STINGER UPGRADE CONCEPT
STINGER FATIGUE ANALYSIS
- Spectral fatigue assessment carried out in frequency domain.
- Stinger & A-Frame models are generated using the software SACS.
- The structural model is imported in MOSES for the calculation of fatigue cumulative damage ratio (CDR), considering appropriate S-N curve.
- Checked for project site conditions (exposure time, metocean data, stinger configuration etc.)
- Stinger Model test in naval basin.
