Abstract This report presents a review of methods used for the modelling of subsea gas releases and assesses the implications of using the modelling within a risk assessment. While simple empirical approximations tend to be used in risk assessment, computer modelling based on computational fluid dynamics (CFD) has been used in a research context. Lack of full-scale data has meant that the models have not been validated for high release rates common for blowouts or the rupture of subsea pipelines. In general, the assumptions commonly used in modelling the effects of subsea gas releases lead to conservative estimates of risk.
