How to save yourself when the ship sinks, and how to escape after the ship capsizes?

If you have to leave the boat, be sure to wear a life jacket, try to choose a lower position when diving, and avoid floating objects on the water and jump off the upwind side of the boat. If the boat is tilted from side to side, it should be jumped from the bow or stern. Jump into the water in the best possible position, with your feet together and bent in front of your chest, close to your side at all times, and cross over your life jacket so that your head and neck are exposed to the water.

Doing so is important to maintain body temperature.

1.When you hear the alarm signal of the shipwreck, immediately put on a life jacket and leave the ship in the direction indicated in the emergency evacuation diagram in each cabin. After abandoning ship, you should stay away from the accident boat as soon as possible, as a sinking ship can create a whirlpool and get people involved.

2.Put on a life jacket and prepare for an escape If the person falls into the water and soaks in the icy sea water for a long time, it may cause hypothermia, causing the central body temperature to drop below 35, and the vital organs in the body will be seriously dysfunctional, and the ventricles will fibrillate, which is the main cause of death due to shipwreck. Therefore, it is important to use life-saving equipment rationally, reduce activity in the water, keep your body and mind quiet, and do everything possible to prevent or reduce the loss of body heat.

3.Be quiet. When a ship carrying passengers is in distress, passengers need to remain calm and composed; Obey the instructions of the staff, quickly put on a life jacket, and do not panic, so as not to affect the stability and resistance of the passenger ship.

Swimming should only be considered if you do not have a life vest and cannot catch floating objects from a wreck, or if you have to leave the sinking ship immediately, and if you are close to shore or salvage boats. Otherwise, even if you are quite skilled in swimming, you will only be able to swim a short distance in freezing cold water. 10 In the water, people with good physical strength can swim 1-2 kilometers; It is difficult for the average person to swim 100 meters.

4.Protect the head and take a certain posture to slow down body heat loss. After entering the water, try to avoid immersing the head and neck in cold water, and do not remove the flight cap or helmet.

In order to reduce the surface area of the body in contact with water, especially to maintain several areas with high heat dissipation, i.e., the fossa, groin, and chest, the hands should be crossed in front of the chest and the legs flexed towards the abdomen should be taken in the water. If several people are together, arms can be folded and bodies huddled together to conserve body heat.

5.Send a signal for help, wait for rescue, and do not drink seawater to find food during this time. In case of distress on tropical oceans, rain is often the main source of replenishment of fresh water**.

In case of distress in the polar regions, sea ice is also one of the best in freshwater. In addition, marine organisms such as fish also have abundant fresh water in their eyes and spinal cords, and some water in their flesh.

Although a person can survive for 30 to 60 days without eating or drinking, the food on board should not be taken lightly. You can skip eating for 24 hours after abandoning the ship, and then eat a fixed amount every day to save as much as possible. If you are drifting at sea for a long time, you can catch marine fish and seabirds and collect seaweed to satisfy your hunger when you are short of food.

However, most of the brightly colored marine fish that are covered with spines or smooth and scaleless are poisonous and should not be eaten.

The only way to escape after the capsizing of the ship is to use lifeboats, swimming suits, etc., first to find a way to get out of the capsized hull, and then to escape.

After the boat capsizes, if there is no ready-made pouch or life jacket when floating in the water, you should use the clothes you wear to make a padded bag or life jacket. Large hats, plastic wrappers, raincoats, shirts, chemical fiber or cotton tops with sleeves, etc., can even be used upside down, but care should be taken not to take off all the clothes to maintain a normal body temperature.

The ship was in distress at sea and capsized to sink without a certain amount of time. Passengers need to stay calm and calm when they hear the abandonment warning signal. ​

1. Quickly put on a life jacket and board the deck as soon as possible in the direction of the emergency evacuation diagram in the cabin. ​

2. Obey the command of the staff, wait to enter the lifeboat to escape, do not crowd and push on the lifeboat, and assist the lifeboat commander to quickly row away from the sunken ship. ​

3. When the ship sinks quickly and it is too late to get on the life-saving equipment, you should wear a life jacket, find a floating object that can be carried in a short time, and quickly jump into the sea to escape directly from the outer stairway, outer chord ladder or porthole. ​

4. After abandoning the ship, use the most familiar swimming posture to stay away from the accident boat as soon as possible, so as not to get involved in the whirlpool caused by the sinking ship. ​

5. If you enter the seawater, keep the most labor-saving swimming posture, maintain the temperature of your head, look for available floating objects, observe the direction of the rescue boat, blow the life-saving whistle on the life jacket, slap the water surface or shout loudly to send out the most effective distress signal to attract the attention of rescuers. ​

Put on a life jacket and go up if you have a lifeboat, and if you don't, find something that can float and find a way to get out of the capsized position as soon as possible to prevent the boat from being swept into the water if the boat capsizes completely.

Even if you wear a life jacket, grab a lifebuoy or other large floating object that you can reach, such as planks, tires, etc., do not panic, conserve your strength, actively spend money to save yourself, and take possible measures to attract the attention of the shore or passing boats as much as possible.

If the boat overturns and is frivolous, quickly dive, be sure to remember the seat belt and swimming ring, and then pull the alarm to start the alarm, and then don't move, hold the safety ring safety valve in the water, and then keep a calm mind, write well Freshwater conserves physical strength in the sea, and is ready to be rescued and rescued.

Abstract:A shipwreck is the sinking of a ship in the water, and there are many reasons for the sinking of a shipwreck, which can be roughly divided into two types: subjective reasons and objective reasons. Subjective reasons include errors in the navigation and navigation of the two ships, collision between two ships, etc.; Objective causes include unpredictable bad weather or ocean whirlpools.

So in the event of a shipwreck, how should we save ourselves? First of all, of course, be calm, and then find a life jacket and a lifebuoy and put them all on; Is it best to prepare a survival kit and tools for escape? Let's take a look at the introduction.

1. What are the causes of the shipwreck?

1. Navigation error.

In short, this means adding a device to your boat. It could be rock, ice, reef, logs, or anything else that could damage the surface of a ship, the hull, or the boat. The best solution is to be careful.

Slow down when you see wreckage, especially after a storm. If you see some floating, there must be more objects beneath its surface. If it sounds like you've hit something, stop the boat and check for holes or cracks.

Tighten the plugs on the drain pipes and read ahead of time what kind of equipment is safe on board.

2. Inclement weather.

The sea is not as calm as you think, and in the event of bad weather such as seaspouts, ocean whirlpools, typhoons, etc., you can only ask for more blessings. If it's unfortunate, it's only a wreck.

3. The two ships collided.

If there is a marine accident in Qingwu, it is normal for a ship to wreck, especially if you hit a large ship that is many times larger than your own ship.

4. Occurrence of ** or unpluggable loopholes.

If there is a serious ** or oversized vulnerability on the ship, then even if there is a watertight compartment, the effect is not great, only the shipwreck.

2. Self-rescue methods in the event of a shipwreck.

1. Don't panic and obey the command of the ship's staff.

2. If there is a life jacket or lifebuoy on the boat, it should be worn quickly. If there is no life jacket or lifebuoy, the hull of the boat or other objects that can float should be used as lifesaving equipment.

3. When the boat begins to capsize, do not huddle together, it is best to disperse the evacuation boat, swim to the shore, island or other rescue life (rescue boat, etc.).

4. If you are shipwrecked at sea, you should be careful not to drink seawater. Because seawater contains a lot of salt, and the human body needs very little salt; If there is too much salt in the body, the excess salt is excreted by the kidneys in the form of urine. If too much water is excreted, it may cause severe dehydration.

At this time, efforts should be made to find fresh water sources (such as rainwater, fresh water pools on the island, etc.) to replenish the needs of the human body.

5. Food for hunger should not be neglected. There are many foods in the ocean that can satisfy hunger, such as fish, seabird eggs, turtles, sea snakes, etc., and you should try to catch them.

6. It is very important to establish confidence in survival, and encourage each other among people in distress.

7. For people who often take boats, it is best to learn to swim and bring a life-saving item when traveling. As the saying goes, you can't walk by the river without getting your shoes wet. On weekdays, it is necessary to establish safety awareness and exercise survival skills.

When time permits, I put on a life jacket and fill my bag with food and water that I can hold on a life raft. If there is not enough time, try to bring resources, if it is really a critical moment, I will jump ship directly, but this should not be, in my own opinion, the vigilance is still very strong, will be completely prepared at the beginning, take the life raft The main thing is to go to the nearby islands to survive first, if you can't find the island, the rescue team fails to find us in time, then I will be directly crunchy.

Put on a life jacket, follow the crew's commands, and most importantly don't panic.

Shenyang Hongbang diving operation service **** wreck salvage method and salvage process are as follows:

1. Sealing and pumping salvage method. After the wreck is broken, the water in the ship is pumped out to make the ship float, because it is difficult to seal and repair, and it is difficult to operate when the wind and waves are strong, so it is rarely used.

Second, the pontoon salvage method. After inflating the underwater with a number of pontoons, the wreck floats out of the water by buoyancy, and this method is buoyant and reliable, and the construction is convenient and safe.

3. Ship skid salvage method. Use steel cables to carry the bottom of the wreck, and lift the wreck with the lifting equipment on the salvage ship, and generally use two or more salvage ships to work together during salvage.

Fourth, foam plastic salvage method. The closed-cell foam with light specific gravity is injected into the wreck cabin, the seawater is discharged, and the ship is lifted by foam buoyancy, which avoids the inconvenience of threading the steel cable at the bottom of the wreck, and reduces or eliminates the sealing work, and is also suitable for operation under the wind and waves at sea.

Fifth, cofferdam salvage method. When the ship sinks in the water area with a small water depth, a weir can be built around the wreck, the water in the weir can be pumped out, the wreck is sealed or repaired, and the cofferdam is removed after the ship is floated by filling with water.

Sixth, inflatable drainage salvage method. It is to inject compressed air into the wreck cabin and discharge the water body, so that the wreck floats. In different cases, different methods of salvaging wrecks can be employed.

For example, for sunken ships and sunken objects that are sunk in rivers or shallow waters offshore, the recovery buoyancy method can be used to salvage. For shipwrecks and sunken objects sunk in the open sea or deep waters of the ocean, the floating dock salvage method can be used to salvage. For the salvage of smaller ponds, the cofferdam salvage method can be used.

For the sunken ships and sunken objects that cannot be salvaged as a whole, they can be salvaged by underwater dismantling and salvage.

7. Crane lifting method, for smaller vessels, divers can be taken to the bottom to fix the hanging point, and the crane can be lifted directly, but it should be noted that because many shipwreck sites are mostly waters, many land cranes are difficult to approach, and even need to carry out the leveling work of the road before lifting the operation.

8. Blasting method, if the wreck has no salvage value, such as a cement carrier and occupies the channel, it does not need to be salvaged, and it can be blown up directly in the water with explosives to clean up the channel. Shipwreck salvage is a diving engineering operation to salvage objects sunk in water. Including diving and salvage ships, aircraft, cargo, etc.

Salvage operations in waterways and port waters can achieve the purpose of cleaning up navigation obstacles. Salvage is a comprehensive technology that involves surveying, diving, underwater cutting, plugging, underwater blasting and underwater welding.
