Dalian Shipbuilding Industry Group Co., Ltd. recently delivered the 7th 4250TEU container ship built by China Shipping Group. This vessel marks a significant milestone in the company's shipbuilding capabilities. From the day of its launch, the ship completed the engine trial, empty ship weighing, and structural strength testing within just one month. It set a new record for the shortest construction cycle and achieved an impressive 55-day underwater construction period for the series.
The 4250TEU container ship is part of Dalian Shipbuilding Heavy Industry’s three major ship series. Through mass production, the company has now reached construction standards comparable to those of South Korean shipyards. This achievement is not only due to years of continuous improvement in design and production management but also because of ongoing optimization in the shipbuilding process. These efforts have led to a major breakthrough in efficiency and quality.
The No. 18 4250TEU container ship, which was recently handed over, is currently undergoing final checks. The ship successfully completed the boiler compartment installation after the superstructure lighting was finished. At the end of the ground group, the exhaust pipe and boiler room armor were sealed and tested. Insulated white iron and furnace floor finishes were completed, and all deck corridor constructions were finalized. Lifeboats and rescue boats were installed and positioned before the building closure, ensuring full readiness for sea trials.
As a result, the superstructure of Dalian Shipbuilding Heavy Industry’s 4250TEU container ship has reached international standards in terms of construction integrity. The ship is now fully prepared for sea trials within a week of completing the underwater operations.
In the rudder work for the No. 18 ship, from the initial hull assembly to final inspection, improved organization and procedural methods allowed the ship to complete the rudder operation onshore within 9 days. This marks a new milestone in the company's history, laying a solid foundation for improving the integrity of the launching process and reducing the underwater construction cycle.
