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
