Jul 14,2026
7 month 8 In the morning, the French CMA CGM Group 23000TEU Super-large LNG Dual-fuel-powered container ship “CMA CGM LOUVRE” At Zhoushan COSCO Shipping Heavy Industry, the float-over repair project was successfully completed, and the vessel departed after casting off. This repair was finished ahead of schedule compared to the original timeline. 4 Completed on schedule, it has earned high praise from the shipowner for its exceptional craftsmanship.
“CMA CGM LOUVRE” The vessel is one of CMA CGM’s core transport assets; the ship’s captain… 399.9 Rice, ship width 61.3 Rice, equipped with GTT Mark III Type 18630 cubic meter LNG The fuel‑cell vessel is a benchmark ship design that embodies the principles of green shipping.
This maintenance overhaul faces complex safety challenges. Upon the vessel’s arrival at the shipyard, LNG Approximately remains in the fuel tank. 2600 metric tons of liquefied natural gas, which does not meet the operational requirements for direct inerting or tank heating, is a typical case of… “ Bring gas into the plant ” High-risk operating conditions. Faced with severe challenges, Zhoushan COSCO Shipping Heavy Industry responded swiftly by establishing a dedicated task force, maintaining close coordination with the shipowner, and jointly developing a rigorous fuel‑management plan. The company precisely delineated hazardous work zones and highly sensitive control boundaries, implemented round-the-clock dynamic monitoring of liquid cargo tank operating parameters, and instituted end-to-end closed-loop management for hot‑work operations such as welding, thereby erecting a robust safety barrier for all construction activities.
On the basis of strictly upholding safety standards, the core repair project progressed in an orderly manner. This overhaul encompassed cutting-edge tasks such as upgrading and retrofitting the shore‑power system, installing Hoerbiger pressure‑relief valves on auxiliary‑engine exhaust ducts, and completely replacing the offshore cooling‑system piping and associated valves. In response to island‑specific weather conditions and other factors, the project team leveraged its coordination capabilities to deploy key personnel in a scientifically sound manner, ensuring efficient inter‑departmental collaboration and close monitoring of critical milestones. As a result, all inspection‑required and commissioning items passed first‑time acceptance. The originally scheduled 10‑day timeframe was compressed to just six days, fully demonstrating the company’s robust project‑management expertise and meticulous construction standards.
The successful completion of this overhaul marks a significant leap in the company’s capabilities in LNG‑dual‑fuel vessel repair, moving from “low‑inventory monitoring” to “precise control of ultra‑large inventories.” Compared with previous projects, the 2,600‑metric‑ton LNG storage capacity places exponentially more stringent demands on safety‑redundancy design. This real‑world breakthrough not only validates the maturity of the company’s full‑range operational maintenance system but also yields invaluable experience for similar operations across the industry, thereby strengthening Zhoushan COSCO Shipping Heavy Industry’s core competitiveness as it continues to deepen its presence in the green ship‑repair market.
