• 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 ...

    • 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 ...
