Design structures to stand the test of time

While offshore structures are typically designed to last around 20 years, many factors contribute to their actual lifetime. On one hand, time degradation, environmental and accidental loads may reduce structural integrity and the asset's service time. On the other, structural modifications and modern re-qualification methodologies can extend the operational life beyond the original design. For both scenarios, Sesam's Usfos got you covered.

Life extension: see that your offshore asset operates safely beyond design life

Assess older structures for reserve strength and design modifications to extend life safely. Identify the fatigue for the remaining life estimation using modern approaches, and develop a safe operational strategy.

Accident analyses: demonstrate that your offshore asset can operate safely through extreme scenarios

Predict progressive collapse behavior and run accident analyses of space-frame structures - jackets in intact and damaged conditions, for example. Usfos covers extreme and accidental scenarios such as earthquakes, explosions, fires, ship collisions, and dropped objects. 

With Usfos, you perform 

  • Non-linear analysis on subsea template during installation 
  • Wave-in deck analysis on jackets 
  • Progressive collapse analysis of jacket structures with pile-soil interaction 
  • Redundancy analysis of jacket structures 
  • Contact analysis 
  • Ship impact analysis 
  • Blast and fire analysis 
  • Time domain earthquake analysis 
  • Re-assessment of as-built / modified structural design / re-design

SIMPLIFY COMPLEX ANALYSES

EASY TO USE AND EASY TO VERIFY

SKIP THE TEDIOUS WORK

Get it done, hassle-free  

  • Simplify complex analyses: with built-in formulations, Usfos is the only expert in non-linear beam behavior you'll need 
  • Easy to use and easy to verify: set up the analysis in Sesam and visualize the results in a 3D design-oriented, graphical user interface 
  • Skip tedious work: go straight into non-linear analysis using models built in Sesam, or converted from third-party software into Sesam 
  • Combine powerful tools: save time using the time domain temperature loads from KFX when performing non-linear fire analysis 
  • Lower costs: non-linear theories provide a clear picture of structural resistance and residual strength of structures. This enables savings in areas such as inspection planning, life extension, reassessment of ageing structures, boat impact, accidents and fire protection assessments 
  • Optimize new design of OWT and Oil & Gas assets: plastic limit state design allows taking advantage of reserve capacity in the structure
