Abstract
A standardized bench-scale and meso-scale flume testing weathering study has been conducted on Lille Prinsen crude oil at 13 °C. The dispersibility testing on Lille Prinsen was included to estimate the viscosity limits and time window for dispersant use. The laboratory data were used as input to the SINTEF Oil Weathering Model (OWM) for weathering predictions from a surface release of Lille Prinsen at sea at 5 and 15°C. The weathering properties of Lille Prinsen are also discussed in relation to oil spill response.
