Abstract
The weathering properties of five different diesel fuels (DMA-quality) and 3 different "new generation" of low Sulphur marine fuels (also called "Hybrid oils") have been investigated in SINTEF Oil Spill Laboratories. These fuel oil products have been tested with respect to weathering behaviour and properties relevant for potential oil spill response operations in Nordic and Arctic temperatures (sea temperature 0-13 °C). The laboratory study and characterization of the different oils included following parameters:
• Physical-chemical properties at different weathering stages
• Emulsifying properties
• Dispersibility (natural and dispersant enhanced)
• Water accommodated fraction (WAF) and toxicity
• Ignitability (potential for in-situ burning)
The main findings from this laboratory study will be presented.
The study has been funded and performed in cooperation with the Norwegian Coastal Administration (NCA). The NCA has tested the feasibility of the oils to mechanical response operations in the NCA test facility (see separate abstract from NCA).
