The job of patching the leaks is much more difficult than imagined, especially when the work involves fuel tanks.
As the key supply equipment for main engine fuel, the fuel tank contains a large amount of light fuel, that is, diesel.
Although Zhang Yujie had foreseen the danger a long time ago and pumped out all the diesel inside and transferred it to the tanker truck on the dock, the remaining oil and gas inside was still very dangerous.
The chief engineer is naturally aware of this.
Many oil and gas explosions, both domestically and internationally, are related to the residual oil and gas in storage equipment. Especially when repairing storage equipment, you must pay more attention to this aspect.
Although Zhang Yujie repeatedly warned that safety must be the first priority when working, the maintenance workers could only trade time for safety.
They first cleaned out all the remaining oil and vapor in the fuel tank, and then thoroughly cleaned the fuel tank without leaving any oil or vapor residue.
In addition, the cabin where the fuel tank is located also needs to be cleaned and evacuated. Only after the entire working environment is determined to meet safety standards can the real repair work begin.
Among them, the Blue Whale also needs to ensure that there will be no leakage of sewage and detergents during the cleaning process. This is why Zhang Yujie originally requested to install oil-blocking equipment around the Blue Whale. Once the surrounding environment is polluted, this will
The trouble is huge.
These preparations were carried out step by step, and time passed little by little.
The Xiaobai Building is also very anxious. The leaders still need to receive the distinguished guests from all walks of life with smiles. They are always worried about the situation of the Blue Whale. The contact with Zhang Yujie has not been interrupted. Every other
Ask about the situation every hour.
Everyone asks about different things, but basically there is only one theme.
That is whether Blue Whale can carry out the host load test within the specified time.
Even Zhang Yujie, who was on the scene, did not dare to make this guarantee. He could only say that he would try his best to achieve this goal. Whether it can be achieved depends on the speed of the engineering and technical personnel.
The repair work on the fuel tanks on the Blue Whale is in full swing, but the progress is really making people scratch their heads.
But for such a speed, no one dared to rush it, not even Zhang Yujie, who is the chief engineer.
After all, this is no ordinary job, as long as there are more people, there will be greater strength.
In addition to the time required for a secure environment, this kind of delicate repair work also requires a high degree of concentration and technical level. Otherwise, once the repair fails, the consequences may be greater than the original ones, and by that time it will be an unmanageable consequence.
.
Zhang Yujie can only stay on the Blue Whale and pay attention to the maintenance status at all times, ensuring that any materials and conditions required during the maintenance process are guaranteed as soon as possible to ensure the progress of the maintenance as much as possible.
The repair work of the Blue Whale's fuel tank is in progress, and on the dock outside the Blue Whale, preparations for the main engine load test cannot be stopped.
Everyone knows that the main engine load test is one of the most important nodes in the construction process of the Blue Whale. Only if the heart of the Blue Whale beats normally can the subsequent tests of various equipment be carried out smoothly until the owner's acceptance standards are met.
A powerful weapon heading into the deep sea.
For such an important day, Fuhai Group also invited many distinguished guests, mainly the future owners of the Blue Whale and representatives from major domestic universities. After the host is launched, it means that their future plans are in order
advance forward.
Zhang Yujie stood on the platform and looked at the work on the dock, feeling a little uneasy. However, there was nothing he could do at this time and he could only supervise the maintenance work as much as possible.
With everyone's eager anticipation, the maintenance continued until the afternoon. The hard work paid off and the work was finally coming to an end. This made Zhang Yujie, who had been staring at the Blue Whale for more than ten hours, relieved.
He laughed with relief and immediately picked up the phone and called Lu Zhengtao.
"Director Lu, the maintenance work on the fuel tank is nearing completion!"
Lu Zhengtao felt much more relaxed after hearing the news and said "Okay!" "Okay!" "Okay!" several times in a row.
"Lao Zhang, I immediately informed the company management and the Whale Dream Project headquarters that the Blue Whale main engine load test will proceed normally the next day. You will be there to watch the whole thing be completed successfully!"
Hearing that the host load test could be carried out normally, Xiaobailou suddenly burst into joy, and everyone's worries were finally put down.
Although it was said that it could continue, the maintenance work was not completed immediately. The maintenance workers on the Blue Whale were still working sweatily without any expression of joy.
I know that the maintenance work is not completed until after 5 o'clock in the afternoon. Although the maintenance is completed, it still needs to go through a key procedure, that is, inspection.
Before that, Wei Yuhui and others were notified and were sent to the Blue Whale again by special vehicle to conduct various inspections on the repaired fuel tank.
The scope of the inspection was much narrowed this time. Wei Yuhui immediately conducted various tests on the repair parts, and finally confirmed that the repair parts fully complied with the specification requirements, and the leakage problem of the fuel tank had been fully resolved.
After receiving this test result, smiles appeared on everyone's faces, and they finally lived up to the trust of the group leaders.
Subsequently, the workers responsible for outer protection began to re-lay the insulation material on the bulkhead of the fuel tank, and the workers responsible for cleaning conducted a comprehensive cleaning of the entire work site to ensure that the entire cabin was spotless, just like before.
The engineers finally left their names in the maintenance record book to confirm their responsibility for the entire maintenance process.
By this time it was already ten o'clock in the evening, and the entire maintenance work was officially completed.
After a day and night of intense work, and more than 20 hours after the oil pollution was discovered, the huge hidden danger in the fuel tank was finally completely eliminated.
Zhang Yujie returned to Xiaobailou exhausted. None of the company's party committee and board members left, waiting for him to come and report the entire process.
Through various investigations and inspections, and careful inspection of the leakage point of the fuel tank, it was finally determined that the leakage in the fuel tank was an extremely rare accidental phenomenon.
The cause of the accident was that a leak accidentally occurred in the steel plate used for the fuel tank bulkhead during production, and the leak was so subtle that it could not be discovered without precision instrument inspection.
This caused this huge hidden danger.
Lu Zhengtao highly praised the sense of responsibility of the Blue Whale night inspection personnel, asked all employees of the group to learn from them, commended Han Dongdong for discovering hidden dangers, and then emphasized the importance of daily inspections.
The company's party committee and board of directors, as well as the Whale Dream Project headquarters, unanimously believe that this incident was a near miss. If this incident had not been discovered, the consequences would have been disastrous, and it also sounded a wake-up call for Fuhai Group.
Although it is impossible to conduct comprehensive re-inspections of all equipment with current methods, inspections of equipment and consumables can be strengthened to detect possible problems in advance, so that larger accidents can be avoided.
