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...

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...

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...

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...

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...

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...
