Assessing the Frequency and Material Consequences of Collisions with Vessels Lying at an Anchorage in Line with IALA iWrap MkII

This paper proposes a collision model for ships underway and temporary objects as an extension to state-of-the-art maritime risk assessment like IALA iWrap MkII. It gives a brief review of frequency modeling’s and consequence calculation theory as well as its applications, before it analogously derives a model to assess the risk of anchorage areas. Subsequently, its benefit is demonstrated by an example scenario.
