OWT-13 Hydrodynamic analysis of floating offshore wind turbine foundation - time domain

This course introduces the participants to the Sesam programs for hydrodynamic analysis of floating offshore wind turbine foundation based on time domain methodology.

Description:

As part of the integrated analysis of floating wind turbine, the time domain hydro pressure distribution on the foundation is calculated in Wasim by reproducing the wave and motions in the coupled analysis, and the hydrodynamic loads and the loads from mooring lines and wind turbine are transferred to the structural model for subsequent time domain dynamic structure analysis.  

This course focuses on hydrodynamic analysis in time domain, including creating section model, calculating the global motion responses and transferring loads to structural model. You will also learn the interface between Wasim and Sima/Bladed. 

In this course, HydroD is the main GUI tool, supported by solver Wasim. HydroMesh is used to create the surface Mesh. Xtract is used to view the results graphically, and Sestra is used for the structural analysis.

Learning scope:

The following topics will be covered: 

• Create section model in GeniE 
• Define and perform time domain global response analysis in HydroD/Wasim 
• Transfer loads to structural model  
• Wasim interface with Sima and Bladed 
• Load reconstruction method in Wasim 

The exercise is based on a floating offshore wind turbine foundation in semi-submersible type. 

Target group:

Engineers involved in design, analysis, or verification of floating offshore wind turbine foundation.

Duration:

1.5 days

Prerequisite:

It is recommended that the participants have completed OWT-11 Hydrodynamic analysis of floating offshore wind turbine foundation - frequency domain or are familiar with hydrodynamic analysis.
