The bow and stern thruster system for the 40,000-ton self-discharging vessel built by CSSC Chengxi was designed by Ruiyi and the related equipment was packaged and produced by Ruiyi. During the design process, Ruiyi maintained thorough communication with the shipowner, the design institute, the shipyard, and the classification society, actively incorporating their optimization suggestions. Ruiyi tailored a bespoke bow and stern thruster system specifically for this vessel. During the sea trials, the entire bow and stern thruster system operated smoothly, and all performance indicators met both the design specifications and the actual operational requirements of the vessel. Chengxi Shipyard highly praised Ruiyi’s equipment performance and integrated packaging capabilities for the bow and stern thruster system.

Report | 18 billion! The world’s most advanced single-site shipyard! Construction of Phase II of this “shipbuilding treasure land” has begun.

On January 4—the first working day of the new year—the groundbreaking ceremony for Phase II of the Changxing Shipbuilding Base, a major project listed by the National Development and Reform Commission, was held on Changxing Island in Shanghai. This project is another landmark initiative aimed at implementing the spirit of the strategic cooperation agreement between China Shipbuilding Group and the Shanghai Municipal Government, promoting the optimization and restructuring of shipbuilding enterprises based in Shanghai, and facilitating their transformation and development. It also underscores the thorough implementation of national strategies such as building a strong maritime nation, a strong science and technology nation, military-civilian integration, and Made in China 2025, thereby driving high-quality development of China’s shipbuilding and offshore engineering industry. Moreover, this marks the full-scale launch of the relocation project for Hudong-Zhonghua Shipbuilding (Group) Co., Ltd., a subsidiary of China Shipbuilding Group, to its new site—the Hudong-Zhonghua New Factory Area.

Electric vessels are becoming a new growth driver for the shipping industry.

Electric vessels are becoming a new growth driver for the shipping industry.

Against the backdrop of the global shipping industry accelerating its transition toward a green and low-carbon future, electric vessels—with their core advantages of “zero emissions, low noise, and high energy efficiency”—are emerging as a key growth driver that is helping the shipbuilding industry break through traditional growth bottlenecks. According to forecasts by EVTank, by 2026, China’s electric vessel market will surpass 36.75 billion yuan, with lithium-battery demand reaching 11.2 GWh. Behind these figures lies a triple resonance of technological breakthroughs, policy support, and market demand.
