A brand new offshore project for Airpes
It is a pleasure to present to you our latest on-demand solution: an offshore project we are very proud of and that has been highly successful.

It’s the design, manufacturing, and testing of a blade counterweight tool for Haliade 150 Offshore turbines.

The client needed a counterweight tool that would provide enough counterbalance torque to rotate the Haliade 150 wind turbine rotor with one or two blades.

A project designed with ALSTOM / GE
For this project, we have worked coordinated with one of the main multinational companies on sustainable mobility and energy sector, ALSTOM/GE.
Blade counterweight tool to turn the Haliade 150 turbine
The counterweight tool is lifted by a crane and bolted to the hub flange. The driving torque is provided by the counterweight located at the end of a boom.

The design of the counterweight tool takes into account the following:

Fulfillment of all specifications
Minimize shipment requirements and assembly time at the site
Optimize the weight of parts and size of actuators
Cost reduction
The blade tool counterweight was manufactured in late 2015 and tested in our facilities in Sabadell, Barcelona, followed by the launch in Nantes, with huge success.

Electro-Hydraulic Control Regulation

With the hydraulic cylinders and the electrohydraulic control; this counter-weight can be adjusted for the different hub positions, ensuring that is capable to be adjusted at any required angle, and changing the weight distance so the torque can be slightly regulated.

Remote Controlled

Thanks to our experience and partnership with AUTEC, this solution has a wide-range remote-controller to ensure that the system is fully-controllable from “Ground”

Certified for Offshore

All inspections approved for Offshore, redundancy, CE Certificates, 3.2 Material Certificate, and Quality Certifications.

Power Supplied by Diesel Generator

Thanks to it’s Diesel Generator, the system can keep running with no problem, without any connection to any electric supply, allowing the autonomy required in the offshore industry.
