Wuhan Changjiang Waterway Rescue and Salvage Bureau is a Wuhan-based public-sector unit operating within the Changjiang Waterway Bureau system that administers navigation along the Yangtze River, the principal inland artery of central China. The Wuhan base is one of three full-department-level on-water emergency rescue centres established along the river, alongside Wanzhou upstream and Nanjing downstream, and supports waterway engineering, navigation mark installation, dam cofferdam construction, underwater obstacle removal and emergency response on the middle Yangtze. Within the marine and inland-water services market, the bureau extends its operational base into commercial underwater inspection work for ships, offshore construction units and infrastructure assets along the river corridor, deploying commercial divers and survey craft for in-water hull, rudder and propeller examinations, bottom condition surveys and class-attended underwater inspections in lieu of drydocking. Inspection scopes are documented with video and photographic records prepared in formats familiar to attending classification surveyors and Chinese maritime authorities. Wuhan Changjiang Waterway Rescue and Salvage Bureau operates within the directory of suppliers recognised by CCS for in-water survey work, allowing its diving teams to support periodical survey programmes for tonnage trading on the Yangtze. Through its rescue and salvage mandate, engineering capability and class-recognised dive services, the bureau provides ship operators and infrastructure owners with a single regional contact for emergency response, salvage and routine underwater inspection in the Wuhan section of the Yangtze. The base maintains diving support craft, multi-beam survey assets and lifting capacity needed for emergency response on the river, and applies that equipment portfolio to commercial inspection contracts for shipowners, terminal operators, bridge authorities and dredging companies working the Wuhan reach and the wider middle Yangtze corridor.
