| Abstract | This work presents a risk analysis model for ships, focusing on the scenarios where the crew interacts with the alarm and monitoring system. According to statistics of classification societies, humans are largely responsible for accidents on board and, therefore, are considered a major component of the safety of vessels. The relevance of the human element is given by the fact that human decisions and actions are related to the cause of accidents, either being the direct causative factor of failure or influencing the probability of failure, and the prevention of accidents or mitigation of the consequences. The alarm system is a mandatory component of certified vessels, with direct participation in an accident. It supplies information for the decision making process of the crew, considering their actions to recover the system. The study of the interactions between this automation equipment and the human element on board provides guidelines to managers and owners to invest in proper security systems and policies that influence human behavior, and therefore the safety on board. The model, inspired in accident reports, has as starting point a sequential structure of the accident, and takes into account a typical and simplified sequence of events, starting from a failure in the physical system. The human element is incorporated into the risk analysis through techniques of human reliability analysis, which place man as another component of the system, or the "liveware" interacting with software and hardware. From this point of view, a socio-technical approach is applied, considering that a ship is composed of not only its structure and machinery, but also of the entire crew. In order to illustrate the steps and assumptions to be done by an analyst applying the proposed model, the accident of the vessel Maersk Doha, occurred in October of 2006 in the United States, is analyzed. The report on the investigation of this accident is public and accessible via the Internet site of the Marine Accident Investigation Branch – MAIB. |
