In the graduate thesis we described the process of emulsification of spilled oil. Numerical models are
used for simulating the process. We used the EMU model, a simple program for determining the stability
of emulsion and time of the emulsification processes. In the original model only the Bretschneider
method was used for calculating the wave height. Since this method overestimates the wave height, the
original EMU model was modified by adding four other methods for calculating the wave height: Seck
– Hong method, method CEM, and SMB methods for deep and shallow water. We compared the results
of all applied methods for calculating the wave height, emulsification time of Cook Inlet – Granite Point
oil, performed with all methods using different input parameters. The results are presented as tables and
graphs. We concluded that the choice of wind parameterization method is an important factor in
determining the time of the emulsification processes, particularly when simulating spills of light oils.
