On March 18, 2013, the "Gwangyang New Port" round sank in Bohai Bay after the last sorrow. In the midst of feelings of impermanence, the reporter recalled what a former senior in the shipping industry had said: the three-point insurance of the horse race. But what is the reason for the tragedies that have caused the tragedies in the Bohai Bay, the "inside door", the only inland bay in the mainland?
Offshore
“It’s strange to say that the more offshore the Bohai Bay is, the easier it is to get into trouble.†An old captain in the interview threw his doubts for many years to the reporter. I heard that this point of view was in doubt, but after reviewing many incident reports, I found that the old captain’s point of view is actually quite objective. In 2007, the "Shenhai 1" round sank in the sea area 20 kilometers away from Lushun Port in Bohai Bay. One person was killed and 15 people were missing. In 2010, "Shangyuan" was in distress in the waters near Dongying Port, and 2 people were rescued and 7 people were missing. The "Gwangyang New Port" round is also confirming this statement. The accident occurred about 40 nautical miles from Shandong Longkou Port.
Why are there frequent incidents in the offshore areas of the Bohai Sea? After combing several accidents, the reporter first saw the clue. First of all, the bad weather in the offshore Bohai Sea is often unpredictable. In 2003, the “Huayuanshun 18†wheel sank in the offshore of Bohai Bay and touched the most painful nerves in the domestic shipping industry. This kind of pain not only comes from the "Huayuanshun 18" round of deception of the competent authorities, but also brought three people on board with the squad, causing three lives to be ruined, and more from the wreck of the 12th gust at the time of the wreck, 10 meters high, but before The weather forecast did not report that the cold air has such strength.
Sudden wind and waves, why can't even the weather forecast be "predictive"? Experts told reporters that this is related to the characteristics of the offshore waters of the Bohai Sea. The extratropical cyclone in the offshore waters of the Bohai Sea sometimes has explosive development, causing the pressure gradient in the Bohai Sea area at the rear of the cyclone to suddenly increase, and the wind power can be increased to 8 to 10 levels with the potential. “This kind of severe weather with regional and sudden features is often very easy to cause ships and weather forecasts to be caught off guard,†the expert said. In the interview, the reporter learned that the main weather systems affecting the navigation of the Bohai Sea have cold air, extratropical cyclones and steering tropical cyclones. The "Huayuanshun 18" wheel sank on October 11th, and the development of strong cold air and extratropical cyclones in the winter half year of the Bohai Bay (October to April). This period is often accompanied by squally waves. At the same time, the complex terrain and tidal activities in the Bohai Sea will lead to extremely uneven distribution of wind and waves. Many factors will cause the ships operating in the Bohai Sea to be at risk during this period. In addition, the captain did not know much about the sailing climate, and “there are countless heartsâ€, which is one of the main reasons for the “Huayuanshun 18†rotation.
The "offshore is not much" in Bohai Bay, is it only in the meteorological aspect? The answer is naturally no. The large environmental disorder in the offshore area of ​​the Bohai Bay is also a major cause of accidents. Take the “Huayuanshun 18†wheel analyzed earlier, the approval stamps used in the two documents of construction drawings and calculations are all forged seals of the Jiangsu Provincial Ship Inspection Bureau, and there are no approved construction drawings at all. The “tofu†ship, which was shoddy in the shipyard, is destined to be close to the sea. Some people may ask, this case has been 10 years away from us. Is the offshore environment in Bohai Bay still so chaotic? I dare not leave the assertion.
In June 2010, “Changxin 218†collapsed along the coast of Bohai Bay, killing 5 people and missing 2 people. A river in the Yangtze River, whose legal shipping area is from Shanghai to Wuhan, why was it killed in the vast ocean of Yantai, Shandong, thousands of miles away? In the after-the-fact investigation, the shipowner admitted that the “Changxin 218†was modified for violence. This includes the welding of the bulkheads, the renewal of the cockpit, the installation of water filtration equipment, etc., because the sea sand pumped on the seabed usually contains water, and these modifications make the ship adapt to sea transport. In order to evade supervision, such ships did not dare to enter Hong Kong even in the face of heavy winds. This phenomenon has further led to the frequent occurrence of offshore accidents in the Bohai Sea.
