Cyclic Loading on Monopiles for Offshore Wind Turbines
Today,fixed wind turbines represent the most mature MRE technology.
The foundation of a fixed wind turbine represents 15 to 20% of the total investment and no regulated framework exists for questions of design.
Strong constraints for energy efficiency imply a constant increase in turbine power and directly impact foundation dimensioning where installation and operating efforts are supported (high rotor frequencies and cyclic wave loads).
SOLCYP+, by bringing together the main actors of the sector, proposes to render reliable the methodology for dimensioning monopile foundations in order to optimize costs and toe nsure de-risking of projects through recommendations.
Objectives:
Monopile design for fixed offshore wind turbines-calculations in terms of installation procedures:
- Define a completed and tested methodology in order to progress the applicable norms;
- To understand carbonate sea floors that are currently unknown and frequently encountered on French MRE sites.
Centrifuge tests at 100×g
- Study open ended monopiles instrumented with optical fibers;
- Install monopiles in flight by hammering and load them horizontally without stopping the centrifuge acceleration.
