FSI Analysis and Fatigue Analysis of BOP Gantry Crane

Oil and natural gases have been developed, being the most convenient and high-quality resources for human. Offshore plant means design, production, installation, and operation of drilling equipment for natural energy in the deep ocean. BOP gantry crane is the essential equipment of Drilling System Package for drillship/rig. It is used to move BOP stack in drilling platform using BOP trolley. In this research, CFX analysis was used to consider wind pressure, and structure analysis was used to consider dynamic coefficient, rolling, pitching, and self-weight. As a result of crane analysis, even though it is a weight-lightened model, it is observed that the pressure, deformation, and stress value caused by the wind load are stably maintained above those of the previous model. Therefore, the structure is thought to be safe.
