Spreading and potential effects of marine fuel oil spills in the Arctic - Arcticfuels

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1723113

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 accomm...

Establishing a link between composition and toxicity of offshore produced waters using comprehensive analysis techniques – A way forward for discharge monitoring?

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1713981

Extracts of produced waters from five mature Norwegian Sea oil fields were examined as total organic extracts (TOEs) and after fractionation into operationally-defined ‘polar’ and ‘apolar’ fractions. The TOEs and fractions were examined by gas chromatography (GC), GC-mass spectrometry (GC–MS), two d...

OC2019 A‐054 ‐ KNM "Helge Ingstad" ‐ Miljøundersøkelse - Forvitringsegenskaper, kjemi og toksisitet

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1686805

Flere drivstoffprøver fra havaristen Helge lngstad har blitt analysert mhp fysikalske egenskaper og kjemisk sammensetning: Diesel både fra nødlossing og tatt opp på sjø, samt en helikopter­fuel som var samlet opp på sjøen. I tillegg mottok SINTEF to vannpr...

OC2018 A-096 - Olje på vann 2018: Analyse av residue, sot og røykgasser fra in situ brenning.

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1619183

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...

Toxicity of produced water from offshore oil production in Norway and corresponding polar and apolar fractions

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1585778

Regulation of produced water (PW) discharges on the Norwegian continental shelf is based on a maximum oil-in-water limit of 30 mg L¬1. However, the use of conventional oil quantification methods based on traditional GC is limited when it comes to polar compounds that originate from produced cru...

Biodegradation of oil spill dispersant surfactants in cold seawater

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1578887

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 A...

Should current environmental assessment methods for produced water be revised? The influence of chemical composition on produced water toxicity

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1574780

Produced water (PW) from offshore oil production platforms represents the largest discharge of effluent into the offshore environment and is known to contain a complex mixture of dissolved organic compounds and the residues of added production chemicals. The compounds routinely monitored in PW inclu...

The sensitivity of the surface oil signature to subsurface dispersant injection and weather conditions

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1563106

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 ...
