MetadataShow full item record
The 11 th Oil Spill ldentification Round Rabin test (RR2016) within the Bonn Agreement Oil Spill ldentification Network of Experts (OSINET) has been organized by Rijkswaterstaat, Netherlands. This year's samples, one spill sample and three source samples, have been prepared by SINTEF. The Spill sample was collected from a buoy in a drifting oil slick in the North sea close to the border between the Norwegian and British sector. There are several suspected sources, both from platforms and passing ships. Three of them are selected for comparison with the Spill sample. Questions to be answered in the RR2016 case: which of the source samples is the source of the Spill sample? And what kind of weathering has taken place? • The Source samples 1 and 2 are most likely refined products • The Source sample 3 is a fresh light paraffinic crude oil • The Spill sample is a paraffinic crude oil • The Spill sample is heavily weathered with a high wax-content due to a mechanical wash out of the liquid components in the oil and the solid wax-components are remaining • The Spill sample is non-match to Source 1 and Source 2. • The Spill sample is a positive match to Source 3.
