This study focuses on the technical and environmental assessment of submarine pipelines. Utilizing the technical specifications provided in tables, we have conducted a comprehensive analysis of the characteristics of these pipelines. Water pressure analysis indicates that with increasing depth underwater, water pressure also increases. Additionally, modeling of sea currents shows that flow patterns can significantly impact the strength and stability of pipelines.Analysis of temperature and pressure variations also demonstrates that these changes can lead to mechanical fatigue and consequently, structural failure. Based on these analyses, proposing improvement strategies and enhancing the strength and stability of submarine pipelines under variable environmental conditions is crucial.Ultimately, the results of this research indicate that utilizing advanced analytical methods can help improve the quality and reduce the risks associated with submarine pipeline projects.
