Brothers and sisters, if you have a vote, vote for it, and thank you here! ****

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

"Shet, these bastards are crazy! Damn, there are too many of them, guys shouting, damn it, you must kill these bastards! ”

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

"Don't call the police, stupid, Big Brother Robin's boat also has water cannons, and most importantly, although they fired, didn't you shoot? And we also have large-caliber rifles on board! ”

"Don't talk, be careful, there are a lot of reefs in the sea we are entering now, be careful not to run aground!"

"It's okay, I've walked through here, the reef isn't dangerous, do those bitches still think this is the Bermuda Triangle? Ha, how can our ship hit the reef with such a small draft......"

"Boom!" A muffled sound!

"Fack! Fack! Fack! Robin's panicked roar was immediately heard over the radio.

The group of hunters was stunned, and someone shouted, "Brother Robin, what's going on?" ”

Where is Robin still in the mood to answer? He was planning where to summon his brothers to take revenge just now, and this time he was really embarrassed, and now he still feels that his skin is hot and painful, and his image is even more embarrassed.

All of a sudden, I was the Pirate as if I had suddenly hit something, or was hit by something, and the hull shook violently, and then several red lights came on in the cockpit, and the beeps continued to sound.

"Woooooooooooo

The beep beeped and the ship vibrated continuously.

Qin Shiou took control of the giant demon. When he waited for me to pass above a hideous reef, the lurking troll first chiseled a gap in the bottom of the ship with a mace, and then used the Beacon Mace skill to bombard the gap one after another, quickly expanding it into a hole the size of a basin.

More than that, he also controls the troll to wander forward. A large hole was made in the front of the ship, which was even larger than the previous one, creating a scene where the bottom of the ship hit the reef and then hit the reef in front of it.

The turbulent sea rolled and roared into the hull, seeing this, Qin Shiou smiled slightly, and gave the order to the giant demon to let it leave, that's it, deep hidden merit and fame!

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

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

The so-called watertight compartment, as the name suggests, is to use bulkhead plates to divide the cabin into compartments that are not connected to each other. Such. Because the cabins are tightly separated from each other, it is in the middle of the voyage. Even if one or two compartments are broken and water enters, the water will not flow to the other compartments.

From the point of view of the ship as a whole, as long as it maintains considerable buoyancy, the ship will not sink. And there is a buffer of a watertight cabin, even if the damage is great, even if there is too much water to support the ship. There was also time to reduce the deadweight by abandoning the cargo, and to support the ship to continue its normal voyage.

Modern steamships are more technological, and a watertight compartment is flooded as long as the ship does not sink, because these cabins have high-pressure machinery that can create pressure to expel seawater. This allows for patching without affecting the ship's continued sailing.

Therefore, it stands to reason that if there are watertight compartments, the ship will not sink.

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

Civil ships generally have eight watertight cabins, and as long as four watertight cabins can be used normally, the ship will not sink, and at most it will be seriously flooded.

So at first, Robin and the sailors on the ship were panicked, but they were not desperate, they scolded and ran towards the cabin, and after determining the situation, Robin angrily kicked the hatch and shouted: "Spencer, damn it, where are you idiot?" Hurry up, pull the pump pipe over to me, pump the water out! ”

The first mate ran over in a panic and summoned the sailors to carry the pumping pipes into the cabin and start pumping water out.

Robin summoned the second officer and the wheel chief to prepare for the remedy, and the three of them took the drawings and began to negotiate.

But something was wrong, and while they were negotiating, the ship had not stopped sinking, but was slowly and unswervingly sinking.

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

So why is the ship still sinking?

Robin was furious, and at this time, the first mate ran out with a swarm of sailors, and he grabbed the first mate and yelled, "What's the matter? Damn, why is the ship still sinking? ”

The first mate shouted in horror: "Hurry up, captain, the ship is sinking, and we must abandon ship!" ”

As soon as he heard this, Robin raised his foot and kicked the first mate who was not standing firmly on the ground and kicked the gourd, and he roared angrily: "What nonsense, how can the damage of the two watertight cabins lead to the sinking of the ship?" ”

The first mate said with a sad face: "I don't know, maybe the waves are too big, and the water is rolling in with the waves, and it has already exceeded the waterproof partition and entered other cabins!" ”

These compartments of the ship are not completely sealed, this is because of the air pressure and material strength problems, simply put, the material strength problem, that is, thermal expansion and cold contraction, if the cabin is completely sealed, it must be high-strength materials, otherwise the cabin steel plate will be deformed after a long time of cold and hot changes.

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

There is a hidden danger that even if only one watertight compartment enters the water, the sea water will tumble up and enter the other watertight compartments through the space above the watertight partition.

According to common sense, such an extreme situation will not occur, this is only theoretical, in practice the probability of such a thing happening is too low, and such a thing will only happen if it hits the reef in a storm.

However, if the ship hits the reef during the storm, it will definitely die, because the ship will continue to hit the reef when it is attacked by the waves and storms, and even if the watertight compartment is fully enclosed, it will all be damaged and sink into the water.

Therefore, in reality, the watertight compartment of a civilian ship will not be completely sealed, after all, a civilian ship is not the same as a warship. Warships are on a mission, and some of them are carried out in storms, and civilian ships will take refuge in ports when they encounter storms.

That's it, I'm the Pirate tragedy...... (To be continued.) )
