Characterization of Low Sulfur Fuel Oils (LSFO) – A new generation of marine fuel oils - OC2020 A-050
This Multi-client project "Characterization of Low Sulfur Fuel Oils (LSFO) - A new generation of marine fuel oils" has been a 1-year project (2019-2020). The project has been funded by MPRI/DFO Canada, ITOPF and the Norwegian Coastal Administration. In order to meet new requirements for lower...
Comparison of artificially weathered Macondo oil with field samples and evidence that weathering does not increase environmental acute toxicity
Establishing a link between composition and toxicity of offshore produced waters using comprehensive analysis techniques – A way forward for discharge monitoring?
Spreading and potential effects of marine fuel oil spills in the Arctic - Arcticfuels
In the ARCTICFUELS project we studied the effects of dissolved fractions of three fuel oils (MGO500, MGO1000 and IFO-LS) on developing cod embryo and larvae. Of the Three fuel oils tested, the MGO1000 displayed the highest toxicity when comparing toxicity based on dilution (% of initial water...
OC2019 A‐054 ‐ KNM "Helge Ingstad" ‐ Miljøundersøkelse - Forvitringsegenskaper, kjemi og toksisitet
OC2018 A-096 - Olje på vann 2018: Analyse av residue, sot og røykgasser fra in situ brenning.
Under årets Olje-pä-vann 0velse (OPV) ble det planlagte programmet for in situ brenning redusert fra 6 til to forsøk på grunn av for mye vind. De to brenneforsøkene ble gjennomført den 13.juni, 2018, på Frigg-feltet i Nordsjøen, med hhv Oseberg 200 °c+ og ULSFO. SINTEF, i samarbeid med Maritime...
PW-Exposed: Produced water fractionation and advanced chemical and toxicological characterization using sensitive life stages of marine fish species
The sensitivity of the surface oil signature to subsurface dispersant injection and weather conditions
Subsea blowouts have the potential to spread oil across large geographical areas, and subsea dispersant injection (SSDI) is a response option targeted at reducing the impact of a blowout, especially reducing persistent surface oil slicks. Modified Weber scaling was used to predict oil droplet sizes...
Biodegradation of oil spill dispersant surfactants in cold seawater
While biodegradation of chemically dispersed oil has been well documented, only a few studies have focused on the degradation of the dispersant compounds themselves. The objective of this study was to determine the biodegradation of dispersant surfactants in cold seawater, relevant for deep sea or...
