Design your jacket or jack-up

Sesam is a world-renowned structural engineering software tool for structural design analysis of offshore and maritime structures. Sesam for jackets provides structural analysis that includes the load effects from hydrodynamic analysis and non-linear pile/soil analysis. The results allow engineers to assess the structural integrity of an asset, whether this involves deflections, forces, stresses, code-check results or fatigue.

An efficient design iteration process

  • Structural analysis of jackets, jack-ups, subsea templates including their topside, flare-boom and module. From global beam models to detailed plate/beam models, to refined connections including curved shells
  • Concept modelling and automated processes in Sesam support your need for fast design iterations, removing the necessity of re-modelling to create a code-check report on a new structural analysis
  • The relevant loads are from structural and equipment weight, wave, current and wind loads, temperature, accelerations and applied loads like point mass and point/line/surface loads
  • Linear static and dynamic structural, eigenvalue, tension/compression only, linear buckling and P-delta analyses may be performed based on the Finite Element methodology. The loads from pile and soil come from an integrated non-linear pile/soil analysis
  • The dynamic analysis capabilities include stochastic (frequency-domain), spectral (time-domain) and irregular time-domain
  • The offshore code-check standards API/AISC, ISO/Eurocode, NORSOK/Eurocode are supported – the reporting may be graphical or tabular
  • A single model and workspace can be used for all phases from initial to final design, as well as for transportation, installation, modifications, repair and life extension
  • It is possible to import data from other FEA software or CAD systems, allowing you to re-use legacy files
