Bridging CAD, strength assessment (CAE) and rule-based capacity design

GeniE is a tool for designing and analyzing offshore and maritime structures made of beams and plates.

Modelling, analysis and results processing are performed in the same graphical user interface. The use of concept technology makes GeniE highly efficient for integrating stability, loading, strength assessments and CAD exchange. All data are persistent enabling the engineers to do efficient iterative re-design of a structure.

GeniE for FPSO
Floating structures are normally build up of plates and stiffeners to define necessary steel to carry the loads, enough volume to give buoyancy and compartments to carry liquid or solid ballast. GeniE facilitates very efficient modelling of all these aspects including the loading of such. It will lead to cost savings in the engineering phase since any change in structural, equipment layout or compartment definition (permeability or filling) in the concept model will give an automatic updated and consistent analysis model. In other words, less re-modelling time needed when changes occur.

For floating structures, GeniE can perform static and dynamic linear analysis for structures subjected to wave, wind, current, ballast and equipment layout. The loads and accelerations from the waves and compartment content are defined by HydroD and they are automatically applied to the structure model independent of the hydrodynamic panel model.

Code compliance of beams (typically topsides, modules, flare towers, derricks) may be performed according to API/AISC, API/LRFD or Norsok/Eurocode. The results may be reported graphically or by using standard report layouts that can be customized (supporting MS Office). Similarly, for plated structures (stiffened as well as un-stiffened) they may be checked against codes like DNV(RP C201.1) and API(2U).

The wave loads create input to fatigue assessments of both beams and plates using a stochastic approach. By using the sub-modelling techniques it is very easy to perform a global fatigue analysis to scan for critical areas and make local model for detailed fatigue analysis without the need for time consuming re-modelling.

To efficiently perform the various tasks within design, installation and operation of floating structures, GeniE uses the functionality provided by other Sesam tools as described below.
