An Analytical Assessment of Critical Parameters in Subsea Pipeline Installation: Methodologies, Technical Challenges, and Strategic Solutions
Abstract
The installation and construction of subsea pipelines is a highly complex process, necessitating critical engineering calculation models. Considering that oil and gas reserves are increasingly being extracted from deeper oceanic depths, there is a growing need for new methodologies for the design and analysis of subsea pipelines. This paper investigates the pipeline installation technology in deep waters, highlighting both its advantages and limitations. During the research, international standards such as ASME and DNV were referenced. The calculations were applied to a pipeline with a diameter of 18 inches, examining the dependencies of local buckling propagation pressure, external pressure, and burst pressure for pipelines with varying wall thicknesses at different sea depths. Finally, graphical simulations and a parametric dependence table were developed to illustrate the results.
