Design your topside on a fixed or floating asset

Sesam is a world-renowned structural engineering software tool for structural design analysis of offshore and maritime structures. Sesam software for topsides provides quick and efficient structural design analysis of steel topside structures. With Sesam software for topsides, the structural design analysis of steel topside structures is fast and efficient. Modelling, load definitions, structural analysis, post-processing and code-checking based on major offshore design standards are performed in the same graphical user environment.

SBM uses Sesam software

The demands are growing. We need software that is flexible in combining beams and plates.

Optimizing the engineering design cycle

  • The Sesam software for topsides covers the analysis of topsides, flare-boom and module – from global beam models to detailed plate/beam models, to refined connections including curved shells
  • The concept modelling technique allows for frequent and significant changes in the design layout or load scenarios without re-modelling – just insert or remove before a one-click operation, creating a revised code-check report based on a new structural analysis
  • The relevant loads are from structural and equipment weight, wind loads, temperature, accelerations and applied loads like point mass and point/line/surface loads
  • Linear structural, eigenvalue, tension/compression only, linear buckling and P-delta analyses may be performed – all based on the Finite Element methodology
  • The offshore code-check standards API/AISC, ISO/Eurocode, NORSOK/Eurocode are supported – the reporting may be graphical or tabular
  • The same model is used from the initial to the final design and through all lifetime modifications – less error-prone, as there is no need for multiple model files
  • The same model and workspace cover multiple design stages, such as transportation, installation and in-place – this saves modelling, analysis and reporting time
  • Sesam is an interoperable tool that can re-use data from CAD or other legacy FE systems – existing data can be the starting point of a Sesam analysis
