China Classification Society facilitates the smooth delivery of the "Chongqing Emergency 012", the largest self-propelled crane ship in the upper reaches of the Yangtze River

Recently, the 800T crane ship "Chongqing Emergency 012", constructed and surveyed by China Classification Society (CCS), was successfully delivered. It will provide important support for maritime rescue operations involving super-large vessels in the Yangtze River Basin, marking a significant improvement in the engineering capabilities for large-scale transportation, bridge construction, and emergency rescue in the upper reaches of the Yangtze River

The "Chongqing Emergency 012" vessel, constructed with special funding from China's Ministry of Finance and Ministry of Emergency Management, is designed to enhance the safety production prevention and emergency response capabilities of the National Water Rescue Chongqing Long-Distance Team. With a maximum lifting capacity of 800 tons, a lifting height of 75 meters, and a 6.7-degree boom angle for bridge operations, it sets industry records for similar vessels in the upper Yangtze River. Capable of adapting to the region's complex hydrological and navigational conditions, the ship performs multiple tasks including large-scale equipment hoisting, waterway maintenance, and sunken vessel salvage. This breakthrough fills the gap of lacking large-scale rescue floating cranes in the upper Yangtze, significantly improving the shipping equipment system and emergency response capabilities in the region.

During the construction inspection phase, Chongqing Branch assembled a dedicated project team to conduct comprehensive and full-process supervision, focusing on the ship's core safety components. The vessel's crane boom, characterized by its exceptional height and length, complex operational conditions, and adaptation to the Yangtze River's upstream navigation characteristics, imposed stringent requirements on structural strength, safety performance, and equipment reliability. These challenges also posed significant difficulties for preliminary incline tests and mooring trials. To ensure smooth delivery, Chongqing Branch collaborated closely with the shipyard, design institute, and shipowner. Through specialized technical exchanges and on-site guidance, they optimized solutions while maintaining construction quality, efficiently advancing project milestones and providing technical support. This ensured the successful delivery of the "Chongqing Emergency 012" vessel.

Going forward, the Chongqing Branch will continue to prioritize the shipping development needs of the upper Yangtze River. By leveraging its technical expertise, it will provide robust ship inspection services to ensure the safety, smooth operation, and green transformation of the Yangtze's golden waterway, thereby driving the high-quality growth of the regional shipping economy.
