On November 8, 2025, the large mineral sand carrier "Helen" successfully completed all its repair work at our company, setting sail three days ahead of the original schedule.

"The Helen" is the largest vessel type among all the outer-plate silicone coating projects the company has undertaken to date. The ship boasts a deadweight tonnage of 297,000 tons, a length of 327 meters, and a molded breadth of 55 meters. This repair project encompasses a range of critical tasks, including applying silicone coatings to 35,250 square meters of the ship’s outer plating, dismantling and reinstalling propeller blades, replacing the stern shaft seal, installing anti-vortex fins, and overhauling the main engine’s crosshead bearings. The project spans multiple key areas—such as mechanical, electrical, and painting systems—and features an exceptionally complex overall structure, stringent technical and process standards, and an extremely tight schedule. As a result, it places extraordinarily high demands on the company’s efficiency in single-vessel project management and its ability to effectively integrate resources.

Faced with this challenging production task, the Production Department placed great emphasis on it, immediately organizing the production workshops to coordinate in advance, deploy resources scientifically, and meticulously plan the project. During the construction process, the Painting Workshop actively allocated manpower and equipment resources, fully leveraging the advantages of eco-friendly painting tools such as the boom lift and waterjet robots. They continuously optimized the construction schedule, rigorously enforced control over key painting milestones, and completed the ship-wide rust removal work in just 58 hours—representing an 18.74% improvement in efficiency compared to previous projects. This efficient execution not only secured valuable time for subsequent painting and coating operations but also ensured the smooth progression of the entire project. Finally, on November 3rd, the team successfully completed the two consecutive rounds of paint spraying. Meanwhile, the Mechanical & Electrical Workshop focused intently on critical dock repair tasks—including propeller blades, steering gear, and main engines—overcoming challenges like the complex, multi-layered scheduling conflicts with painting activities and intricate workflow transitions. They meticulously implemented specialized construction plans and robust safety measures, closely monitoring critical deadlines while maintaining round-the-clock operations to deliver all dock repair tasks with exceptional quality. Thanks to the seamless collaboration across the production system, the vessel "Helen" achieved a highly efficient transition from dry-docking straight into sailing, earning high praise from the shipowner.

This time, "Helen" The successful delivery of the vessel not only highlights the company’s robust project execution capabilities and efficient resource integration skills in the large-scale ship repair sector, but also paves the way for… The company has since gained valuable experience by undertaking similar high-end repair projects. Moving forward, the company will continue to uphold the philosophy of "striving for excellence and putting customers first," constantly enhancing both its craftsmanship and operational efficiency to deliver even higher-quality, more efficient ship repair services to shipowners.
