Abstract

This research studied the complex dynamics of subsea pipeline rehabilitation, with a particular focus on the role of composite Fiber-Reinforced Polymer (FRP) in addressing defects of varying sizes, shapes and composite layers applied. The study finds that composite FRP repairs are influenced by defect size, with smaller defects posing challenges. However, the gradual addition of composite FRP layers enhances pipeline resilience, particularly for larger defects. The ideal number of composite FRP layers varies with defect size and irregularly shaped defects may not be effectively repaired with composite FRP. Stress failure patterns show distinctions between defect sizes, with 100 × 100 mm defects exhibiting effective composite FRP performance and 50 × 50 mm defects experiencing premature yield points. These findings highlight the key factors for repair strategies and further research to ensure effective subsea pipeline rehabilitation.
