Welcome to the IWRAP Mk2 Wiki site.

IWRAP is a modeling tool useful for maritime risk assessment. Using IWRAP you can estimate the frequency of collisions and groundings in a given waterway based on information about traffic volume/composition, route geometry and bathymetry.

This Wiki provides some guidance on the use of the IALA Risk Management Tool IWRAP
