North Hoyle

The North Hoyle Wind Farm, located between Rhyl and Prestatyn, 7.9 km off the coast of North Wales, consists of 30 wind turbines with an installed capacity of 2 MW each. The development of the foundation concept for the windmills was challenging due to the soil conditions at this location, comprising mainly condensed sand, sandstone and mudstone. 

Vestas-Celtic Wind Technology Ltd. selected monopiles of 4.0 m diameter as the most secure and economical solution. The installation method chosen was the drive-drill-drive technique, a combination of sequential pile driving and relief drilling. MENCK designed and built special equipment,a pile sleeve, an anvil and an anvil adapter ring for the MENCK MHU 600B hammer to meet the special requirements of this project.

MENCK service technicians were on site to operate the equipment and assist our customer during the installation. Careful planning and teamwork resulted in the pile driving operations being finished ahead of schedule.
