In this paper, the methodology for the collision analysis of bridge-vessel was proposed with consideration of the rotational vessel DOF. And it was examined numerically by the estimation of structural responses of the bridge and the vessel. The rotational DOF of vessel was represented by the rotational buoyancy spring. The global responses of bridge were estimated from spring-mass model driven from the first lateral vibration mode. The local structural responses of bridge were considered by the addition of local shell model. The numerical example showed the adequateness and feasibility of the proposed method.
