Numerical modelling of (thin) oil films - Improved behaviour and life time of thin films in the OSCAR model
MetadataVis full innførsel
The PETRO MAKS project "Formation and behaviour of thin oil films and evaluation of response methods including HSE", in the following short "Thin oil films" has the objective to achieve new knowledge more efficient and safe oil spill response operations for releases of condensates and light crude oils that may lead to thin oil films on the sea surface. Main objectives are: 1. lncreased understanding of the formation and behaviour of thin oil films . 2. Assessment of the potential human exposure to volatile compounds 3. Refined processes in oil trajectory models in order to give more reliable predictions of the life time and behaviour of thin oil films and to assess the efficacy of response options. This report addresses objective 3. and summarizes the results of three pre-studies on important processes for modelling of (thin) surface oil. We discuss model improvements and conclude with a proposal for concrete changes in the OSCAR model to better address behaviour and lifetime of thin films in the model.
