Webinar Series: Applying rules and standards when analyzing structural design

Sesam GeniE software for offshore structural engineering

Explore how to apply rules and standards in Sesam when modeling a semi-submersible, determining design waves and post-processing of the results.

Have you every wondered how rules and standards apply when conducting structural design analysis? If you've asked that question, this is the webinar to attend. 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. 


Webinar 1: May 12, 10:00 am - 11:00 am CST 

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 modelling in Genie and show the different models used for the hydrodynamic analysis. The hydrodynamic analysis will be explained and demonstrated, with the results will be post-processed to include basic motion and accelerations along with design wave selection and global load transfer, according to the various RP’s.   

Agenda:

  • Discussion on modeling
  • Hydrodynamic analysis
  • Rule-based design wave selection


Webinar 2: June 2, 10:00 am - 11:00 am CST

In our second webinar of the series, we will focus on post-processing linear structural results. The global structural analysis will be performed using Sesam and the results post-processed (including yield and buckling check) according to DNV GL rules. 


Agenda:

  • Linear structural analysis
  • Rule-based post-processing of results
  • Rule-based codechecks


Webinar 3: June 30, 10:00 am - 11:00 am CST

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.

Agenda

  • Fatigue screening of the primary structure
  • Rule-based post-processing the results

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


About the speakers:

Chris Kubes, Senior Engineer - DNV GL - Digital Solutions

Chris Kubes graduated from Texas A&M University with an aerospace degree in 2002. He has worked in the aerospace and offshore as an engineer for the past 17 years.

Grzegorz Malinowski, Principal Engineer, DNV GL - Oil and Gas

Grzegorz has 20 years of experience in structural engineering for the maritime and offshore oil & gas industry. His main focus is on Class systematics, design verification/review and independent FE analysis of various steel structures including Ships, Semi-Submersibles, TLPs, Spars, FPSOs, Jackets and Topsides. Currently Grzegorz is involved in Floating Systems Integrity Management, particularly for hull structures. He is a part of the global team within DNV GL to offer a comprehensive Hull Integrity Management service line to industry.
Grzegorz has a M.Sc. from Technical University of Gdansk in Naval Architecture.


Piotr Szalewski, Principal Engineer, DNV GL - Maritime Approval and Verification Center

Piotr is a licensed PE with 20+ years of experience in structural design of maritime ships and offshore floating structures. During his international career Piotr worked in Poland, Norway and South Korea, and since 2011 in Houston. His experience includes classification, assurance and advisory projects at all asset lifecycle phases: conceptual design, engineering, construction, operation, damage remediation and life extension. Over the years, Piotr was involved in development of multiple DNVGL Rules and Standards and IACS Common Structural Rules. He has also developed and lectured multiple technical courses to the industry.
