Whether you're running hydrodynamic analysis or simple structural analysis, rules and standards are an important part of the process. We will explore how to apply these rules and standards with our Oil and Gas and Maritime colleagues in a 3-part webinar series. In this series, you will learn how to apply DNV-GL rules and standards in Sesam when modeling a semi-submersible, determine design waves and post-process the results.

In our last webinar of the series, we will focus on fatigue screening using Sesam. The global structural analysis will be performed using Sesam and the results post-processed to fatigue screening of the primary structural plating.


  • Run hydrodynamic load transfer (for fatigue)
  • Fatigue screening of the primary structure
  • Sub-modeling
  • Rule-based fatigue analysis

Download our webinar to experience first-hand how we, in DNV -GL, use our tools to design according to our own standards.
