Abstract: | This article presents detailed results of a comprehensive analysis of recorded accidents of large oil tankers (deadweight
greater than 80 000 tonnes) occurring between 1978 and 2003. The analysis encompasses a thorough review of available raw accident
data and their postprocessing in a way to produce appropriate statistics useful for the implementation of risk-based assessment
methodologies. The processing of the captured data led to the identification of significant qualitative historical trends
of tanker accidents and of quantitative characteristics of large tanker accidents, such as overall accident rates per ship-year.
Data were also analyzed for all major accident categories separately, taking into account tanker ship size/type, the degree
of accident severity, and the oil spill tonne rates per ship-year; this led to the identification of heavily polluted worldwide
geographical areas as a result of large tanker accidents. |
