400 tons of oil spilled into the sea due to collision in Qingdao sea area. What is the cause of the collision accident?

1. Extreme bad weather and low visibility are the main culprits. When thick sea fog comes or it rains heavily, nothing can be seen outside the bridge window. Even if it doesn't rain, the moon will be covered by dark clouds, plus strong winds and waves, or the ship will hit a typhoon directly. If there are two or more ships sailing nearby, there is not enough water around to maneuver, so it is difficult to enter. These are irresistible factors. No matter how advanced AIDS such as AIS, radar and GPS have their limitations, the power of nature is irreparable. No matter how diligent your weather forecast is, no matter how well your course is drawn, no matter how loud your whistle and fog horn are, the ship is in good condition. Even if you can stop for two seconds, you can reverse.

Second, the driver's quality is not high and he is inexperienced.

The theory of collision avoidance is actually very simple. Just slow down, stop, reverse or turn, and give up the ship that is in danger of collision or causes an emergency. However, many times, drivers will not come as they wish. Although there are only a few people on board, they are also Jianghu. Many ships need to inform the engine department in advance to make preparations before slowing down or stopping, and the preparation time is uncertain, depending on the ship's condition and the professional level of the engineers. It is true that even a minute's difference may lead to different consequences in a dangerous moment, and this minute is not enough for engineers to go out of the centralized control room on the second floor and open the oil valve.

Third, the ship was not noticed, the judgment or understanding was wrong, the ship was unwilling or unwilling to avoid, the avoidance actions of both sides were uncoordinated, and too many ships were avoided. The common causes of collision accidents are: the crew's quality defects, which are manifested as weak sense of responsibility, poor avoidance skills, listlessness on duty, excessive tension or carelessness when encountering a ship, etc. Look at fault; Do not use or use radar incorrectly; Too concerned about interpersonal factors, afraid to use the host when necessary; Excessive dependence on VHF leads to improper use; The misjudgment of the situation is common in the cross situation when the overtaking ship thinks it is a direct ship. Underestimated the situation and environment at that time and its dynamic evolution, and fell into a dilemma; It is difficult for the duty force to perform its duties, for example, when the ship is crowded or foggy, the captain neither gets on the bridge nor sends additional helmsman; Occupy the route of other ships; Violation of local navigation rules and international regulations for preventing collisions at sea; Slow avoidance; Pilot's operational error; Improper use of safe speed, especially when objective conditions do not allow it; Steering gear, main engine and power supply suddenly fail; Abnormal waterway environment and natural environment; Traffic chaos, etc.
