en.Wedoany.com Reported - On July 8, the full-revolving semi-submersible crane vessel "Si Hang Yong Sheng," classed and inspected by the Zhuhai Branch of China Classification Society (CCS), was delivered in Jiangmen, Guangdong. This vessel is the largest of its kind in China to date, independently developed and built by CCCC Fourth Harbor Engineering Co., Ltd., and entered into CCS class, with the capability for unlimited navigation area deployment.
The "Si Hang Yong Sheng" is a 2,200-ton class multifunctional offshore crane vessel, with an overall length of 110 meters, a molded breadth of 43.8 meters, a molded depth of 8 meters, a design draft of 5.8 meters, and a maximum operating submergence depth of 28.6 meters. It is equipped with a 4,800-square-meter ultra-large continuous flat deck and a high-performance full-revolving luffing crane at the stern, with a maximum lifting capacity of 2,200 tons, capable of undertaking the transport of ultra-large and ultra-heavy offshore components weighing up to 10,000 tons. Its comprehensive operational performance ranks first among similar vessel types in China, making it key equipment for China's port hydraulic engineering and offshore construction projects. The vessel integrates multiple functions including full-revolving lifting, large-tonnage semi-submersible transport, and precision offshore hoisting, enabling operations such as submerging, surfacing, and the lifting and installation of large components, suitable for the transport and installation of ultra-heavy components like large caissons and offshore cylinders.
During the construction and inspection process, the CCS Zhuhai Branch established a dedicated inspection team that followed the project throughout, rigorously scrutinizing core technical modules such as semi-submersible operations, large-tonnage lifting, and intelligent ballasting. Based on code standards, the surveyors conducted comprehensive inspections of key components and core systems, including hull structure, lifting system, intelligent equipment, and power plant, identifying and rectifying potential hazards and resolving technical difficulties to ensure all performance indicators of the vessel met requirements. The team's professional competence and meticulous work were recognized by the shipowner, builder, and participating units.
The Zhuhai Branch of China Classification Society stated that it will continue to fulfill its vessel inspection duties in the next step, adhering to the policy of "Technology-based, Integrity-oriented, Distinctive, and World-class," leveraging its technical advantages to support the development of the high-end marine engineering equipment industry cluster on the south bank of the Pearl River Estuary and serve the construction of a "New Guangdong on the Sea."
