By analyzing the shoal,narrow voyage area,ship\'s sailing situation and traffic accident in this channel,the corresponding measures to reduce the traffic accident were put forward,so as to warrant the safe navigation in Hai-tan channel.

According to International Regulations for Preventing Collision at Sea and the special condition of these ships,the office on watch should take action to avoid collision in ample time by holding small rudder,ensure safe navigation.

The safety of navigation is of extreme importance with the rapid development of sea transportation.

The quantified elements involved with safety of navigation are achieved by observing the statistic characteristics of ship flow s components,speeds and the actions of collision avoidance to support ship operation.

Analysis of present status of the Pearl River Estuary navigation safety and countermeasures for navigation control;

The risk analysis of navigation safety for the LNG carriers in Shenzhen port;

Based on investigating the data of ship traffic accident in Fuzhou Port,applied the method of formal safety assessment,analysis the ship s safety navigation in Fuzhou Port Minjiang seaward channel,put forward some correspondent risk-control project and decision-making suggestion,will guarantee and promote the navigational safety in Fuzhou Port Minjiang seaward channel.

Particularly,strong winds and huge waves are the most prominent threats to safety navigation.
