Examples of bow-tie risk analysis at maritime transport

There are different approaches to risk assessment. The SOLAS Convention is the most important safety instruments at maritime transport. The biggest risk is a major navigational incident because it can result in fatalities and pollution. Possibly the major cause of collision incidents is not fully understanding and complying the COLREGS rules. It is not possible to create a simple flowchart to define a suitable approach to risk assessment of a ship. However, some of broad factors can be used to aid the selection of a suitable risk assessment approach in maritime transport. In the literature, we can find many methods and applications for maritime transportation risk analysis. There is a recent focus on foundational issues in risk analysis, especially for intensified research on fundamental concepts and principles. This paper presents the attempt of applying the Bow-Tie methodology at maritime transport. The benefits of using Bow-Tie diagrams for risk assessment have been showed at use, for many of technical systems and processes. This methodology known as barrier diagrams, provide a readily understandable visualization of the relationships between the causes of the failure's event, the escalation of such events to a range of possible outcomes, the controls preventing the event from occurring and the preparedness measures in place to limit the consequences. The Bow-Tie is very useful for structured assessment and communication of risks.
