Directional Aspects of Collision Risk between Passing Ships and Platforms: a North Sea Case Study

摘要

The risk of collision with a ship is now estimated to be the singlernlargest source of risk for some North Sea offshore platforms. Currentrnprocedures for modelling risk due to passing ships are omni-directional,rnand no explicit consideration is usually given to the directions in whichrnthe ships are travelling relative to the faces of the platform. This paperrnexamines the effect of ship direction upon collision risk through a casernstudy using the COAST database and a simple new collision damagernmodel. It is found that collision damage risk can vary significantlyrnwith direction. The paper argues that there could be significantrnimprovements to the current practice in the modelling and estimating ofrncollision risk.
