Sesam GeniE - Usfos software for progressive collapse and accident analysis

Progressive collapse and accident analysis

The Usfos software module is a special purpose non-linear program for progressive collapse and accident analysis of jackets, topsides, floaters and other frame type structures. These structures are often subjected to extreme loads. Accidental damage caused by explosion, fire, dropped objects, extreme environmental events and ship collision poses a major threat to the safety and operation of offshore structures.

What you get with Usfos software

  • Reads the model from GeniE
  • Performs static collapse analysis, non-linear time series dynamic analysis and eigenvalue analysis
  • Predicts both resistance of structures subjected to accidental loads and the residual strength of damaged structures
  • Plastic limit state design allows taking advantage of reserve capacity in the structure
