Deduction and prevention of container overboard accident during loading and unloading

Abstract

To prevent the recurrence of containers overboard accident during loading and unloading, taking the accident at Yueyang Chenglingji Teminal as the study object, the mechanical deduction is carried out. A kind of method to determine whether a container will overturn is put forward, including the criterion and the quantitative algorithm of the corresponding indicators, i.e. the allowable heel angles. By verifying, the estimated results according to the algorithm described in this article, are basically consistent with the Yueyang accident. Thereout a set of measures to prevent such accidents are provided, including adding allowable heel angles during loading and unloading in the loading manual, carrying out stowage plan and evaluating and controlling the ship floating state before operating, monitoring and adjusting of the ship floating state during operating.
