Interfacial tension between oil and seawater as a function of dispersant dosage
Embryonic exposure to produced water can cause cardiac toxicity and deformations in Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) larvae
A Proposed New Laboratory Protocol for Dispersant Effectiveness Testing Adapted for Subsea Dispersant Injection
Observations of Rising Methane Bubbles in Trondheimsfjord and Its Implications to Gas Dissolution
Gas dissolution reduces the release of methane to the atmosphere from subsea sources. Being able to predict and assess the methane flux to the atmosphere requires knowledge on gas dissolution and mass transfer. This can be obtained by studying the size evolution of bubbles rising in water. New dat...
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 th...
Field Measurement of BC Emissions from Rolvsnes Well Test Flare - An empirical measurement of particulate emitted from a well test flare to generate a BC emission factor.
BC (smake particulate) was measured in the emissions from the Rolvsnes well test flare from the 6th - 9th of August 2018. Approximately 90% of the measured particulate matter was in the PM I range (1 micron in diameter and smaller). Smoke particulate this small can stay airborne for considerable tim...
OC2018 A-096 - Olje på vann 2018: Analyse av residue, sot og røykgasser fra in situ brenning.
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 ULSFO. SINTEF, i samarbeid med Maritime R...
Comparison of Meso Scale Subsea gas Release With Multiphase Eulerian-Lagrangian CFD Model
We compare the observed dynamics of subsea starting plumes with multiphase computational fluid dynamics (CFD) simulations. In the event of subsea loss of containment of either natural gas or carbon dioxide it is important to understand how the gas disperses in the ocean column and acends to the su...
Exposure to crude oil micro-droplets causes reduced food uptake in copepods associated with alteration in their metabolic profiles
Acute oil spills and produced water discharges may cause exposure of filter-feeding pelagic organisms to micron-sized dispersed oil droplets. The dissolved oil components are expected to be the main driver for oil dispersion toxicity; however, very few studies have investigated the specific contribu...
