To determine the risk involved in operations around offshore structures, static and dynamic traffic models can be used to assess the individual probabilities of incidents. This paper describes the underlying models to determine ramming (powered) as well as drifting collision frequencies for fixed objects at sea based on static traffic databases or AIS data. Static representations of the traffic allows for different risk models and accident statistics in determining the frequency of collision of a fixed object. AIS data, which shows the actual paths sailed by ships, can replace this static traffic database by a more dynamic risk model. As an example, this paper describes the approach for the risk assessment of an existing and future offshore installation.
