Calculation specialist on structural load calculations

It is FRECON’s long and successful track-record in design and calculations for wind turbines which is the backdrop of the collaboration with Danhydra A/S and the customers of Danhydra. The company’s solutions are used for the installation and servicing of wind turbines.

Ida Rasmussen, CEO in FRECON:

“Our close and exciting collaboration with Danhydra started back in 2017. In the collaboration with Danhydra we most often did structural load calculations. The majority of our work was performed at our own office, but in close collaboration with the customers. This provides an excellent opportunity to get ongoing feedback from our skilled professionals, which can result in new aspects to a project.”

Examples on calculation tasks for Danhydra:

• Pitch-lock for a leading wind OEM (further development and structural verification)
  A pitch lock is a device used in various repair tasks in a turbine hub, which enables the blades to be locked in place during repair. Additional iterations were needed before the structure was strong enough to be able to withstand the heavy loads that arise during strong winds. Today, the pitch lock has been put into production and operation.

• Calculations on tool to handle extremely heavy loads during blade installation (cogwheel calculations – thinking outside the box was needed). Today, this tool is also being manufactured and in operation at an end customer of Danhydra.
