On January 15th, to thoroughly implement the requirements of the "Implementation Plan for Special Inspection Work on Ships Carrying Dangerous Goods" and promote the effective execution of a fully closed-loop safety responsibility management system, the Fuchi Maritime Department collaborated with surveyors from China Classification Society (CCS). Together, they went to Anshun Shipyard to conduct a comprehensive special inspection of a hazardous materials vessel undergoing dry-dock repairs, aiming to build a multi-stakeholder safety governance ecosystem benefiting maritime authorities, ship inspection bodies, and shipyards through industry integration. This special inspection strictly adhered to the implementation plan's requirements, focusing on the core safety risk points of hazardous materials vessels and conducting an all-element, penetrating investigation. During the hull structure inspection phase, the inspection team examined the condition of deformed and corroded hull plates and the weld quality at key locations, with particular emphasis on verifying the structural strength and sealing integrity of cargo hold areas to prevent potential leakage hazards. Centered on the core requirements of fire and explosion prevention, the inspection team meticulously checked the completeness of firefighting equipment configurations, the operational parameters of ventilation systems, and the sealing performance of pipelines to ensure all safety facilities met statutory inspection standards. Given the specific characteristics of hazardous materials vessels, a special verification was conducted on the sensitivity of marine gas detection alarms, their alarm response speed, and the effectiveness of their calibration, ensuring the accurate and reliable monitoring and early warning functions for combustible, toxic, and harmful gases. Simultaneously, the team strictly cross-referenced the ship's design drawings and statutory certificates, conducting a comprehensive review to ensure consistency between the actual ship's structure, equipment configuration, and technical documentation, thereby guaranteeing the vessel's technical condition complied with regulations. During the inspection process, the collaborative mechanism of "maritime supervision + ship surveyor technology" played a key role. Law enforcement officers from the Fuchi Maritime Department leveraged their daily regulatory experience to precisely target high-frequency risk areas, while CCS surveyors provided professional support for equipment parameter verification and structural safety assessments based on ship survey technical rules, enabling real-time discussion and joint analysis of technical challenges discovered. For identified deficiencies such as inadequate equipment maintenance, improper routing of certain pipelines, and incorrect placement of equipment, the inspection team provided on-site rectification recommendations, clearly defining deadlines and re-inspection requirements, thereby establishing a fully closed-loop management chain of "inspection-feedback-rectification-re-inspection-closure" to ensure comprehensive hazard resolution. Moving forward, the Fuchi Maritime Department will continue to refine its regular joint inspection mechanism with CCS, transforming the results of special inspections into long-term regulatory effectiveness, and continuously optimizing the fully closed-loop safety responsibility management system. Through the power of industry integration, it will promote a shift in waterway safety governance towards a "proactive defense" model, building a solid barrier for the high-quality development of Yangtze River shipping.
