What is Fatigue Crack Analysis in Subsea Pipelines about?

This document summarizes a study on crack analysis due to fatigue loads during subsea pipeline installation. The study uses an engineering critical assessment approach to analyze crack growth considering fatigue loads from varying significant wave heights between 0.5-1.8 meters. The analysis finds that allowable defect lengths can decrease by 12.7-25% for external surface flaws and 5.9-13.6% for internal surface flaws as wave heights increase. These results can help optimize allowable defect criteria and im
