SE-13 Semi-submersible analysis
This course focuses on ULS and FLS analysis of semi-submersibles
Description
This course focuses on design and analysis of semi-submersibles. Modelling the structures for FE analysis and the panel, mass, structure model for hydrodynamic analysis is performed in GeniE. The hydrodynamic environment modelling is performed in HydroD and the hydrodynamic analysis in frequency domain in Wadam.
Hydrodynamic loads are transferred to the FE model for structural analysis in Sestra. Hydrodynamic and structural results are presented in Xtract. ULS code checking of beams and plates is performed in GeniE. Sub-modelling using Submod, and fatigue screening and spectral fatigue analysis of plates/shells using Stofat, are also briefly discussed.
Overall workflow will be managed by Sesam Manager.
