FORMAL SAFETY ASSESSMENT OF A FISHING VESSEL 35

According to the flowchart of the FSA process, a test case study on a generic vessel can be
defined in Fig. 2.

The first step of the proposed analysis is the hazard identification (HAZID). This consists of
determining which hazards affect the fishing vessels‟ activities using „brainstorming‟
techniques. Trained and experienced personnel are required to systematically identify all
potential failure events with their influences on system safety and performance. Information
produced from the hazard identification phase will be processed to estimate risk.

Various safety analysis methods include:
    a) Preliminary hazard analysis (Henley and Kumamoto, 1992; Smith, 1992; Villemeur,
         1992)
    b) Fault tree analysis(Henley and Kumamoto, 1992; Smith, 1992; Villemeur, 1992; Köse,
         1998)
    c) Event tree analysis(Henley and Kumamoto, 1992; Smith, 1992; Villemeur, 1992;Köse,
         1998)
    d) Cause-consequence analysis(Henley and Kumamoto, 1992; Smith, 1992; Villemeur,
         1992)
    e) Hazard and operability analysis(Henley and Kumamoto, 1992; Villemeur, 1992)
    f) Boolean representation method(Wang et al., 1995)
    g) Simulation analysis(Henley and Kumamoto, 1992; Villemeur, 1992)

Accident categories that are considered in this study include:
         Flooding,
         Foundering,
         Grounding,
