Hydrocarbon leaks an ever-present danger – the argument with respect to inevitability
HSE started in 1992 to record and classify dangerous occurrences including hydrocarbon releases. This was adopted as their principal technical integrity measure. In the circa quarter of a century from 1992 to 2015, for example, there were 4656 hydrocarbon releases on average 194 per annum. The latest data available is for 2018 where the number of releases was recorded at 96 per annum, so there has been a trend downwards but this should not be understood to be a significant improvement because the population number of installations in 1992 was larger than the number in 2018 due to installations being abandoned at end of life. In any case, the reality is that over the period 1992 to 2015 there was between 3 to 4 hydrocarbon releases per week and in 2018 there was approaching two hydrocarbon releases per week. This can not be viewed as a significant reduction in risk because hydrocarbon loss into the atmosphere, whether it be minor significant or major, are all classified as dangerous occurrences because of the potential of these incidents.
