The subject of oil pollution of thesea by the offshore industry is topical as a result of recent incidents both in the U.K and overseas. Whilst these incidents have primarily involved crude carriers, it has led to pressure to quantify the risk to the environment from the offshore industry in general. Here a method for the assessment of the frequency and size of oil spills from offshore installations is presented. It relies on previously reported spills to determine spill size/frequency information for a range of offshore activities, such as transport by pipeline, drilling and processing. Modification factors are used solocal conditions, such as the number of wells drilled, throughput andwell depth, can be considered in the assessment of the oil spill riskfrom a particular installation.
