Maintenance on the Longoelan wind farm

Client

Vestas

ROLE

Commissioned for lifting works during maintenance on a wind turbine.

LOCATION

Langoelan

DATE

February 2013

CLIENT SPECIFICS

In the perspective of maintaining productivity, Vestas has to keep its wind turbines in good condition. Each component of a wind turbine must be in good working condition, especially the main bearing.

PONTICELLI’S CHALLENGES

The wind turbine must be partially dismantled to change the main bearing. Each blade, the rotor, gearbox and main shaft had to be dismantled and laid down on the ground. Lifting and assembly works were carried out once the main bearing had been changed.

SCOPE

  • Lifting plans by Autocad
  • 3 crane operations for dismantling
  • 3 crane operations for assembly
  • 145 hours of work
