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...

The main objective with this study has been to study injection techniques for subsea dispersant injection (SSDI) to recommend techniques relevant for both laboratory studies and operational response equipment. The most significant factor was the injection point of the dispersant in relation to the r...

Objectives The main aim of this study was to assess the biological uptake of benzene and polycyclic aromatic hydrocarbons (PAHs) for subjects exposed to fresh crude oil released at sea. Methods: The study included 22 subjects participating in an ‘oil-on-water’ field trial in the North Sea. Over 2 co...
