| description | The safe and efficient transportation of crude oil relies heavily on the structural integrity of
offshore pipelines. However, cracks can form in these pipelines, making it difficult to maintain
them. This study uses computer simulations to examine how multiple cracks behave in offshore
pipelines. By applying a technique called the Finite Element Method (FEM), the research
illustrates how pipelines react under different loading conditions. The study considers important
factors like stress buildup, material properties, and pipe shapes, along with how cracks close
together affect each other. It also uses advanced fracture mechanics principles to precisely predict
how cracks will grow and predict potential pipe fracture occurrences. By varying crack size,
direction, and distance in simulations, the study sheds light on how strong a pipeline is Overall,
the study shows how FEM are valuable for understanding and understanding the problems caused
by multiple cracks. Author is using a ANSYS Workbench 19.2 to simulate the cracks. |
