DIS has made verification and strength calculations of an anchor point on service platforms that are used for service and maintenance of wind turbine blades.

                                     

When PP Techniq had to verify the anchor point solution for their service platforms they needed competences they did not have internally in the organization and therefore they contacted DIS for support.

 

PP Techniq has developed an efficient process for servicing and maintaining wind turbine blades both offshore and onshore. By implementing an anchor point on their service platform, it is possible to replace, personnel, equipment and materials on the platform, while it is attached on the wind turbine blade. The very time consuming process of lowering the platform down to the base and returning it to the blade can be avoided when replacing personnel. The solution required strength calculations on the anchor point, allowing technicians and materials to be exchanged with a hoisting system. The calculations were done by DIS.

 

The calculation task included a stress analysis of the entire platform, where high-load areas subsequently were evaluated through analytical calculations and compared with the required standards; DS/EN 795:2012 and Eurocode 3 and 9, where DIS could provide input to PP Techniq’s design based on the calculations.

 

- PP Techniq is a small company where we do not have the necessary resources for such a calculation task. In DIS we found an experienced and dynamic partner who delivered a highly professional solution, says Lars Martensen, Engineering Manager at PP Techniq.

 

The calculations have formed the basis for a weight optimization of the platform and have resulted in a reduction in work hours. Replacement of personnel, equipment and materials used to take 45 minutes, now it takes only 10 minutes.

Lars Martensen informs that the new anchor point solution has been implemented and operates on both offshore and onshore service platforms.

ABOUT PP TECHNIQ

PP Techniq resides in Vojens, where among other they design and produce platforms for wind turbine manufacturers and offer training in the use as well as the maintenance of the platforms.
