and from these different angles to try to imagine how things could go wrong. In this process it
is useful to think in terms of scenarios, i.e. sequences of events, which might lead to adverse
situations.
Consider as an example the offshore platform sketched in Figure 4.15.
Oil and gas productionFigure 4.15: Principal sketch of an offshore production facility.
Considering only the normal production phase a list of some pointers to exposure events are
given in Table 4.2 together with some of the corresponding exposures, events and
consequence categories.
The lists in Table 4.2 are by no means complete and are meant as an illustration only of how
the various hazard pointers may be applied in the identification of hazards. From Table 4.2 it
is noticed that several of the hazard pointers lead to the identification of the same exposures
and scenarios. This is quite natural and facilitates a thorough and redundant assessment of the
potential hazards.
