One Thousand Five Hundred and Twenty-Eight Know Ourselves and the Enemy

So you say which shipper will choose to help him build the ship?

So at this time, not to mention the gap with the French GTT company, that is, compared with the three major shipbuilding companies in the Southern Dynasties, the gap between us is all-round.

The company that has been given high hopes has been chasing after more than ten years, but the gap is getting bigger and bigger...

If this is the company of his main competitor, it will definitely be criticized long ago, making you disgraced, and you will be detained as incompetent FB, overstaffed, and so on.

But for the H shipyard, they are not allowed to report or say anything anyway.

Besides, it's not that people are ashamed and brave, and they continue to chase after them!

When Xiao Feng planned to enter this field, he also probably understood the difficulty of shipbuilding, especially LNG shipbuilding.

And after understanding the difficulty, I also know that it is not entirely their fault.

If you want to blame it, you can only blame it for the all-round backwardness of our domestic industrial system.

From material science, to finishing, and then to design concepts, it can be said that it is this all-round backwardness that will make us widen the gap between us in the field of LNG ships and the Southern Dynasties.

You can say that building LNG ships is a complex large-scale system engineering.

The first is the basic technology, which mainly includes: the application of computational fluid dynamics technology on LNG ships, propeller design technology, sloshing pressure of cargo tanks, temperature field distribution of LNG ship hull, localization of LNG ship materials and equipment, and temperature stress of special piping systems of LNG ships analysis, research, etc.

We can say that these technologies are comprehensive and accurate at the beginning. Fortunately, HD shipbuilding has been doing shipbuilding for more than ten years, and finally made up some of the gaps in these theoretical aspects.

The second is design technology, which mainly includes: LNG ship design specifications and standards, hull demonstration, stress response of hull structure to temperature field of cargo tanks, analysis of hull buckling yield fatigue strength and deformation, typical power plant design technology, ultra-large capacity power station Power grid, integrated automation system, painting specification, etc.

In this regard, because we have the foundation of building large ships in the past, the gap is not big.

It is also the aspect with the smallest technological gap between us and the Southern Dynasties, and it is also the easiest to catch up.

The third is construction technology, which mainly includes: super-large segmented precision construction technology, general group and dock assembly technology, hull welding technology, new power plant installation and experimental technology, insulation box manufacturing technology and production capacity, pump tower manufacturing and Installation technology, in tile installation technology, in tile welding technical specification, cargo hold containment system tightness test technology, etc.

When it comes to this aspect, we are too far away from the Southern Dynasties, and it can even be said that we have gone to my grandmother's house.

Because it involves a lot of system engineering process design.

You, for example, later spent money on HD and introduced the Mark II LNG carrier design from GTT.

The concept of Mark I type is to use a layer of invar steel to make the inner lining of the storage bin, and then lay an insulating box of expanded perlite on the outside to ensure the isolation of the bin body and the hull.

After all, this warehouse is a warehouse of minus 163 degrees. If it is in direct contact with the hull, it will definitely freeze all the steel plates of the hull.

And the idea of ​​Mark II,

It is to lay two layers of this design to better prevent natural gas leakage and ensure the safety of the transport hull.

This will ensure that the carrier becomes larger and can transport more LNG at one time.

You must know that the first hull we introduced can only be built at a maximum of 100,000 square meters.

Using the hull of the Mark II, it is possible to build a large LNG carrier with a maximum of 170,000 or even 180,000 cubic meters.

And now the French have launched the Mark III technology. If this technology is used, it can build a maximum of 200,000 to 300,000 tons of LNG ships.

And this kind of ship, naturally, the larger the profit, the higher the profit, because the transportation cost will be lower.

And the reason why the insulation layer is made more, there is another important problem, that is, you have to ensure the evaporation rate of the liquefied gas during transportation.

It should be known that the Mark II hull is used, because the thermal insulation effect is better, and the evaporation rate can be kept very low during transportation, which greatly reduces the cost of the cargo owner.

And here is the process of laying these insulation boxes. For a 170,000-square-meter LNG ship, you need to lay more than 1,100 different types of insulation boxes, more than 55,000, and the accuracy of installation and splicing. You want to be within 0.5mm.

In this regard, the gap between us and the three major shipyards in the Southern Dynasties can be said to be comprehensive.

This is why, people can complete the construction of a 170,000-square-meter LNG ship within 600 days.

The main reason for our need for a 950-day construction cycle is that our HD shipyard, in addition to the support of domestic petrochemical transportation companies, is really not very competitive internationally compared with the three major shipyards in the Southern Dynasties.

As far as this construction cycle is concerned, we have to use one more year than others, and this alone will lose miserably.

Moreover, people introduced the technology of the Mark II LNG ship relatively early, and they have eaten it very well. On the basis of this technology, they have also developed their own technical system.

If nothing else, let's talk about the evaporation rate.

This is one of the most important criteria to judge whether an LNG ship is superior enough, because the more LNG you evaporate in transit, the greater the loss to the shipper.

So naturally the lower the evaporation rate, the better the performance of the boat.

The annual evaporation rate of LNG ships in the Southern Dynasties can be 0.7%, but we can only achieve 1%.

With this alone, people can save 4.5 million profit for the cargo owners every year compared to us in terms of LNG arrival rate.

So just to this point, how can you compete against others?

This is still the case when people have not come up with a unique FRS, a complete reliquefaction system.

If the cargo owner is willing to add a sum of money, then they can install a set of their own FRS system on the LNG ship, so that the annual evaporation rate can be reduced to 0.017%, which is almost equivalent to 100% degree of restoration.

LNG ships using this technology can save the shipowners profits every year, which is 9 million US dollars...

Just rushing into this technology, people have already dumped us as a position...

Then let’s talk about the shipbuilding technology. If nothing else, let’s talk about invar steel. You must know that the place where invar steel is used on LNG ships is definitely only the warehouse.

There are also pipelines for transporting LNG, various control valves, etc. If ordinary steel is used, it will definitely not be able to withstand LNG at minus 163 degrees, so it is necessary to use invar steel parts for this kind of parts.

This not only involves the production of invar, but also the processing and welding of invar.

In this respect, the Southern Dynasties countries have truly understood the French's technology. First of all, they can produce invar steel by themselves.

Secondly, in this construction system, people are leading in all directions.

For example, in their country, there are enterprises specializing in the production of invar welding machines, as well as invar pipes, and invar valves.

Even all kinds of invar steel parts can be produced by the whole series.

As long as your shipyard needs it, supporting companies like me can immediately come to help.

You make a request, and I can come up with a finished solution for you in a few days.

To build a LNG ship, 400 invar steel pipes and invar trihedrons are needed, and more than 60,000 small invar steel parts are needed. These people can produce all of them by themselves.

And on our side, 90% needs to be imported... This is to say less...

This is also the main reason why others only need 600 days for LNG, but we need 950 days.

Not much else to say, let's say that the cargo warehouse on a 140,000-square-meter LNG ship is 130 kilometers long just for the welded seams.

In these respects, people in the Southern Dynasties have long used automatic welding machines.

Because if manual welding is used, it is not only costly, but also prone to mistakes.

If this welding has another leak point, it will require at least 1000 hours of rework...

So in order to improve productivity, they have specially developed their own automatic welding equipment.

And this kind of equipment is currently the only copy of Scorpion Baba in the Southern Dynasty. Our HD company has to import it from them.

So this gap... let's despair!

If you want to build several LNG ships to supply our domestic petrochemical companies, import LNG from the Middle East for use.

The Southern Dynasties country is not stingy, exporting some invar steel parts or processing tools to us.

But if you say you want to think internationally, go grab an order with them, hehe.

As soon as someone reaches out their hand, they can kill you, and this is still without a price war with you.

Just relying on technology to crush, people can crush us.

So whenever Xiao Feng sees on the Internet recently that there are many people worrying about the people of the Southern Dynasties living in the shadow of monopoly chaebols and unable to eat fruit and beef, he finds it funny.

The cars of the Southern Dynasties are about to be crushed by domestic cars, and the mobile phones of the Southern Dynasties are the most rubbish, not as good as our domestic machines.

Whenever he heard this kind of argument, Xiao Feng felt seriously speechless.

I really don't know who gave these guys such courage.

Why! Is it so difficult to face the gap and admit the gap?

What is the difference between doing this and those ostriches who cannot face history and smear Yuanqing every day...

After all, only when you face the gap and admit the gap can you know yourself and the enemy, and then you can catch up with others if you know shame and then be brave.

Even if it takes a long time to catch up, as long as you work in the right direction, you will see results sooner or later.

But every day such self-proclaimed hi, what good can it do?

Don't say every day that Japan, which has been lost for 30 years, is the country of the Southern Dynasties. In fact, not only in the field of electronics, but also in the field of machinery, there are many others who are ahead of us...

This time, Xiao Feng and Qin Xiaotian proposed that if they want to jointly build LNG ships, they want to launch a pursuit of enterprises in the Southern Dynasties from this large-scale systems engineering field.

And through a period of time before, he has obtained the FRS technology that the shipbuilding enterprises of the Southern Dynasty are most proud of through the Li Jiushi in the Southern Dynasty...
