The Ship During The Cargo Operations In Port:The Stability Plays Its Role

Abstract

This paper focuses on the possibility of ships accidents due to stability loss while they are doing cargo operations in port. In the best of cases, stability calculations for the departure condition of the port, for an intermediate condition corresponding to the half of the voayage, and for the arrival condition to the port, are made. However, the evolution of the ship's stability while carrying out cargo operations is taken into account only for very specific cases and circumstances. In the present work, it is considered and recommended the necessity of computing the stability for the different phases of the cargo work. It is also made a qualification of the risk operations through a methodology based on the limit planes, that allows to forecast easily, but without quantification, the effect of each individual or group of operations under the actual situation of the ship, getting, finally, rules to help the master to make his ship more stable keeping the minimum values when she is operating in port.
