The Pluto is just a refrigerated ship with a full load displacement of 4,900 tons.

This type of ship is almost the smallest in the Lu family's shipping fleet. Other ship types are 10,000 tons, 20,000 tons, 30,000 tons, 50,000 tons and even 80,000 tons.

The largest refrigerated ship owned by the Lu family, with a full load displacement of 83,200 tons, can be said to be a veritable giant.

Due to the large amount of electricity required by refrigerated ships, engines are often overinstalled.

For example, this refrigerated ship with a displacement of 4,900 tons is equipped with four diesel engines. The total power output reaches 30,000 horsepower.

Purely in terms of power, there is no problem. Enough is enough.

What Lu Lingqi asked for was to reduce costs.

She was ready to replace the four Panshi 500 diesel engines.

According to the data given by Cao Zhiyuan, each diesel engine consumes 50 liters of fuel per hour, and the fuel consumption of four diesel engines per hour is only 200 liters. Costs can be significantly reduced.

The cost of 200 liters of diesel is more than 1,000 yuan. This already includes the entire fuel consumption.

If it is a simple electricity consumption, it is only 700 yuan per hour.

"Now, our diesel fuel consumption has been reduced again. Only 20 liters per hour. Wang Buan said slowly.

"That's even better. Lu Lingqi said happily, "Our shipping costs can be reduced again." ”

"Miss Lu. Wang Bu'an pondered and said, "Do you often go to the ocean?"

"Almost once a month. Lu Lingqi replied casually.

"Then you must have a lot of experience sailing at sea?"

"So to speak. ”

"Good. I introduce a friend to you. She's my friend. She also wanted to go to sea. It's just distant-water fishing. ”

"That might be dangerous. ”

Lu Lingqi shook her head. She is not interested in marine fishing. It always feels too dirty, too dangerous.

In calm seas, there are no fishery resources. A large number of fishing boats are piled up, and even if there were, they would have been caught a long time ago.

Only those more dangerous and relatively harsh sea areas have abundant seafood.

The problem is, not everyone can get in.

The Lu family's shipping fleet, every time they sail, will try to avoid dangerous sea areas.

She's not going to do risky things.

However, if Han Xuewei wants to develop, she has to take risks.

The Bering Sea, Antarctica, the Southern Indian Ocean, the South Pacific and other places are relatively rich in fishery resources. The problem is that the climate in these places is also very harsh.

24 hours a day is stormy, not to mention the icy Bering Sea. The South Pacific Ocean alone seems to be a calm patch. However, when the storm appears, if the fishing boat can't dodge, it will go directly to see the Sea Dragon King. The number of fishing vessels that are swallowed up in the South Pacific every year is still very significant.

And some of the so-called forbidden areas, until now, no fishing boat dared to approach them.

For example, the Paleni Islands near Antarctica are off-limits to fishing boats.

All the fishing boats that tried to enter the area had disappeared without a trace.

Even expedition ships, research ships, exploration ships, etc., are easily afraid to approach the Paleni Islands for fear of accidents.

The waters around Heard Island in the southern Indian Ocean are also very dangerous. Not only do there be inexplicable wind and waves from time to time, but also a large pile of ice floes suddenly pop up from time to time. If you are not careful, the ship will be destroyed and people will die. Over time, there was no need, there were simply no ships approaching these places.

"If she must go, what advice do you have?" said Wang Buan.

"I have three suggestions. Lu Lingqi was blunt.

"Speak. ”

"First, at least a giant ship of more than 10,000 tons. A ship that is too small will not withstand the storm. More than 20,000 tons is better. It is better to equip a helicopter. ”

"And then?"

"Second, at least three ships of operation. It would be nice to have an auxiliary medical ship. It is required that the displacement of each ship is more than 10,000 tons. ”

"And then?"

"Thirdly, the hull is built in the class of an icebreaker, equipped with sufficient power. ”

"Good. ”

Wang Buan nodded with satisfaction.

Very simple advice. But very practical. Especially the last point is very important.

Many people actually ignore the last one.

The biggest feature of icebreakers is that they have a very strong ability to escape from danger.

In rough sea conditions, the most basic requirement is the ability to protect oneself. The self-protection of icebreakers is the strongest.

Negotiate and sign the contract.

The total cost of this renovation is 20 million yuan.

The new Hongyang Shipyard is responsible for providing four Panshi 500 diesel engines, as well as a gearbox, transmission spindle, thruster and propeller.

Miss Lu actually heard about the tuna on the way and decided to replace the propeller.

The original refrigerated ship had an economic speed of only about 15 knots. The maximum speed is about 20 knots.

At such a speed, the most feared thing is pirates.

The speed of the pirate ship is extremely fast. They tend to be above 25 knots. Some even exceed 30 knots.

In the Gulf of Aden, the speedboats of Somali pirates are even capable of exceeding 40 knots. When merchant ships encounter them, there is absolutely no chance of evasion.

Lu Lingqi hopes to increase the speed of the Pluto freezer ship to more than 40 knots.

At this speed, you can basically get rid of pirates.

Even if it is impossible to get rid of it, such a high speed is enough to prevent pirates from boarding the ship.

Generally speaking, as long as the speed of the ship exceeds 30 knots, there is no way for outsiders to force boarding. Helicopters or anything won't work.

The bridges seen in TV movies where helicopters forcibly land merchant ships are all based on the slow sailing speed of merchant ships. The speed of those merchant ships usually does not exceed 15 knots. If it is more than 30 knots, the helicopter simply does not have a chance to find a landing site. Once it gets close, it will collide and destroy the plane and kill people.

"Chief Engineer Wang, how many days will it take?" Lu Lingqi said.

"If you don't replace the refrigeration equipment, it will only take five days. Wang Buan replied.

"What does Chief Engineer Wang mean, is it possible to replace the refrigeration equipment for free?"

"If Miss Lu needs it, you can. ”

"Really?"

"Really. ”

Wang Buan said affirmatively.

Why so generous?

The main reason is that Wang Bu'an found that the refrigeration equipment of the Pluto is actually a bit old.

It adopts a central refrigeration method, relying on five large cold shrinking machines for air cold and heat exchange.

He wanted to replace all five compressors.

It's obsessive-compulsive disorder again!

When I see something unpleasant, I can't help but change it.

Does the compressor have a technical content?

Of course not.

It only needs to be roughly copied and the details modified.

The fundamental measure is the use of new materials. In this way, the cooling effect is better and the energy consumption is reduced.

The point is, its lifespan will increase dramatically.

It just so happened that these five compressors were already out of their shelf life.

"Chief Engineer Wang, how long is the warranty of your compressor?" asked Lu Lingqi with interest.

"Ten years. Wang Buan replied without thinking.

Is there a problem?

Of course there is no problem.

The compressor he made has a lifespan of more than ten years.

If there is no terrifying external impact, it will not be a problem to use it normally and persist for thirty years. That's basically the life of a refrigerated ship.

"Do you need to extend the time for the retrofit?"

"No, you don't. ”

"Good. ”

Wang Bu'an instructed Mihara Takeshi to start work.

The first thing to do is to disassemble all the original power systems.

New power system, remotely controlled production.

At the same time, there are also compressors.

In order to avoid modifying the line, Wang Buan copied five compressors that were basically identical.

Lu Lingqi didn't leave.

She actually wanted to witness the whole transformation process.

Hearing is false, seeing is believing.

For such an important matter, she must be present in person.

If the Rock 500 is really so magical, the Lu family's fleet will line up to come for transformation in the future.

However, the new Hongyang shipyard seems too small?

10,000-ton ships can't get in at all.

"Chief Engineer Wang, do you have any other large docks?" asked Lu Lingqi worriedly.

"Not yet. Wang Buan shook his head, "However, there will be in the future." ”

"But there's no room for expansion!"

"yes!"

This is also what Wang Buan needs to consider.

Around the new Hongyang shipyard, there is indeed no suitable place to expand the dock.

If you want to receive more converted ships, you have to find a way to buy them, or build a larger dockyard.

With the current situation, it is better to build a 500,000-ton dock in one step.

What if there really is a 100,000-ton giant ship that needs to be remodeled?

That's a possibility.

Of course, there is no rush to this question for the time being.

I can't rush it.

It's best to let Cheng Kailong help solve it.

Cheng Kailong has the most information. Which large shipyard needs to be sold, he knows for sure.

Wang Buan was concentrating on supervising the work when he suddenly heard someone calling him.

It was Han Xuewei who came.

At the same time, Pang Xihua and several other people arrived.

Among them was a young man, in his twenties, with a straight and straight figure, and at a glance he knew that he was not an ordinary person. He was carrying a large suitcase.

There is also an old man. It looks a bit like Albert Einstein. The beard is also thick and white.

Wang Bu'an waved his hand at them, indicating that he would wait.

"Pang Xihua?" Lu Lingqi recognized.

"Do you know the others?" said Wang Bu'an casually.

"That old man's name is Sheng Huainan. ”

"What else?"

"I'm sorry, I don't know anyone else. ”

"Thank you. ”

Wang Bu'an explained a few words before getting off the boat.

The faces of Pang Xihua, Sheng Huainan and others were very strange. It feels like you're looking at a monster. Everything around them felt familiar and unfamiliar.

The boat types are very familiar. But many aspects have been changed beyond recognition.

Especially the propellers. Not at all according to the standards.

Such a rough renovation can only be done by such a private shipyard.

I don't know how they passed the quality inspection?

Can you do whatever you want if you have technology?

Today's fourth update.
