Ha Long Bay, Nghi Son port, Da Nang port, Dung Quat port and Dong Nai, Sai Gon estuaries are very sensitive areas to the oil spill. Many economic activities, such as port development, maritime transport, oil and gas exploitation/exploration, fisheries, and tourism, concentrate in these areas, that increaes the likelihood of oil spill. Thus, the maps showing the sensitivity of the shoreline to oil spill are required for the coastal managers in oil-spill response. This paper reports the development of the oil spill Environmental Sensitivity Index (ESI) maps for the above listed areas.
