Abstract
The 12th Oil Spill ldentification Round Robin test (RR2017 ) within the Bonn Agreement Oil Spill ldentification Network of Experts (OSINET ) has been organized by Rijkswaterstaat, Netherlands. This year's case consisted of two spill samples and three source samples in addition to four samples from ln-situ-burning (ISB) from lighter refined products. The samples have been prepared by SINTEF. A large mysterious oil slick was observed drifting in the Norwegian Sea in the morning and it was assumed that this was an illegal spill done during the night. Same of the oil slick was collected in a fire proof boom and ignited, but parts of the slick were too thin to be ignited. Two samples of the slick were collected, one that was assumed to be a bumed residue and one non-bumed oil. Questions for the RR2017; Which of the spill samples is bumed, and compare the residue from the in situ burning (ISB) with the three suspected sources. Are there any differences that can be explained by ISB in addition to the weathering processes? SINTEF has followed the provided checklist for the RR2017. Conclusion: Spill A and Bare from the same source. Spill B is the burned residue. Spill versus Source A: Non-match Spill versus Source B: Positive match Spill versus Source C: Non-match
