Oil booms are the primary response equipment for marine oil spill containment, yet their performance is frequently compromised under extreme environmental conditions such as typhoons, storm surges, and strong currents. In this study, a multi-body coupled numerical modeling framework based on computational fluid dynamics (CFD) is developed to investigate the dynamic response of oil booms under combined wind–wave–current loads. The boom is discretized into multiple sectional units, each represented by a six-degree-of-freedom (6-DOF) dynamic model. A dynamic fluid body interaction (DFBI) approach is integrated into the numerical wave–current field to capture inter-segment coupling, elastic connector forces, and the tensile interaction between the boom and the shoreline. The adopted methodology enables the systematic analysis of boom motion response, pressure distribution, and force transmission under extreme sea states. The results provide new insights into the mechanisms of boom fracture, quantify the role of inter-segment coupling in dynamic load sharing, and establish a scientific basis for optimizing structural design and deployment strategies. This research contributes to enhancing the disaster resistance and long-term reliability of oil booms in harsh marine environments.
