Recently, as the dry dock gate No. 3 of Putuo Changhong slowly opened, the large pipe-laying vessel "Chersky" completed its intense repair process inside the dock and slowly exited the dock.
"Chersky" is the first large-scale pipe-laying vessel that Putuo Changhong has repaired this year. The vessel has 10 propellers, which is 5-10 times that of ordinary ships. Due to its special structure and high repair difficulty, it has attracted great attention from the entire company. Before entering the dock, the ship repair production department, technical quality department, and electromechanical workshop held multiple preparation meetings for the dock clamp project. The project team planned in advance, broke down the drawings, and organized the material list. For the repair plan of the 10 propellers, the project team also developed detailed plans for all repair links that could affect the dock period. Before the ship entered the dock, the dock clamp construction team increased from the standard 18 people to 42 people to fully ensure the underwater work in the dock. The electromechanical workshop also pre-purchased 20 hand hoists and 60 steel wire rope slings to meet the needs of the project. At the same time, the three bases coordinated and shared lifting equipment resources to fully ensure the lifting needs of the 10 propellers.
As the main force in the dock work, many dock clamp supervisors in the electromechanical workshop worked around the clock, methodically carrying out their tasks. The remaining construction personnel worked in two shifts, racing against time. One shift was responsible for the main propeller repair project, while the other shift was responsible for the disassembly of the side propellers. Faced with the disassembly of each lifting propeller weighing 35 tons, the dock clamp construction process was detailed into seven steps: oil draining, lowering to the dock bottom, removing the blades, removing the sealing device, cleaning, inspecting, measuring, and non-destructive testing of moving parts, owner inspection, and reinstallation. After several days of racing against time, good news came frequently from the dock repair: all 10 propellers were completely disassembled in just 4 days! On the 5th day, the two main propellers were reassembled! On the 7th day, the bow side propeller was reassembled! The efficient operation provided ample construction conditions for subsequent sandblasting and painting work.
At the summary meeting before exiting the dock, the owner couldn't help but give a thumbs up: "The dry dock machinery job is perfect!"
The dock repair of this vessel greatly improved the overall level of the Putuo Changhong ship repair team, laying a solid foundation for the subsequent repair of similar vessels.
