Another subpart of the risk assessment is to assess the first impact
time of spilt oil. Figs. 8 and 9 show the first impact time of the split oil
in the winter for the coastline and aquaculture farms, respectively. As
shown in Fig. 8, the estimated first impact times for Nanji island and
Daesan harbor are ~4 h and ~6 h, respectively. For aquaculture farms inside
Garorim Bay, the first impact time is in the range of 6 to 11 h, as
shown in Fig. 9.
