It gets more and more common to place wind turbines at sea, creating offshore wind turbines. Thus, there is a need for new innovative substructure concepts, including floating platforms, to reduce production, installation and Operation and Maintenance costs for water depths of more than 50 m.

LIFES50+ is a project funded by the European Horizon-2020 programme and it is led by Sintef Ocean, Norway. DTU Wind Energy is leading the activities on numerical modelling and participates in the project. All together 12 partners from the industry, R&D and consultancy sector participates in creating new floating substructure concepts to reduce production, installation and O&M costs for water depths of more than 50 m.

Two new substructure designs
Henrik Bredmose, Associate Professor at DTU Wind Energy says about the project:

”LIFES50+ is a unique project by its competitive setup and well defined focus. At DTU it has given us the chance to develop further our numerical models and also couple them with physical insight. This will be further strengthened by the projects physical model tests. We will use these to validate and calibrate the models. Eventually, the improved models will speed up the design process.

The objectives of LIFES50+ is to optimize and qualify to a Technology Readiness Level – TRL of 5, two innovative substructure designs for 10MW turbines. Further, it is to develop a streamlined and KPI (key performance indicator) based methodology for the evaluation and qualification process of floating substructures.

The focus is on floating wind turbines installed in water depths from 50 to 200 meters.
