The present work presents the design and structural analysis of a subsea rigid jumper, which is a pipe used in oil & gas offshore production. For this to be possible, it was necessary to study standards that contain the necessary calculations to be carried out in subsea rigid pipelines.
After initially defining the geometry, a mathematical model was created according to ASME B31.8 and API 1111 standards, which guarantee a defined wall thickness reliability. In this model, the high pressures which the jumper is subjected to were considered and the selected geometry, resulting in a minimum pipe wall thickness and, therefore, a UC (Unity Check), indicating the feasibility of the selected design.
In addition, a FEM (finite element method) structural analysis was performed on the jumper, using the Abaqus FEA software. To do so, the load condition for which the jumper is subjected were applied, which resulted in the stress field in the pipe. Through a mathematical model developed in the MathCad software, these results were compared and validated with the allowable stresses according to the following codes: DNV F101 (for straight pipes) and ASME B31.8 (for pipe bends).
In order to perform the post-processing of the results obtained in the Abaqus software, it was necessary to use Microsoft Excel and the creation of macros in VBA Excel. With the use of these tools, it was possible to make an extensive analysis, calculating the UC for each node of the mesh created for the jumper. Therefore, it was possible to verify the feasibility of the pipe structure according to the defined methodology.
