At about 2344, the H round of hippocampus touched the T -beam on the upper part of the Lianxi Bridge navigation hole, and the speed of the crash was about 4 knots.

Analysis of accidents

01

The planned route is formulated alone with the depth of water. The investigation found that the captain of the ship had no experience in the inland river of the Pearl River Water. The accident was for the first time to enter the Pearl River. There was no inner river route on the ship. When he formulated the voyage route, the depth of water displayed on the electronic sea map was only taken into the water depth of the electronic sea map, and the data of the bridge of the route was not considered. The net empty height of the bridge and other bridges on the Lianxi Bridge on the route was far lower than the Her wheel of about 15 meters. Improper design.

02

Night ship duty does not meet the requirements. At the time of the incident, the ship sailed at night. Only the captain was on duty at the driver. The sailors did not participate in the duty. Article 25 of the "Rules for the Rules for the Duty of the People's Republic of China Sea Shipweller" "At least one on duty should assist the driver to watch at the time of sailing at night. "Provisions.

03

Not maintaining the deserved alert, negligence, and not discovering the danger of touch in time. At night, the captain was only on duty at the driver's platform and sat in a fixed position for a long time. While the huggly, he also had to observe the planned route on the electronic sea map. With the "5000 tons of ships can go" alone, it is blindly believed that the ship can pass it. It was not until the ship's collision danger of collision between the ship and the bridge was about 200 meters away from the Lianxi Bridge. It was too late.

04

The company's failure to maintain an effective connection and the absolute power of the captain have not been guaranteed. The company did not master the ship's dynamics of the ship, nor did it find that the ship's AIS was abnormal. It was completely unknown to the situation of the ship's accident. Guide to provide guidance from the inland route. The survey found that the boat driver implemented two shifts (6 hours a class, the captain was worth the middle of the night, and the second night). The sailor was not worth the class. The sailor asked for duty and was rejected by sailors. The company did not effectively guarantee the captain's final decision to decide the safety of ships.

Proposal

The planned route of the ship must not only consider the depth of the water, but also consider the net air heights such as bridges and cross -river cables such as the planned routes, and make a good preparations before sailing. The number of data and the ship's own situation can be made in mind, and the design of the ship's route is reasonable, and the safe route is selected. The driver should be familiar with the ship's route and the main points of navigation.

The crew did not take full rest to cause accidents. The shipping company should do a good job in the deployment of the crew to ensure that the crew has sufficient rest and strictly arrange the crew on duty in accordance with the requirements of duty rules. Shipping companies shall take effective measures to determine and maintain the captain's final decision on ship safety and pollution management.

For the sea ships that enter the river, the shipping company should strengthen the education and training of the crew, especially the driver's learning of the driver's main points of manipulating and avoiding the inland river, urge the crew to strictly implement the requirements of the system documents, conduct sailing on duty as required, keep regular looking at, ensure navigation navigation Safety.

Shipping companies should strengthen the dynamic management of ships, maintain effective connection between the ships, grasp the ship navigation plan early, actively collect the relevant management requirements of the competent authority for the characteristics of the ship navigation area, and convey to the ship in a timely manner to provide effective guidance for the ship; strengthen the ship of the ship; The shore -based support provides a complete, accurate and effective navigation book information for the ship, and urges crew to strengthen the inspection and maintenance of navigation equipment such as radar and AIS.
