Join us for our next workshop series focused on offshore fixed platform modelling and analysis. 

This workshop will go through the basic modelling, the pile/soil in-place analysis, member and tubular joint code checks, the dynamic spectral fatigue analysis, spectral earthquake analysis and code checks based on API RP 2A for offshore fixed platform structures using software Sesam. 

The following Sesam modules will be used in the workshop:

  • Sesam Manager 
  • GeniE
  • Wajac
  • Sestra
  • Splice
  • Prepost
  • Framework
  • Xtract
  • Version Application Manager

Topics included:

  • Modelling technique 
  • Environmental loads and foundation
  • In-place analysis and code checks
  • Spectral fatigue analysis
  • Earthquake analysis and code checks (Response spectrum approach)

*Please note there will be no workshop on April 19th as our offices will be closed.  

This is a hands-on workshop. We have a number of PC’s that attendees can use, but it is preferred that you bring your own laptop. We will provide a training license for your laptops, but require prior notice. 

Please extend this invitation to anyone in your organization who you believe would benefit from this seminar.

To register simply click the register button and select the dates you would like to attend.  Lunch will be provided at noon. 

We are very excited to offer our expert resources to help you improve skills and efficiency with Sesam. We look forward to seeing all of you in the coming weeks!
