The risk data of each of the four categories (Life, Property, Environment and Port Business) is analysed within the Hazman software to obtain four indices for each hazard as follows:
a) The average risk value of the four categories in the ‘most-likely’ set.
b) The average risk value of the four categories in the ‘worst credible’ set.
c) The maximum risk value of the four categories in the ‘most-likely’ set.
d) The maximum risk value of the four categories in the ‘worst-credible’ set.
Average risk values are sensitive towards hazards that score moderately or highly over a number of categories, whilst the maximum risk values are sensitive towards hazards that score particularly high in any category.
These values are combined in the Hazman software to produce a numeric value representing each of the four indices. The hazard list is then sorted in order of the aggregate of the four indices to produce a Ranked Hazard List, in descending order, with the highest risk hazards prioritised at the top. This list, comprising 68 hazards is reproduced in full in Annex B. This Ranked Hazard List describes the Risk Profile of the Harbour with regard to navigational operations
