Recently, the container ship “Violeta,” with an age of over 25 years, slowly sailed into COSCO Shipping Heavy Industry (Shanghai) Co., Ltd., embarking on a highly significant “revitalization” journey. This repair project is large in scale, complex in systems, and extremely challenging to coordinate. It is not only a rigorous test of the shipyard’s comprehensive capabilities but also a critical battle against time.
The project encompasses key tasks such as routine maintenance of the main engine cylinder heads and pistons, auxiliary engine crankshafts, and numerous piping systems and heat exchange equipment. The multitude of construction elements placed extremely high demands on the superintendent group for project advancement. Facing these challenges, the superintendent group responded calmly and swiftly. Leveraging the company’s robust resource platform, they organized multiple specialized planning meetings. Aligning with the tight ship schedule, they scientifically decomposed the overall project down to each process node and precisely allocated construction teams and crane resources, laying a solid foundation for the efficient and orderly progress of the project.
During the main engine cylinder lifting operation in the engine room, the superintendent group encountered the problem of insufficient crane lifting capacity. The traditional disassembly and skidding plan was time-consuming and labor-intensive, severely hampering the project’s progress. After detailed on-site inspection, the superintendent group made a decisive decision to open a process hole, overcoming the difficult barging problem. This doubled the lifting efficiency, saved precious time for subsequent work.
However, the tests did not stop there – after reinstalling the cylinder heads and pistons, during the ship’s side pressure and oil pressure tests, water jackets in two cylinder liners were found to be leaking. Confronted with this unplanned contingency, the superintendent group demonstrated the very strong reaction ability and a strong sense of collaboration. They quickly adjusted the construction plan, established a specialized task force, and initiated an emergency work mode. All personnel worked diligently and fought hard. In the end, they not only efficiently completed the replacement and reinstallation of the seals but also achieved zero leakage in the pressure and oil tests through rigorous testing. The main engine trial was successful on the first attempt, firmly securing the critical schedule node and ensuring the ship’s departure on time.
Attention to detail reveals true craftsmanship. During the renewal project for the cargo hold measuring pipes and vent pipes, the superintendent group carefully discovered that the corrosion of some pipelines inside the holds far exceeded expectations, posing long-term safety hazards. The superintendent group proactively took responsibility, immediately communicated with the shipowner, and jointly developed a comprehensive overall renewal plan. Throughout the construction process, the superintendent group maintained strict control over welding procedures and construction quality. Ultimately, this project passed inspection successfully on the first submission, with both pipeline pressure and sealing meeting optimal standards.
The successful departure of the MV Violeta is an action guideline for the COSCO Shipping Heavy Industry (Shanghai) superintendent group in practicing “completing every task with high quality and efficiency,” and it is the most powerful response to the shipowner’s trust. In future work, COSCO Shipping Heavy Industry (Shanghai) will always uphold the philosophy of “striving for perfection, putting customers first,” continuously optimize work processes, improve service quality and efficiency, repay the trust of every customer with excellent quality, and steadily advance towards the goal of building a flagship green, low-carbon, and intelligent ship and offshore engineering repair and conversion facility!
