内河双舷侧大舱口船舷舱撑材变形原因分析及对策OA

In recent years,double-side large-hatch bulk carriers for inland water voyages have been increasingly engaged in the transportation of muck and crushed stones.Due to violent loading and unloading operations and the lack of safety production awareness among shipowners,the hull structures can be damaged,which can easily lead to safety risks.Taking two accident cases as examples,with 846 general bulk carriers reinspected in the Qingyuan area,this paper analyzes the common ship defects and the commonalities of instability and deformation of individual components that generally exist in the hull structures of bulk carriers for muck transportation,and puts forward proposed countermeasures,aiming at further improving the safety of ship structures and reducing the risk of ship fractures.
