Webinar: Introduction to hydrodynamic analysis in offshore engineering

Hydrodynamics is an integral part of the analysis of any offshore structure. The results from the hydrodynamic analysis itself provides important design information, e.g. for investigation of air-gap, accelerations and sectional loads.

It provides the loads due to the waves and wave-induced motions, which can be used as input to the structural analysis.

The hydrodynamic characteristics of the structure are important to account for in a coupled analysis, combining e.g. the effects of waves, wind, current, mooring lines, risers and wind turbines.

Topics covered:

• Basic equations and introduction to Potential theory
• Convergence and meshing 
• Resonances and irregular frequencies 
• Composite model and Morison’s equation
• Demo of hydrodynamic analysis in Sesam software
