      Johansen, Øistein; Sørheim, Kristin Rist (SINTEF Ocean rapporter;OC2020 A-058, Research report, 2020-05-28)
      Nedgradering av SINTEF Materialer og Kjemi rapport F13494 datert 2009-12-07. Nedgradering ble bestilt av Equinor ved Hanne Greiff Johnsen i mail datert 2020-05-27. Rapporten er nedgradert av SINTEF Ocean AS, avd. Miljø og ...

    • Drift of submerged oil at sea 

      Johansen, Øistein (IKU rapporter;P 319/1, Report, 1982-10-14)
      The report presents results from a major study concerning dispersion of oil from a drifting slick at sea. The major emphasis is given to a discussion of the mechanisms governing the rate of dissipation of oil from 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 ...

    • Modelling of oil thickness in the presence of an ice edge 

      Nordam, Tor; Litzler, Emma; Skancke, Jørgen; Singsaas, Ivar; Leirvik, Frode; Johansen, Øistein (Journal article; Peer reviewed, 2020-07)
      Oil slick thickness is a key parameter for the behaviour of oil spilled at sea. It influences evaporation and entrainment, viable response options, and the risk to marine life at the surface. Determining this value is ...

    • Numerical modelling of (thin) oil films - Improved behaviour and life time of thin films in the OSCAR model 

      Brönner, Ute; Lewis, Alun; Johansen, Øistein; Nordam, Tor (SINTEF Ocean report;OC2017 A-181, Research report, 2017-09-21)
      The PETRO MAKS project "Formation and behaviour of thin oil films and evaluation of response methods including HSE", in the following short "Thin oil films" has the objective to achieve new knowledge more efficient and ...

    • Spreading of waxy Crude Oils on calm weather 

      Brönner, Ute; Johansen, Øistein; Leirvik, Frode; Nordam, Tor; Sørheim, Kristin Rist (Journal article; Peer reviewed, 2018-04)
      The objective of this paper is to provide a simple extension of the much-used gravity spreading model for oil on calm water to account for the spreading behavior of waxy crude oils in cold waters – including the observed ...
