potential impacts. Referring to previous studies, we divide sea areas into five
categories: marine conservation areas, fisheries, tourist areas, port and waterway
areas and the general areas. The most sensitive ocean environment for oil spills is
given an index of 1 (marine conservation area), the least sensitive, an index value of
0.1 (port and waterway area). The final composite index (R) of ocean vulnerability
to oil spills formula is presented as follows:

M

=

OP i · ESI j ,

R j (6.13)

i = 1

where, OP are oil spill affecting parameters (i.e. the possibility of each grid being
polluted, the shortest arrival time, and the thickness of the slick, etc.), M is the type
number of oil spill affecting parameters.
