Quantification of oil droplets under high pressure laboratory experiments simulating deep water oil releases and subsea dispersants injection (SSDI)
Interfacial tension between oil and seawater as a function of dispersant dosage
Shedding from chemically-treated oil droplets rising in seawater
Combined releases of oil and gas under pressure; the influence of live oil and natural gas on initial oil droplet formation
Subsea dispersants injection (SSDI), effectiveness of different dispersant injection techniques – An experimental approach
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...
Novel Oil Spill Technology-Subsea Mechanical Dispersion & Surface water flushing of thin oil films
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...
Modernisation and updating of SINTEF Oil Weathering Model (OWM} - Extending and recalibration of the Crude Assay (CA) module in SINTEF OWM
SINTEF har siden åttitallet foretatt forvitringsstudier på en rekke oljetyper (både norske og utenlandske). Hovedmålsettingen med disse forvitringsstudiene har vært å predikere oljenes forvitringsegenskaper dvs. hvordan de oppfører seg på sjøen ved et eventuelt oljesøl (fordamping, emulgering...
The use of wide-band transmittance imaging to size and classify suspended particulate matter in seawater
An in situ particle imaging system for measurement of high concentrations of suspended particles ranging from 30 μm to several mm in diameter, is presented. The system obtains quasi-silhouettes of particles suspended within an open-path sample volume of up to 5 cm in length. Benchmarking against...
