Foundation Installation Equipment – Gode Wind

Seafastening and installation equipment

With the use of jack-up installation vessel Innovation, DEME installed 97 foundations on the Gode Wind offshore wind farm. TWD provided detailed designs for various seafastening structures as well as three supply barges. Furthermore, we designed a monopile upending hinge and seafastening structures for several other items on the vessel.

One of the challenges of this project was accommodating the large weights and lengths of the monopiles and transition pieces. This is because the monopiles used were at that moment the largest and heaviest ever installed in the German part of the North Sea. Despite this challenge, the installation finished more than a month ahead of schedule. Great performance of the installation equipment as well as good weather conditions contributed to the early completion of the project.

Project highlights

• Hydraulically driven skidding system for the load-out of monopiles, moving the monopiles into the crane capacity lifting range
• Stacked monopiles with opening cradle to optimize deck space
• Seafastening structures can accommodate large weights and lengths of monopiles and transition pieces
• Full project cycle – from concept design to fabrication and certification
