After the incident, the relevant departments quickly launched maritime search and rescue operations, with a total of 7 planes, 246 boats and 498 fishing boats dispatched to conduct a wide range of search and rescue operations on nearby beaches, inshore and offshore areas. Compared with the air crash, the search and rescue operation is more difficult, and this shipwreck rescue also needs to avoid the typhoon, making the rescue more difficult. At 15: 30 on July 4, rescue forces found and salvaged the bodies of 12 suspected drowning victims in an area 50 nautical miles southwest of the shipwreck. At present, relevant departments are stepping up their identification. Hearing this bad news, many people&;s hearts have become a ball. The dead are gone and the living are strong. Now we can only pray that the remaining people who lost contact can return safely and hope that a miracle can appear! In the face of this tragic shipwreck, there are also many different voices on the Internet. Some netizens have raised questions about this: &”;Are these crew members wearing life jackets? Why are you still killed when you wear a life jacket? &”; Some netizens also lamented: &”;When the ship is about to sink, why not jump into the sea to escape in advance?&”; Can a ship escape and save itself by jumping into the sea when it sinks? Since you can work at sea, you must have some swimming skills. Why not swim to the shore? A senior crew member told me that when a ship is wrecked at sea, letting the crew jump into the sea is to push them into the abyss. This kind of behavior is no different, even if a swimmer is in the sea, it will be of no help! At first, I didn&;t believe this statement either. It wasn&;t until the news that the construction ship was killed came out that I realized that the chance of success in trying to save myself by jumping into the sea was almost zero. Even a world-class swimming champion can&;t guarantee 100% unscathed in the sea. Jumping into the sea to save himself is not as simple as we thought. Summer is a period of frequent typhoon weather. According to the weather forecast, Typhoon Siam has moved from north to south, which will affect southern China, Jiangnan and other areas. Now it has moved into Hunan. Although Hunan is not close to the sea, the heavy rainfall caused by typhoon will also make the city soak in rain, which will affect everyone&;s travel. Today, with a deep feeling, we are going to tell you something about this shipwreck. I hope you can learn more about this in your life. When a ship has an accident at sea, can it choose to jump into the sea to save itself? Let&;s look at a real case first. On Children&;s Day in 2015, a sightseeing cruise ship &”;Oriental Star&”; with 454 passengers suddenly encountered a squall line while passing through the Yangtze River Mazhou waterway in Jianli County, Hubei Province. At that time, the wind on the river instantly reached 12-13 and was accompanied by heavy rain. Under the impact of super rain, the cruise ship went backwards, and the hull lost control instantly. After more than 20 seconds, the cruise ship sank at 45 degrees. In less than 1 minute, the cruise ship capsized quickly, and many tourists who woke up fell into the water before they could react. After half an hour, the whole hull sank completely. According to statistics, the &”;Oriental Star&”; has a total of 454 people, including 403 tourists and 5 travel agency staff.And 46 crew members, and most of these tourists are the elderly of the sunset red tour group, generally aged between 50 and 80. As of June 12, according to statistics, only 12 people were rescued and 442 people were killed. The bodies of the victims have all been found, and the search and rescue work has since ended. According to the news reports at that time, many people jumped into the boat to survive without wearing life jackets during the crisis. After these tourists fell into the water, they were washed away by the surging waves before they could save themselves. As for the tourists in the cabin, they finally found a surviving old lady through police search and rescue. From the &”;Oriental Star&”; shipwreck, we can draw a conclusion: even if you jump off the boat, the chances of survival are very small. Even those who can swim will become useless at the moment when they fall into the water. A sailor with 10 years&; experience in living at sea told me that once a ship is in danger at sea or on a river, the safest place is on board, and the chances of surviving without jumping into the sea are even greater. If you jump into the sea directly, the chances of surviving are very slim. This is not alarmist, there is a certain scientific basis behind it, and the reasons are as follows. Many people always think it&;s easy to jump off the boat. Just stand by the boat and jump into the water. This kind of boat is usually the kind of speedboat in the park. It&;s small in size and short in hull. The whole boat may not be as tall as an adult, so it&;s easier to jump off the boat and into the water at this height. But for medium and large ships, it is very unrealistic to stand by the side of the ship and jump into the sea. Let&;s talk about the sinking of the construction floating crane. If the crew members who were killed and lost contact were not forced, it is estimated that no one would want to jump off the ship, because they might also be seriously injured after falling into the water. Floating crane ships, also known as engineering ships, are mainly used for water lifting operations. These crane ships are generally huge, and the gap between the highest point and the lowest point of the ship is very large. To put it bluntly, jumping into the water from a ship is no different from jumping off a building. For example, the 7500-ton full-slewing crane &”;Blue Whale&”; has a total length of 241 meters, a width of 50 meters and a depth of 20.4 meters. The whole ship is equivalent to the size of a football field, and its height is more than 7 floors, while the peak of &”;Blue Whale&”; can reach up to 130 meters, which is equivalent to the height of 40 floors, and the maximum lifting height can reach 110 meters. Even if you jump into the water from the deck, the height of the ship&;s deck from the sea is about 8-10 meters, which is equivalent to the height of a three-story building. Ordinary people without special training jump into the sea directly from here, and they are not dead or disabled. Don&;t think that diving is an easy thing to do. The seemingly gentle water actually kills people. Under the action of gravity acceleration, people jump directly into the sea from the ship. If there is no standard entry posture, if the contact area between the body and the water surface is too large, the endurance of the body will become great, and the water surface will directly shoot people seriously. For ordinary people who have no diving experience and even can&;t swim at all, diving is tantamount to behavior. Even divers will be &”;patted&”; with different degrees of wounds by water pressure when they jump down from a platform of tens of meters high, let alone ordinary people. Secondly, when people quickly fall into the sea, this huge impact willIt hurts people&;s health seriously. Wang Zheng, a swimming coach of Capital Institute of Physical Education, said in an interview with reporters that divers don&;t wear goggles because they are specially trained. For those who have not been professionally trained, imitating diving will only cause eye damage, and if the diving posture is wrong, the stomach will hit the water first when falling into the water, which may hurt the internal organs and even lead to fatal consequences of internal organs rupture. For example, when sailors on foreign aircraft carriers conduct diving training, they will hold their watches, watch the time and start counting from the moment when the sailors jump. Once the sailors&; diving time exceeds, the instructors will immediately go into the water to save people, because these diving soldiers are either stunned by the water or drowned. The endless sea seems calm, but in fact there are countless reefs and some unknown objects hidden under the sea. The reason why the Titanic sank was because it hit an iceberg, which directly led to the hull flooding. At high tide, the hard rocks in the sea are submerged in the sea. Only at low tide, after the sea recedes for several kilometers, these rocks will gradually emerge from the sea. When the ship has an accident, it seems that we jumped into the water from the ship, so we probably didn&;t enter the sea at all, and we may hit the rocks hard at the moment of falling into the water. Some large ships are not very regular in appearance, so when jumping into the water from the ship, they may collide with the hull. Under the action of gravity acceleration, this collision may directly cause fractures. Imagine that the chances of survival are almost zero when the body is fractured and injured without a life jacket. You should know that jumping off a boat would have to bear certain life risks. If the propeller of the ship is still in operation during jumping off a boat, it will produce certain eddies around it. Once it falls into the water and approaches these eddies, it will be directly sucked in. Even people who can swim will find it difficult to escape if they are caught in the whirlpool. Moreover, if these eddies push people into the propeller rotating at high speed, the consequences are really unimaginable. Just like an aircraft carrier, the propeller may be as high as two stories, so we see on TV that there is a long trail behind the aircraft carrier, and the water at the stern of the ship is particularly strong. When the aircraft carrier is moving, it will also produce a lot of vortices around the hull. Therefore, if the aircraft carrier has an accident, the crew may be directly involved in these vortices or even directly involved in the propeller. In 1945, after the sinking of the American Indianapolis, 900 soldiers jumped into the sea, and more than 150 of them were killed by thousands of sharks. Scientists have done experiments. In order to test the olfactory system of sharks in the sea, the staff continuously put diluted blood (bovine blood) into the sea, which soon attracted sharks. An hour later, 41 sharks had gathered in this sea area. In addition to these horrible man-eating sharks, there are many deadly dangers hidden in the sea. For example, there is a carnivorous bacterium in seawater, which can increase the number of Vibrio vulnificus in shellfish (such as oysters and clams). For some people with low immunity, these seafood stab human skin and these carnivorous bacteria will invade the wound; In addition, there is a fungus in the sea, which not only has strong reproductive ability, but alsoIt can quickly produce toxins, leading to human disability, shock and even death. Jack, th《泰坦尼克号》, died of hypothermia. If our body temperature is lower than 95 degrees Fahrenheit (that is, 35 degrees Celsius as we often say) for a long time, it will lead to life-threatening. The average temperature of seawater is 17.4℃, and the water temperature will decrease with the increase of depth. If people soak in the sea for a long time, even in hot summer, the cold seawater will take away the heat of human body and make people die of hypothermia. Maybe many people don&;t believe it. Why don&;t people who swim in winter die of hypothermia when they soak in biting water? Winter swimming and boat jumping are two different things. Winter swimming is strictly time-controlled, usually lasting for a few minutes to ten minutes. It will not be soaked in cold water all the time, and a series of warm-up exercises will be carried out before winter swimming, so that the body can store some heat before going into the water. The preparation work has been fully done, but boat jumping is a sudden act, so how can we have time to do warm-up exercises? Moreover, after the time is up, winter swimmers will go ashore directly to dry their bodies and go to the designated lounge to adapt themselves by alternating cold and warm baths. However, they may not be able to swim to the shore immediately after jumping off the boat. If they jump in the middle of the water again, they will be very far from the shore, and they may lose their temperature and die before swimming. Therefore, if you have to, don&;t jump off the boat easily. Even if you stay on the boat and wait for rescue, your chances of survival will be greater. If you jump off hastily, your chances of survival may be less than 5%. When a ship sinks, is it necessary to sit on the ship and wait for death? Under what circumstances can we choose to jump into a boat to save ourselves? 1, wearing a life jacket and have certain swimming skills, and know the basic skills of survival at sea. It&;s not that we can&;t jump off the boat. If we have to jump into the sea to save ourselves, then the most basic thing is to have a life jacket, so as to at least ensure that we won&;t drown as soon as we fall into the water. In the shipwreck of &”;Oriental Star&”;, there was a survivor who was salvaged and rescued. He said in an interview at that time that he drifted in the river for more than ten hours and finally got help. He survived because he quickly put on his life jacket at the moment he jumped into the boat. In order to prevent the lifeguard from being washed away by the river, he tied it to his belt. Therefore, life jackets are very important at sea, especially for people who can&;t swim, which is regarded as an &”;artifact&”; to save their lives. Secondly, they should know basic swimming skills and survival skills, and try to keep themselves alive when rescue doesn&;t arrive. 2. When a large amount of seawater was poured into the hull, it was impossible to support the rescue. If a lot of seawater has been poured into the ship, and the ship has shown signs of sinking, then we need to jump into the sea and stay away from the big ship before the ship sinks completely and the cabin is filled with water. Otherwise, once trapped in the cabin, even swimmers are easy to suffocate alive, and once the boat is full of seawater, the doors and windows in the boat may not be opened under the reuse of seawater pressure, which will bring great difficulties to escape. Secondly, after the ship sinks, it willForm a huge whirlpool. If we float nearby, the whirlpool will directly suck us in, and we really can&;t live. 3. There is no extreme weather on the sea, and it is not far from the shore. If the sea is calm and sunny, and there is no extreme weather such as super storm, then you can choose to jump into the sea, otherwise it is best to stay on the boat. Secondly, if the location of the sunken ship is not far from the shore, you can jump into the boat and swim back to the shore for further help. Generally speaking, when a shipwreck occurs, there is a certain scientific basis for not letting everyone rashly choose to save themselves by jumping into the sea, especially for those elderly children who can&;t swim. Jumping into the sea to save yourself can only be a &”;last resort&”;. You must not do this unless you have to. Recently, many cities in China have been affected by typhoons and there are many torrential rains. Those friends who work at sea must pay attention to safety and pay attention to prevention. Finally, I hope those lost crew members can return safely!
