assessment - Step 1 of our modular Windpower Feasibility Study. It takes about 20 minutes to work through the basic checks to see if your site might be suitable, including:

  • Estimating wind speed
  • Checking proximity of nearby properties
  • Checking site access and approach roads
  • Investigating connection with the grid

If you are in the Republic of Ireland, or overseas, the first step is to consider our modular Windpower Feasibility Study, so please Contact us to discuss your site further.
