Zhao Jingfu and Feng Chen watched Liu Gong carefully checking every noise situation in the room, but his actions seemed a bit funny. He held the instrument in the air and quietly observed the data on it. The assistant on the side was
The logbook records the decibels of noise in the room.
Suddenly, Liu Gong looked at the instrument in his hand and was stunned for a moment, then put the instrument back to the distance and tested it again.
"48 decibels is beyond the standard!"
The assistant was stunned for a moment after hearing this data. Then he turned his head and took a look. The instrument indeed showed 48 decibels. According to the relevant environmental protection data standards, the noise in the room cannot exceed 45 decibels. This room is unqualified!
"Liu Gong, what's wrong?" Feng Chen vaguely heard the conversation between the two.
"The noise has exceeded the standard. I have to call the engineer in charge to take a look at the situation!" Liu Gong shook his head slightly, "I don't know what caused it. I'll go to other rooms to check!"
Immediately, Liu Gong and his assistant went to several rooms next door. According to the data of the acoustic detector, only this room had a problem that exceeded the standard. It seemed that it was not caused by the external environment.
"What should we do in this situation?" Zhao Jingfu asked Feng Chenyi in a low voice.
No one wants this situation to happen. After all, it is easy to build something, but if there is a problem and it needs to be modified, the time and energy required will be much greater than the construction. It is the same as welding components. Welding is not easy.
However, if welding errors occur and changes are made, the losses will be even greater.
Unexpectedly, Feng Chenyi smiled faintly: "It's no big deal. There are no problems in other rooms. It must not be a matter of material or structure. It should be that the sound insulation in this room is not done well. They will wait for a while
Check it carefully again to determine the final source of noise, and then solve it based on this. This situation is not common but it is not difficult!"
What Feng Chen said was not a difficult thing, but Liu Gong and others saw it as very difficult. There are many causes of noise, and they come from all directions. It is not easy to determine the specific location of the noise.
.
Liu Gong and his assistant wandered around the room for more than half an hour, and finally determined that the source of the noise in this room came from the ceiling. Now that the entire room had been decorated, he naturally could not dismantle it for inspection without permission, so he had to look outside the door.
Feng Chen, who was standing, called for help.
"Feng Gong, look at the noise signal here. Is there a pipe coming from here?" Liu Gong pointed out the acoustic detector to Feng Chen.
Feng Chen hurried back to his room, took out his laptop, and looked up the pipe diagram of the room. After searching for a long time, he still couldn't find any pipes that had any serious impact.
"Could it be the air-conditioning pipe?" Seeing the group of people working so anxiously, Zhao Jingfu on the side suddenly said.
"Air conditioning pipeline?" Liu Gong seemed to realize something, "It's really possible!"
Feng Chen immediately looked up the air-conditioning pipeline design diagram, and sure enough he found that there was a main air-conditioning pipe passing through the corner of the room. The excessive noise just now was probably the vibration noise from the air-conditioning system.
"It seems that we need to call in the water and electricity engineer and take another look!" Liu Gong immediately recorded the entire inspection process in the inspection record book. Of course, he did not say that this was the result proposed by Feng Chenyi and Zhao Jingfu.
Seeing Liu Gong leaving, Zhao Jingfu couldn't help but admire: "The engineer has been running back and forth several times because of the 3 decibel noise that occasionally exceeds the standard in this room!"
"It's not over yet. It won't be truly over until the noise source is completely eliminated and the entire noise test is passed." Feng Chen sighed and said, "That's what I'm doing now. I must take all possible situations into account."
All problems are nipped in the bud, leaving no hidden dangers behind!”
Zhao Jingfu also knows that this rule not only applies to these equipment engineers, but also applies to them. All welded projects need to go through several rounds of inspections before they can sign the confirmation form. It is even stricter than at Fengyang Shipyard, and
Now that they are on the Blue Whale, they still need to abide by various very strict regulations to prevent any accidents.
There have been cases like this before, but it was not at Fuhai Group. During welding work on a newly built ship, a bit of welding slag inadvertently fell into the rope, which eventually caused a big fire. Although it did not
It caused casualties, but the damage to the hull was not small.
The various pipelines of the Blue Whale are now being debugged. Although various preventive measures are in place, prevention is always better than remediation afterwards.
After chatting with Feng Chenyi, Zhao Jingfu returned to the work area where his team was located. This was the bottom platform of the Blue Whale, and further down were the columns and pontoons.
Since the columns were welded by himself, he was relatively familiar with this place. However, the welding team mobilized by the headquarters was not only Zhao Jingfu's team, but also welder teams from other shipyards. All teams were organized into three shifts to ensure welding.
The task will not be interrupted.
Many welders are still very curious about the powerful performance of f690. From time to time, they come to Zhao Jingfu to ask questions in this regard. They know that once such high-strength marine steel can be produced in China, this kind of marine steel will be used from now on.
The number of applications will gradually increase. Being able to gain early insight into the welding skills of this ultra-high-strength offshore steel will be of great help to future work.
Zhao Jingfu did not hold anything back. He told everyone his experience in welding high-strength marine boards and various precautions in detail. He even opened a small training class for these people. Even though everyone
If you don't have the ability to successfully complete a difficult welding task like f690 like Zhao Jingfu, you can at least understand the whole process so that you won't be unable to start when the time comes.
Zhao Jingfu's welding task went very smoothly. After all, he had experience in welding F690 before, so he was no problem with the tasks on the platform. With everyone's concerted efforts, all the welding tasks at the closed joints of the Blue Whale were completed, and the Blue Whale was already
Integrated into one, standing on the dock, waiting for the arrival of the most important test.
Zhang Yujie is also in the headquarters reading the daily inspection reports submitted every day, thinking about when he can complete the thorough inspection and start the scheduled host load test. If he can do it one day earlier, the pressure on his head can be reduced.
Now the company's party committee, board of directors, and superior leadership departments are calling almost every once in a while to inquire, which really makes him a little overwhelmed.
