A subsea release of gas poses a risk to humans and assets at the surface. Assessing this risk requires knowledge on how much gas reaches the surface and how it is distributed at the surface. This can be estimated by various modelling techniques, e.g. CFD. Reported surfacing flux can then be fed into a CFD model for atmospheric dispersion calculations. This paper briefly discusses how the surface flux can be calculated by CFD, but primarily focuses on the surfacing characteristics and discusses how the surface flux can be reported and issues related to this
