Abstract
A study of the weathering properties of Veslefrikk crude oil has been performed at 5°C and 13°C in small-scale laboratory testing. The data are used as input to SINTEF Oil Weathering Modell (OWM) to predict the behaviour of Veslefrikk in a spill situation at sea. The weathering properties are discussed related to oil spill response; mechanical recovery and chemical dispersibility .
