Chapter 504 Construction of Ship No. 3

in the afternoon.

Yang Fan went back to Donghai Institute and sat in his office with a smile on his lips, thinking about the scene when he had lunch with Han Jiang in his mind.

That western restaurant is good. It is worthy of being a high-end restaurant. Although it is a bit more expensive, it is very authentic. Their steaks are also good.
Just thinking about this, the phone ringing on the desk interrupted Yang Fan's thoughts.

This is a phone call from Luo Jianguo from the capital. As soon as he connected, his familiar voice came from inside, "Comrade Yang Fan, I have received a call from Dongjiang Shipyard. At your suggestion, our No. 3 ship will The construction of the slipway will officially start on December 12.”

It can be heard that Luo Jianguo is in a good mood, and he is very satisfied with Yang Fan's suggestion.

As the commander-in-chief of Project 054, he certainly hopes that the construction of No. 3 and No. 4 ships will be completed sooner, and he even hopes that they will be put into naval service earlier.

Yang Fan smiled and said: "I see that the construction of the various sections of the No. 3 ship is progressing well, especially the middle section of the bottom of the ship has been completed. I made this suggestion, but I did not expect Dongjiang Shipyard to accept it without hesitation."

Luo Jianguo praised: "This proposal is good. I dream that it will start the construction of the berth sooner."

On the phone, the two chatted for ten minutes.

According to the current shipbuilding technology, especially according to the general construction method, the construction of the ship is divided into blueprint lofting, number material, and steel pretreatment, and then at the same time as segmental welding and large-scale segmental and general segment assembly. Outfitting processing, component assembly and welding, component forming processing, component edge processing, etc.

When he was at Dongjiang Shipyard this morning, Yang Fan learned from Sun Baoguo that in addition to the good progress in segmental processing, Dongjiang Shipyard is also making good progress in other parts such as outfitting processing, component assembly and welding, and component processing.

The conditions for the construction of the No. 3 berth are basically mature, so Yang Fan proposed to start the formal construction of the berth on December 12. Unexpectedly, this suggestion was not only adopted by Dongjiang Shipyard, but also made Luo Jianguo very happy .

The two chatted on the phone for ten minutes.

Not only did they talk about the No. 3 ship, which is about to start construction of the berth, but also the No. 2 ship, which is undergoing sailing trials.

This ship was built by Xiangjiang Shipyard. It was launched a few months ago, and a series of tests and verifications have been carried out. At present, many tests have been basically completed, and even the sailing test is coming to an end.

Luo Jianguo told Yang Fan that in about a month or so, the No. 1 ship should be commissioned into the navy before New Year's Day. At that time, a grand commissioning ceremony will be held at Xiangjiang Shipyard.

In addition to these, Luo Jianguo also inquired about the progress of the design of 054A with concern. After hearing Yang Fan's introduction to the design, he was very relieved.

The time given by the military is 10 months to complete the overall design of 054A. Now it seems that it will take less than 10 months, and Yang Fan's goal is 8 months.

end of June.

The No. 2 construction berth of Dongjiang Shipyard, which has been quiet for several months, has become lively again. This is a newly built horizontal construction berth. After the completion of the construction, it has been idle here and has always been relatively quiet.

No, it is not called idle, it is waiting for the No. 054 ship of the Type 3 guided missile frigate, and now, the preparations for the construction of the berth can finally start.

There are many workers here, as well as some technicians and managers.

A laser theodolite has been set up there, and two technicians are operating it, checking the level and vertical of the tire frame on the berth.

The construction method of the general section is further divided into the positive fabrication method and the reverse fabrication method. The 054 ship adopts the positive fabrication method, that is, the position of the segmented construction is the same as that on the real ship.

Its advantage is that the construction conditions are good, and the molding line is easy to guarantee; the disadvantage is that the tire frame is complicated and the workload of the curve is large.Generally speaking, the advantages outweigh the disadvantages, especially for ships like the 054 ship, it is more appropriate to use the positive method.

Some tire racks have been placed on this horizontal construction slipway, and with the help of laser theodolite, technicians and workers are fine-tuning the position.

There are also some segmental components that have arrived at the construction site, and the production atmosphere is very strong, and every worker and technician is full of enthusiasm.

1997 12 Month 1 Day.

It was a cloudy day and the weather was relatively cold. Almost everyone put on sweaters and thick coats, and a few even put on fashionable down jackets.

No matter how cold the weather is, it can't stop everyone's enthusiasm. Early in the morning, there are many people who build the slipway, and everyone starts to get busy early.

Yang Fan arrived at Dongjiang Shipyard.

Even though he was busy, and the No. 3 ship began to build the berth, Yang Fan still wanted to come and have a look. He saw the placement of its first section with his own eyes, and wanted to see the butt joint and welding of each section with his own eyes.

After opening the car door and getting out of the car, Yang Fan thought to himself, the weather today is really a bit cold, at least a few degrees lower than the previous few days, the weather forecast said that the Siberian cold current is going south, and there may be rain and snow in a few days Appear.

Not far away is the No. 2 construction berth of Dongjiang Shipyard. Yang Fan has already seen a lot of people there, and it seems that Sun Baoguo is there, so he walked over there.

Sure enough, it was Sun Baoguo, who arrived at the berth early.

He also saw Yang Fan coming over, and immediately came over enthusiastically, shaking hands tightly, "Master Yang, I came here so early, it's not yet 08:30."

Yang Fan smiled slightly, "After leaving the house, I drove here without even going to the East China Sea Institute, just to see the construction of our No. 3 ship with my own eyes."

Sun Baoguo said: "Hurry up, our preparations are almost done, and the middle section of our ship's bottom will also be transported."

The two chatted about the construction of the No. 3 ship.

About ten minutes later, there was a commotion, and someone shouted loudly: "Our first segment is here, look!"

Many people followed what he pointed and saw the first section that was brought over. This is the middle section of the bottom of the ship, and it is also the base section for the construction of the entire ship platform. During the entire construction process, It is the build basis.

It was transported to the designated location next to the slipway.

A manager walked over quickly and asked for instructions loudly: "Mr. Sun, the middle section of the bottom of the ship is in place, and we can start hoisting."

Without hesitation, Sun Baoguo waved his hand and said, "Lift the hoist immediately."

The construction slipway has a supporting large crane, which can lift sections of two or three hundred tons, and of course the mid-bottom section of more than 100 tons is not a problem.

The workers began to operate, hung up the hook, and someone commanded the hoisting. The section was slowly hoisted, and then carefully and slowly placed on the designated position of the horizontal construction berth.

A pink line has been drawn at that position. After the middle part of the bottom of the ship was hoisted to this position, it slowly fell, and the whole scene became quiet.

Yang Fan looked at this section, watching it slowly fall.

Experienced workers in Dongjiang Shipyard know that it is more difficult to place the middle section of the bottom of the ship as a benchmark, and its technical requirements are very high, whether it is horizontality or verticality.

Some people even remember that when the first ship of the 054 ship started the construction of the berth, the middle section of the bottom of the ship, which was exactly the same as this one, had to be hoisted several times and fine-tuned several times before it was finally qualified.

It falls slowly.

Finally, it landed firmly on the designated position of the berth, completely within the powder line, and inspectors and technicians immediately inspected it.

The other workers also stopped, all looking at this section.

Some people said in their hearts that it is almost impossible to lift it once, and it is estimated that it will take several repetitions. It is very good if it succeeds this morning.

"The first segment has landed firmly on the slipway."

"I think it will be hoisted again soon, and it is estimated that it will be hoisted several times."

"I still remember when the first ship of the 054 ship was built. It was hoisted several times and fine-tuned before finally meeting the technical requirements."

"Thanks to the laser theodolite that time, otherwise, it would have been a lot of trouble."

"."

Many people were discussing in this way, looking at the middle section of the bottom of the ship that fell steadily on the slipway, those with good eyesight found that it seemed to fall within the pink line, which was not bad at all.

More people were very surprised that the re-lifting they imagined did not happen.

This is not right!

Don't you need to lift it again?
Many workers are at a loss.

It will be delivered in the third shift, and I ask you for a few monthly tickets and recommendation tickets for support. Thank you in advance.
