Abstract

In our paper The Risk Homeostasis Theory1, it was accepted that the behaviour of people involved in the operation of cargo carrying ships is conditioned to maximize the economic benefits of the amount of risk assumed in the transport. As a follow-up to that paper, the objective of this one is to investigate the relationship between the level of compliance of the cargo carrying vessels with international standards and the degree of severity of the incidents they are involved in. For this purpose, we analyse the same sample of 2,584 cargo carrying ships involved in incidents during 2005 and 2006 used in that investigation. The variables of the Paris MoU to identify substandard ships are used again to measure the standard level of ships and the degree of seriousness of incidents is determined by the number of days ships are under repair.

22 A Receiver Operating Characteristic (ROC curve) is a graphical plot of the sensitivity vs. (1-specificity) for a binary classifier system as its discrimination threshold varies. A signal detection theory provides a precise language and graphic notation for analysing decision making in the presence of uncertainty. By tradition, the plot shows the false positive rate (1-specificity) on the X axis and the true positive rate (sensitivity) on the Y axis. In this paper, sensitivity is the proportion of serious accidents with scores greater than the cut-off and, 1-specificity is the proportion of not serious accidents in vessels with score greater than the cut-off. Cut-off values go from 4 to 19; for instance, cut-off 4 is equivalent to assuming that every vessel is involved in serious accidents and cut-off 18 is equivalent to assuming that every ship is involved in not serious ones. Both extremes are unsatisfactory.Google Scholar

25 Statistical calculations to obtain β coefficients were made assigning the values of the categorical variables shown in Figure 28 to each ship, which means that for the variables Flag, Class, Age and Size the coefficients will have 3 values and for the variable Type only one value.Google Scholar
26 Model was estimated using a backward stepwise (Wald) method. In the output of Table 18, B is the estimated coefficient, with standard error S. E. The Wald statistic is significant when less than 0·05, which means that the parameter is useful to the model. Exp(B) is the predicted change in odds for a unit increase in the predictor and when its value is less/greater than 1, it means that increasing values of the variable correspond to decreasing/increasing odds of the event's occurrence.Google Scholar
27 The International Safety Management Code (ISM) was made mandatory by Chapter IX of the SOLAS Convention. It requires a safety management system to be established by the shipowner or any person who has assumed responsibility for the ship. The deviations from specified requirements are defined as nonconformities.Google Scholar
