SE-27 Structural analysis of fixed offshore wind turbine support structures
The course focuses on structural analysis of fixed offshore wind turbine support structures for conceptual and detailed analysis
Description
The course focuses on structural analysis of fixed offshore wind turbine support structures, with main focus on jacket based support structures. You will use GeniE for pre-processer and Splice linearize a non-linear pile-soil foundation, perform an Eigenvalue & dynamic analysis. Use Framework for carrying out fatigue analysis due to waves as well as due to (cyclic) damage equivalent loads. GeniE is used to perform a ULS beam code check based on extreme loads. You will also use Sesam Wind Manager to carry out fatigue and ultimate strength analyses in the time-domain, using time series of wave and wind turbine loads, using a sequential/superelement analysis approach and using an integrated design approach.
Learning scope
You will learn to perform all basic steps of structural and hydrodynamic analysis of a semi-submersible and similar floating structures.
