A Proposed New Laboratory Protocol for Dispersant Effectiveness Testing Adapted for Subsea Dispersant Injection
Daling, Per Snorre; Leirvik, Frode; Krause, Daniel Franklin; Makatounis, Panagiotis Eleftherios; Dunnebier, Dorien Anna Engelbertha; Brandvik, Per Johan (Journal article, 2019-05)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 ... -

JIP oil in ice summary report
Sørstrøm, Stein Erik; Brandvik, Per Johan; Buist, Ian; Dickins, David; Faksness, Liv-Guri; Potter, Steve; Rasmussen, Janne Fritt; Singsaas, Ivar (SINTEF rapport;A14181, Research report, 2010-04-10)The Joint Industry Program on oil spill contingency for Arctic and Ice-covered waters was established in 2006 and completed by the end of 2009. Acknowledging the fact that the Arctic exhibits different environments in the ... -
Large-scale basin testing to simulate realistic oil droplet distributions from subsea release of oil and the effect of subsea dispersant injection
Brandvik, Per Johan; Davies, Emlyn John; Leirvik, Frode; Johansen, Øistein; Belore, Randy (Peer reviewed; Journal article, 2021)Small-scale experiments performed at SINTEF, Norway in 2011–12 led to the development of a modified Weber scaling algorithm. The algorithm predicts initial oil droplet sizes (d50) from a subsea oil and gas blowout. It was ... -
Management of oil spill contamination in the Gulf of Patras caused by an accidental subsea blowout
Makatounis, Panagiotis Eleftherios; Skancke, Jørgen; Florou, Evanthia; Stamou, Anastasios; Brandvik, Per Johan (Journal article; Peer reviewed, 2017-12)A methodology is presented and applied to assess the oil contamination probability in the Gulf of Patras and the environmental impacts on the environmentally sensitive area of Mesolongi – Aitoliko coastal lagoons, and to ... -
Modernisation and updating of SINTEF Oil Weathering Model (OWM} - Extending and recalibration of the Crude Assay (CA) module in SINTEF OWM
Brandvik, Per Johan; Hellstrøm, Kaja Cecilie; Sørheim, Kristin Rist (SINTEF Ocean rapporter;OC2018 A-040, Research report, 2018-05-15)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 ... -
SubSea Dispersant lnjection (SSDI)- a "state of the art" and the need for further documentations
Daling, Per Snorre; Brakstad, Odd Gunnar; Brandvik, Per Johan; Davies, Emlyn J.; Grøsvik, Bjørn Einar; Meier, Sonnich; Nepstad, Raymond; Nordtug, Trond; Vikebø, Frode Bendiksen (SINTEF Ocean reports;2017:00007 A, Research report, 2016-01-08)The aim of this pre-project has been to give a "State-of the art" and describe the R&D challenges and documentation needed in order to perform robust NEBA (Net Environmental Benefit Analysis) where SubSea Dispersant Injection ... -
Subsurface oil releases - Verification of dispersant effectiveness under high pressure
Brandvik, Per Johan; Davies, Emlyn John; Bradly, Cole; Storey, Chris; Leirvik, Frode (SINTEF reports;A27469, Research report, 2016-01-21)The main objective with this project was to study possible pressure dependency of droplet formation in case of a subsea blow out of oil and the effectiveness of subsea dispersant injection (SSDI). The droplet sizes ... -
The sensitivity of the surface oil signature to subsurface dispersant injection and weather conditions
Daae, Ragnhild Lundmark; Skancke, Jørgen; Brandvik, Per Johan; Faksness, Liv Guri (Journal article; Peer reviewed, 2018-02)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 ... -
The use of wide-band transmittance imaging to size and classify suspended particulate matter in seawater
Davies, Emlyn John; Brandvik, Per Johan; Leirvik, Frode; Nepstad, Raymond (Journal article; Peer reviewed, 2017-02-02)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 ...
