Golden Fishery

  Dear brothers and sisters, if you have a vote, please vote for one. Thank you for the bullet casing! ****

  On the hunter fleet, the captains discussed on the public radio channel:

  "Snow, these **** are crazy! Oh, they are too many people, guys shout, damn, you must get rid of these bastards!"

   "Yes, or we call the police? They must be illegally armed water cannons. Besides, so many of them fired, call the police..."

  "Don’t call the police, idiot, Robin’s boat also has water cannons. The most important thing is that although they fired, don’t you guys shoot? And we still have large-caliber rifles on board!"

  "Stop talking, be careful. There are many hidden reefs in the sea area we are entering now. Be careful not to run aground on the reef!"

  "It’s okay. I walked through here. The reef is not dangerous. Do those **** think this is the Bermuda Triangle? Ha, our boat has such a draught depth, how can it hit the reef..."

   "Boom!" A muffled sound!

   "Fak! Fak! Fak!" Robin's panic roar immediately spread to everyone's ears via radio.

  A group of hunters were stunned. Someone shouted: "Brother Robin, what's the matter?"

  Where is Robin still in the mood to answer? He was planning where he would call his brothers to avenge him. This time he was really lost. Now he still feels hot pain on his skin, and his image is even more embarrassing.

   Suddenly, I was the Pirate Ship, and it seemed that I was hit by something, or hit by something. In short, the hull of the ship shook violently. Immediately several red lights in the cockpit lit up, and the buzzing sound continued to sound.

   "Ohhhhhhhhhhhhhhhhhhhhh!"

  The buzzer sounded harshly, and the ship continued to vibrate.

  Qin Shiou controlled the giant monster. He waited until I, the Pirate, passed over a hideous reef. The giant monster dormant here first chiseled a gap in the bottom of the ship with a mace, then used the warfare of the beacon mace, bombarded the gap one after another, and quickly expanded it into a basin-sized hole.

  More than that. He also controlled the giant monster to wander forward, and opened a big opening in the front of the ship. This opening was bigger than the previous one, creating a scene where the bottom of the ship hits the reef and then the front hits the reef again.

  The turbulent sea roared and got into the hull. Seeing this, Qin Shiou smiled slightly and gave the giant demon an order to let it go. That's it. Hidden merit and fame!

  The two gaps were flooded at the same time, and I, the Pirate, began to sink slowly.

  Modern ships use watertight compartment technology-of course, I am proud to say that this technology was invented by the Chinese and is known as one of the four ancient inventions of navigation. It appeared in the Tang Dynasty and was perfected in the Song Dynasty. This technology was very advanced when Zheng He went to the West.

  The so-called watertight compartment, as the name suggests, is to divide the cabin into separate compartments with compartment plates. In this way, because the cabins are closely separated, even if one or two of the cabins are damaged and flooded, the water will not flow to other cabins.

  From the perspective of the ship as a whole, as long as it maintains considerable buoyancy, the ship will not sink. And there is a watertight cabin buffer, even if the damage is large. Even if there is too much water, the boat cannot hold it. There is also time to reduce the load by abandoning the cargo and support the ship to continue its normal voyage.

  Modern ships have adopted higher technology. After a watertight tank enters the water, as long as the ship does not sink, these tanks have strong pressure machinery. Pressure can be created to discharge the seawater so that repairs can be carried out. Will not affect the ship's continued navigation.

   Therefore, it stands to reason that if there is a watertight compartment, the average ship will not sink.

  That’s why Qin Shiou opened two big holes for me, the Pirate, and the two watertight cabins were flooded together, so that would be enough for this ship to drink a pot.

  Civil ships generally have eight watertight cabins. As long as there are four watertight cabins that can be used normally, the ship will not sink, at most serious flooding.

So at first Robin and the sailors on the ship were panicked, but not desperate. They ran towards the cabin cursingly. After confirming the situation, Robin kicked the cabin door angrily and shouted, "Spencer, **** it," Where is you idiot? Hurry up, pull me the water pump pipe and get the water out!"

  The chief mate ran over in a panic, summoned the sailors to enter the cabin with the pumping pipes, and began to pump water out.

  Robin summoned the second officer and the captain to prepare to remedy the situation, and the three of them took the blueprints to start negotiations.

   But something was wrong. As they negotiated, the ship never stopped sinking, but was sinking slowly and unswervingly.

  It is reasonable to say that after one or two watertight compartments are flooded, as long as the waterproof door is closed in time, it will not sink. Because the one or two cabins on the ship are flooded at this time, the hull will enter the equilibrium stage after lowering a certain distance. After the water level in the cabin is level with the sea level, the water will not continue to enter according to the principle of air pressure.

  So, why is this ship still sinking?

  Robin was frightened and angry. At this time, the chief mate ran out with the sailors swarming. He grabbed the chief mate and shouted, "What's the matter? Damn it, why is the ship sinking?"

  The first officer exclaimed in horror: "Hurry up, Captain, the ship is sinking, we have to abandon it!"

   Upon hearing this, Robin lifted his foot up and kicked the unsteady first mate into a ground gourd. He roared angrily: "What nonsense, how can the damage of the two watertight cabins lead to the sinking of the ship?"

  The chief mate said with a sad face: "I don't know. Maybe the waves are too big. The water is swept in by the waves. It has already passed the waterproof partition and entered other cabins!"

These cabins of ships are not completely airtight. This is because of air pressure and material strength problems. Simply speaking, material strength problems are thermal expansion and contraction. If the cabins are completely sealed, high-strength materials are required, otherwise they will experience changes in heat and cold over time. , The cabin steel plate will be deformed.

Except for warships and some luxury cruise ships and important ships, most ships will not use airtight watertight cabins, including the 10,000-ton giant ship. There is a waterproof partition between the cabins and there is a gap above the partition, which can balance the air pressure. Coming is to give room for material deformation in the cabin.

  In this way, there is a hidden danger, that is, even if only one watertight compartment enters the water, the seawater will roll up and enter other watertight compartments through the space above the watertight partition.

  According to common sense, this kind of extreme situation will not occur. This is only theoretical. In fact, the probability of this kind of thing happening is too low. This kind of thing can only happen when it hits a rock in a storm.

  However, if it hits a rock in a storm, it will definitely be mortal, because the ship will continue to hit the rock if it is attacked by the waves and storms.

   Therefore, in reality, the watertight compartments of civilian ships will not be completely sealed. After all, civilian ships are not the same as warships. Warships are required to perform missions. Some missions are carried out in storms. Civilian ships will avoid entering the port when encountering a storm.

  In this way, I am the tragedy of Pirate...(To be continued.)
