Introduction to IWRAP
The objective of IWRAP is to provide the user with a tool that assist in quantifying the risks involved with vessel traffic in specific geographical areas. On the basis of a specified traffic intensity and composition the tool allows the user to efficiently evaluate and estimate the annual number of collision and grounding in the specified navigational area.
In order to properly quantify the grounding and collision risks, rational criteria for prediction and evaluation of grounding and collision accidents have to be developed and the inherent consequences should to be analysed and assessed (see also Formal Safety Assessment).
| It should be noted that IWRAP only addresses collision and grounding frequencies, it does not support any analysis of the consequences of these groundings and/or collisions. |
Using the IWRAP (GRISK) software the frequency of collision or grounding may be evaluated for vessels operating in a specific waterway.
The main benefit of the formulated procedure is that it allows comparisons of various navigational route layouts by assessing the relative frequencies of collisions and groundings.
