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 first webinar of the series, we will focus on modeling in Genie and show the different models used for the hydrodynamic analysis. The hydrodynamic analysis will be explained and demonstrated, along with the post-processed results to include basic motion and accelerations along with design wave selection and global load transfer, according to the various RP’s. Join us to experience first-hand how we, in DNV -GL, use our tools to design according to our own standards.


  • Discussion on modeling
