A blowout preventer (BOP) gantry crane is an offshore plant that moves a BOP stack located on a drilling platform to a BOP trolley. However, such a plant has yet to be developed in Korea. Because BOP gantry cranes produced overseas are expensive, developing such cranes domestically is imperative. In this study, ANSYS was used to conduct a structural analysis on a BOP gantry crane model to simulate the roll and pitch motions of a drillship that were induced by waves and wind load as well as the weight of the crane. Moreover, Simulation X was used for implementing control-system and subsystem designs and to analyze a hydraulic system.
