"I support self-repair. It is not the foreign repair teams that know the ship equipment best, but our crews themselves, right?" At the "All Works to Projects" ship management discussion meeting of the Ship Branch of CCCC First Navigation Engineering Bureau Second Company, the simple speech of Wang Xiaoming, the chief engineer of "Crane 11", won everyone's approval. In the heated discussion on ship self-repair and ship repair, everyone was full of energy.
In the past, when equipment broke down, the crew would habitually seek help from the ship repair team, which naturally resulted in much higher repair costs. Since the beginning of this year, in order to implement the company's cost control requirements and ensure the integrity and utilization rate of the ship, the ship branch has proposed self-repair rewards, which can not only train the crew's practical skills, but also save the cost of ship repair.
During the construction of a project in Yantai, "Crane 11" was responsible for 24-hour lifting of pipe culverts. When laying anchors at night, Han Shui, the second mate who was operating the winch, suddenly found that several anchor machines had lost power, which would not only affect the movement and operation efficiency of the ship, but also cause the ship to drift and run aground under the action of wind and waves. "Engine department, this is the deck, the anchor machine has an emergency failure." After hearing the voice on the intercom, Wang Xiaoming immediately led the second engineer Li Junlin and others to the scene. After inspection, they found that the large coupling gear of the No. 2 main hydraulic pump was worn, causing the hydraulic pump to stop.
"What should we do? The place is too narrow. There are too many hydraulic equipment and pipelines that need to be disassembled and assembled to repair..." Looking at this "big project" in front of them, the crew was a little confused. Wang Xiaoming immediately contacted Wang Zerong, the chief engineer of the maintenance department, and decided to report for self-repair. "If there is a problem, we should solve it. We can't hesitate and wait. How about repairing it ourselves?" "What else can we say? Just do it!" Several people in the team discussed and determined the cause of the failure together, consulted the ship engine drawings and materials, and determined the maintenance plan. Electric welding, hand hoists, wrenches, screwdrivers... At this time, the engine room has become a ship's "operating room", and various maintenance tools are used in turn. At three o'clock in the morning, in an area less than one person wide, the crew removed the hydraulic pump, replaced the coupling, completed the final equipment calibration, and the project construction resumed smoothly.
The branch's maintenance department strictly limits voyage repairs and encourages self-repairs. It also shares self-repair cases of ships such as "Crane 11" in the ship group. "Jiaogong 79" also expressed his desire to "show off his skills."
In early July, at the breakwater project in the Hujiashan operation area of Dongjiakou Port in Qingdao Port, the "Jiaogong 79" responsible for towing the "Semi-submersible Barge No. 7" to transport caissons suddenly failed to control the direction of the right rudder propeller. Once the course deviates and emergency avoidance of obstacles occurs, the ship may face the risk of collision due to the inability to accurately control the direction.
"Quick, use manual steering!" Captain Han Xili and Chief Engineer Wang Qingcheng met to discuss and first take emergency measures. After helping "Semi-submersible Barge No. 7" complete positioning, "Jiaogong 79" found a safe location to anchor and began a thorough overhaul. After a thorough investigation, everyone planned to ask the manufacturer for their opinion. "We initially determined that it was a problem with the steering handle and suggested replacing a new handle, but it will take more than a month to ship." "Don't even think about a month. On-site construction can't wait for a day." After hearing the manufacturer's reply, the crew tried to replace the ship's handle, but found that the "culprit" was not the handle.
The crew decided to check the more than 60 lines on the hull one by one. After 11 hours of investigation, they found that there was a problem inside a signal line. The team tried to temporarily replace the external signal line. The repair problem that originally required a lot of time and cost was easily solved through the crew's self-repair.
After half a year of implementation, the new version of the ship self-repair management method has gradually gained popularity, and ships that did not pay much attention to self-repair have also started self-repair. "We have also set up rewards for ship self-repair, so that the maintenance manager and crew can improve their skills and increase their income." Manager Liu Jianguo said confidently.
