On December 23, the LNG dual-fuel bulk carrier “Novaterra Mountain,” whose repairs were undertaken by the company for the first time, successfully completed all repair work and departed the shipyard smoothly.

The vessel “Novaterra Mountain” has a total length of 300 meters and a molded breadth of 50 meters. It is equipped with two large LNG storage tanks, each with a capacity of 3,100 cubic meters. The repair work on this vessel poses significantly greater technical challenges and complexity than those typically encountered with conventional ships. When the vessel first arrived at the shipyard, the original plan was to replace only about 40 tons of steel in the bulbous bow structure, with a scheduled repair period of 15 days. However, after a thorough inspection, it became clear that the scope of the replacement work had increased substantially. The total weight of replaced steel structures exceeds 150 tons. and faces two major technical challenges: “prefabrication without blueprints” and “PSPC-standard coating.”

Faced with the increased workload and more complex technical requirements in this round of repair projects, the company’s leadership has attached great importance to the project and made forward-looking arrangements. On the eve of the vessel’s arrival at the shipyard, the Production Department, Safety & Environmental Protection Department, Technical Department, Quality Management Department, and all production workshops jointly convened a special meeting on safety production planning. At the meeting, they conducted a comprehensive assessment of construction challenges and identified key safety control risk points. They also proactively coordinated and allocated high-quality resources, clearly defined responsibilities and milestones for each stage, thereby laying a solid foundation for the smooth progress of subsequent construction work.

During the construction period, the single-vessel project management team fully leveraged its core scheduling role, implementing refined management and dynamic scheduling. Through a 24-hour uninterrupted collaboration and inspection mechanism, the team efficiently addressed various on-site challenges. All construction personnel worked tirelessly day and night in close coordination, successfully completing the critical procedures of outer plating welding inspection and non-destructive testing at 11:00 p.m. on December 20. The next day, they smoothly achieved the completion inspection of the internal steel structure, thereby securing a valuable construction window for the subsequent painting operations compliant with PSPC standards.

On December 23, with the completion of all dockyard works, the vessel “Novaterra Mountain” successfully exited the dry dock five days ahead of schedule, achieving a highly efficient seamless transition from dock exit to immediate departure. Throughout this repair project, stringent safety management was maintained, production milestones were clearly defined, and quality control was rigorously enforced. This fully demonstrated the company’s strong integrated capabilities in large-scale marine casualty repairs—including multi-disciplinary collaboration, PSPC coating application, and urgent schedule compression—earning unanimous high praise from both the shipowner and the classification society for its professional, efficient, and reliable execution.

The successful completion of the first LNG dual-fuel vessel repair project. This delivery marks a significant breakthrough for Xinhong Heavy Industry in the field of high-tech, value-added, and clean-energy vessel repair, and it also provides valuable experience for undertaking similar projects in the future. The company will continue to uphold the philosophy of “pursuing excellence and putting customers first,” continuously enhancing its technological capabilities and management standards, and delivering shorter turnaround times and higher-quality ship repair services to shipowners worldwide.
