Research on safety risk management of restricted ships navigating in the yangtze river

After the opening of the 12.5m deep-water channel below Nanjing of the Yangtze River,the role of the Golden Waterway is further highlighted,and 200000 tonnage seagoing ships can reduce the load and berth at Zhenjiang Port.In recent years,the number of restricted ships entering the river has increased significantly.In 2021,the number of restricted ships led by the Yangtze River Pilotage will be 13914.According to the internal data of the Yangtze River Pilotage Center,the number of out of control restricted ships will reach 37 in 2021,bringing great pressure to the safety management of maritime,pilotage and other institutions.This paper takes the whole process of restricted ships entering the river as the research object,uses risk theory to classify the risk level of ships sailing,turning,crossing and possible out of control situations,and then puts forward corresponding countermeasures and suggestions,which can provide reference for the safety management of relevant departments.
