Exploring marine accident causation: A case study
2016
Studies underpinned by systems thinking have significantly altered the viewpoint of safety for sociotechnical systems. Safety is characterized as an
emergent property (Leveson et al., 2006) that arises
when the system components interact with each
other (Dulac, 2007; Qureshi, 2007). The unsafe
behaviors and inadequate control actions occurred
at various levels within the socio-technical system
allow it to migrate towards a state where a simple
deviation can lead to a cataclysmic loss (Rasmussen, 1997). Accordingly, accident causation should
be seen as a complex process (Woods et al., 1994;
Leveson, 2011) involving actors from all levels
within the socio-technical system (i.e., designers,
legislators, managers, operators, etc.). Traditional
even-based accident analysis models, i.e., Fault
Tree Analysis (FTA), Event Tree Analysis (ETA),
Failure Modes and Effects Analysis (FMEA) have
revealed their limitations to capture the hazardous
and dysfunctional interactions between and among
system components that led to the accident (Leveson, 2011). Moreover, the events that are selected
to explain the accident causation are also subject
to bias.
