SCOPE OF WORK
The scope of work includes the following tasks:
- State of the art about fatigue analysis methodology
- Spectral analysis
- Time domain analysis & comparison
State of the art
Analysis of existing methodology.
Spectral analysis
For one typical jacket structure, a ISYMOST/NSO model from existing jacket will be updated to estimate fatigue life, based on classical methodology (spectral analysis).
Time domain analysis
The same structure will be converted into a DEEPLINES model (software developed by PRINCIPIA). It will enable to:
- Check that both models are compliant ;
- Test new Deeplines features for analysis of tubular structures. The intern will be also in contact with software development team to provide feedback/potential improvement ;
- Perform fatigue with more advanced method (dynamic, time domain non-linear…) ;
- Compare results with classical approach and determine potential improvement.
