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 lo...

On the Norwegian continental shelf, there no petroleum activities in ice-covered waters today or planned for the near future. However, future petroleum activities in Arctic waters can take place in areas free of ice most of the year, but with the possibility of occasional drifting sea ice in the win...

The main objective of this study is to develop a new protocol for bench-scale dispersant effectiveness testing adapted for subsea dispersants injection (SSDI). The new approach includes turbulence conditions, dispersant injection techniques and quantification of effectiveness, more representative fo...

Oil weathering predictions have been performed using the Subsea module integrated in the SINTEF Oil Weathering Model (OWM) of a relevant subsea release from a pipeline rupture (batch release) at the Oda oil field. The OSCAR plume model was run to simulate the buoyancy of the rising plume and initial...

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...

This paper presents a compilation of data describing interfacial tension between oil and seawater (IFT(oil-water)) as a function of dispersant dosage. The data are from several earlier laboratory studies simulating subsea oil blowouts to evaluate subsea injection of dispersant (SSDI). Three dispersa...

Benzene, toluene, ethylbenzene, xylenes, naphthalene and n-hexane evaporating from a thin oil film was measured for 30 min in a small-scale test system at 2 and 13 °C and the impact of physicochemical properties on airborne benzene with time after bulk oil release was studied. Linear mixed-effe...

Shipping activities across the Artic are expected to increase with decreasing sea ice cover, thus increasing the risk of oil spills. Heavy Fuel Oil (HFO, a mixture of residual fuel and distillate diluent) is often used as fuel in marine vessels as it is relatively cheaper than e.g. lighter marine fu...
