The global oil and gas industry is transitioning from metallic to composite pipes, driven by the need for lightweight, corrosion-resistant, and cost-effective materials. Thermoplastic composite pipes (TCPs) are favored for their flexibility, lower installation costs, and resistance to corrosion and fatigue. However, challenges such as low service temperature, sensitivity to radiation, and complex design persist. This study examines the buckling and material failure behavior of TCPs under combined mechanical and thermal loads typical of deepwater offshore operations, utilizing finite element (FE) models with temperature-dependent material properties. It also explores the influence of design factors like fiber orientation, stacking sequence, and layer thickness on failure behavior, offering insights for optimizing TCP design and performance.
