Pipeline end termination (PLET) has been widely used in subsea field development. One challenge in the deployment of a PLET is monitoring the real-time stress condition in different components at different phase. Those components include mudmat, piping pipe system, yoke and upper structure. From load out on a barge to the field, to be settled for normal operation condition as well as recovery process, finite element analysis (FEA) could be utilized to simulate this process, minimize the material cost and optimize the design. The scope of the current paper is to proposal a FEA simulation methodology to analyze this PLET loading process. This basic idea is to use one CAD model with all details to cover the entire simulation process, for all loading phases. The result has been approved to yield reasonable prediction of the real project with major clients. The methodology showed great potential value to be shared with the entire industry. |
