The newly built liquefied gas ship was tested by the cold for the first time.

Of course, the experiment is carried out step by step, and it is impossible to add LNG as soon as it starts. If it leaks directly, there will be nothing you can do to save it.

First, you need to use dry nitrogen to purge the filling pipeline and the liquid cargo fence system to blow out the air and moisture inside for the purpose of drying and reducing waste. After all, if you are filling directly, the air in the

Both oxygen and moisture can have dire consequences.

If the oxygen in the air comes into contact with natural gas, it may reach its limit and cause an explosion. If it comes into contact with water vapor, the water vapor may be instantly frozen into ice spikes. During the process of filling liquefied natural gas, it may be blown by the air flow.

The impact caused the ice spikes to puncture the liquid cargo fence system and leak out. This would cause serious trouble.

After the nitrogen is purged, the next step is to use low-temperature liquid nitrogen to pre-cool the pipeline and liquid cargo fence system, and check whether the liquid cargo fence system is qualified.

Although direct filling of LNG can have the same effect, if the liquid cargo fence system leaks, something big will happen. Even if liquid nitrogen leaks, this thing will not burn or explode, so it is safer.

.

Therefore, it is safer to use liquid nitrogen for pre-cooling first. The first SCA liquefied gas ship they built had problems at this time.

After filling the liquid nitrogen, everything was normal, but after waiting for ten minutes, the sensor detected a leak in the liquid cargo fence system! This shocked everyone. They quickly checked and found that there was a leak in the liquid cargo fence system.

Cracks in manganese steel.

Zheng Yishan left the naval officer in the office and rushed to the dock with Cui Taegen.

The liquefied gas filling truck has left. After all, there is a crack. The next step of filling the liquefied natural gas will be impossible. The liquid nitrogen truck has also left. The liquid nitrogen filling has ended. The dock is empty. Look.

It seemed that everything was going well, but looking at those people with sad faces, there was no intention of celebrating.

Wait, there is another person.

Shipowner representative Azar.

In the field of civilian ship construction, the shipowner's representative is a very common system. He is responsible for the quality control of the entire ship. Without his signature, not a single steel plate can be moved. At the same time, he is also responsible for all aspects of the entire ship from beginning to end.

Build and test the project and never leave.

Of course, he was also present for this important pre-cooling work. Among the mournful Southern Kimchi people, Azar's expression was much calmer.

"Mr. Zheng, is your liquid cargo fence mature? How could such a major change occur?"

"I'm sorry, this was our negligence. Please rest assured that the liquid cargo fence system we built is very reliable. This time it was just an accident, a small accident."

"Then what to do next?"

"We will definitely repair the crack." Zheng Yishan said: "We will also strengthen the liquid cargo fence system to ensure that this kind of thing will not happen again."

"Repair?" Azar's tone was cold: "As the shipowner's representative, I reject this irresponsible repair method. After such repairs, the integrity of the cargo fence system cannot be guaranteed."

Zheng Yishan had an ominous premonition in his heart: "What do you mean?"

"I request that this liquid cargo fence system be replaced to completely prevent similar problems from happening!"

replace!

For a liquefied gas ship, the most important thing is the cargo fence system. If it is made of Yinwa steel, it can account for more than 60% of the cost of the entire ship. Even this kind of high manganese steel is not very cheap.

If you build a new one, there will be no profit from this ship.

What's more important is the construction period. If you build a new one, will the construction period be enough? If the delivery date is delayed, according to the contract, you will have to pay three times the compensation.

Wait, is the other party just waiting for triple compensation?

In the global shipbuilding industry, this kind of thing also happens. Shipowners will deliberately delay in order to abandon the ship or ask for compensation. When the Oriental shipbuilding industry went international, many people were deceived like this. But they are picky.

Guo Ke is an important member of the West, and they are also very cautious in doing business.

"Mr. Azar, if we build a new liquid cargo fence system, it will take longer and may delay the delivery time. If it causes a delay, it is not our responsibility."

"Why isn't it your responsibility? The ships you built have quality problems, and we require them to be replaced with brand new ones. Is it wrong?" Azar said: "It is clearly written in the contract. If you refuse, then

My shipowner will not take over this ship, we will go to London to litigate!"

If it really comes to this, then the reputation of the South Korean shipbuilding industry will be ruined, and I am afraid that we will never receive another LNG ship in the future!

Zheng Yishan gritted his teeth: "Okay, then we will change!"

Change?

All the Kimchi people are very nervous. Will it be in time? Can they catch up?

After leaving, his subordinates asked anxiously: "Mr. Zheng, we are too late!"

"Install the liquid cargo fence system built for the No. 2 ship!" Zheng Yishan said: "Strictly control the quality, reinforce it when it is necessary, and never cause problems again!"
