Maneuverability of Ship Avoiding Collision in Inland Waterway

摘要

With steady growth in the size, the speed, and the number of ships that navigate in inland waterway, 'there has been more crowded, difficult and potentially dangers in inland waterway. Therefore, ship maneuvering in inland waterway is more difficult and more complicated than ever. It is known that when the ship collision accidents occurred, it may lead to the economic and human life losses, irreversible losses in the surrounding environment. It is proved by statistics that all the ship collision accidents are mostly due to the human failure. How to reduce inland waterway ship collision accident evocable by human failure is exigently worth researching. As the related research in Ship Automatic Collision Avoidance System (SACAS), the prediction for maneuvering motion of ship avoiding collision in congested inland waterways is one of important topics. This paper presents the maneuvering motion of ship avoiding collision in different environmental disturbance of inland waterway, i. e. shallow water, wind, current forces. Ships maneuvering of turning, zigzag test are simulated. Meanwhile, the maneuverability, time and angle of turning motion for avoiding collision, are simulated for inland waterway ship. The results indicate that the ship maneuverability in inland waterway would be complicated change to ship avoiding collision maneuver.
