Man-Machine Interactive Ship Maneuver System

The security of maritime traffic is a significant part of maritime transportation. Human plays an important role in it. However, many marine accidents induced by human. Some researches have applied automatic operation system in ship manoeuvre and collision avoidance to reduce accident caused by human. Researchers found that some accidents related to automatic equipment. Automation operation changes the style of working, and forms a new way to make mistake. The paper proposes a man-machine interactive ship manoeuvre system. Man is the main part of system. Computer is an auxiliary facility. Adopt Arena and ship domain method to calculate collision risk and evaluate operation of navigator. If it has high risk of collision or navigator adopts irrational strategy, the system will send warning signal to navigator. Navigator must affirm the messages, if there is not reply, system will adopt collision avoidance and other rational operations at the point of last helm.
