Case study video: Hydrodynamic optimization of semi-submersibles for better sea keeping performance

The video shows how to improve your semi-submersible for larger air gaps by simulation-driven design. It explains the necessary steps involved in setting up a process chain that allows to automatically optimize the semi-submersible CAD model. In addition the study shows coupling of Sesam CAESES software and Sesam HydroD software, which are used in calculation of shape optimization and sea keeping optimization.

The study shows the general work flow in Sesam CAESES on the basis of a semi-submersible case study. This process is driven by the sea-keeping results provided by Sesam HydroD, which has been coupled with Sesam CAESES ("Simulation-Driven Design").

Both the presentation in the beginning and the following software demo show the "big five" required steps: Parametric Geometry, Pre-Processing, Software Connection, Post-Processing, Shape Variation & Optimization.
