摘要

Motion state of ship out of control in bridge area was analyzed. Motion procedure after losing control was divided into two steps. One is drift step within stopping period. The other is drift step without inertia, which is induced by wind and current. Mathematical model for motion of ship out of control, considering wind-induced drift, current-induced drift, stopping ability, etc., was established. Dangerous collision areas for main pier and auxiliary piers were analyzed according to different calculation conditions.
