Fatigue Analysis
When to Use This Skill
Use fatigue analysis when:
- Mooring line fatigue - Calculate fatigue life of mooring components
- Riser fatigue - Analyze fatigue damage in flexible and rigid risers
- Structural fatigue - Assess fatigue in hull, joints, connections
- S-N curve analysis - Apply appropriate fatigue curves
- Rainflow counting - Process stress/load time series
- Miner's rule - Cumulative damage calculation
- Fatigue design - Size components for target life
