  • The paper evaluates the perception of safety by cruise companies on board a ship and its organizationalmanagement. The approach on the probability of a negative event incurring on shipping companies, pas-sengers and environment affecting safety and it requires adequate and well-timed procedures on board.The methodology is based on negative binomial regression model on cross sectional data observed in tperiod based on frequencies of the events. The variables considered are collision, death, gastrointestinalnorovirus, mechanical problems, fire, wounded, and general accident as dependent variable. This modelreflects the condition that the event happens not infrequently in a certain period of time
