- Povzetek: Opisujemo nadgradnjo preprostega numeričnega modela za račun emulzifikacije (EMU), zasnovanega na metodi Fingas (2010), s katerim predvidimo čas emulzifikacije in stabilnost emulzije. Vhodni podatki so lastnosti nafte in valovanja na območju razlitja. V modelu uporabljamo empirične metode napovedovanja parametrov valovanja. V izvornem modelu je bila uporabljena zgolj metoda Bretschneider (1952), primerna za napovedi v globoki vodi. V dopolnjenem modelu uporabimo štiri dodatne metode: CEM, Seck – Hong ter metodi SMB za plitvo in globoko vodo ter tri tipe nafte z značilno različnimi lastnostmi. Rezultate (čas do začetka emulzifikacije, čas emulzifikacije in skupni čas emulzifikacije), dobljene po vseh metodah, primerjamo med seboj. Ugotovimo, da je v izbranih razmerah izbira ustreznega empiričnega modela valovanja pomembna pri šibkem vetru in kratkih privetriščih. Za določitev najprimernejše empirične metode parametrizacije valov je potrebna nadaljnja primerjava z meritvami in opazovanji valov.
