Latest developments in tower concepts: reducing costs

9:15 am - 9:45 am Reduction of LCoE by a smart tower solution for hub height of 160+ [m]

Different tower solutions and installation techniques are studied for a number of different local conditions. Each wind project with its local conditions is unique and has its own challenges and cost drivers.
Climbing crane solution for a precast concrete tower for hub height of 160 m will be presented as one option
Challenges and benefits of a climbing crane in the international market will be addressed

2:45 pm - 3:15 pm Closing remarks by chairman

3:45 pm - 6:15 pm Workshop A: Challenges of soft towers

This workshop will touch upon the topic of basics and boundary conditions and to find the optimum frequency to reduce the loads. Further vortex vibrations for the first and second eigenfrequency will be discussed and possible solutions for reducing unwanted vibrations will be looked at. Participants have the chance to discuss all these topics in an in-depth discussion.
