Abstract

In recent years, the necessity of risk assessment is rising in various study fields and in the industry. It is the same in the maritime field. The environmental risk assessment is especially important because the damage for marine environment is serious once the accident of the oil tanker occurs. However the environmental risk assessment is more complex than the safety risk assessment because many things must be considered. The study of the method for assessing the pollution by oil spill from tankers has st arted in IMO, the volume of spilled oil was adopted as its basic index. On the other hand, Inclusive Impact Index (Triple I) has been proposed by the IMPACT Research Committee in The Japan Society of Naval Architects and Ocean Engineers. Triple-I is defined and calculated based on the ecological footprint, ecological risk, human risk, cost, and benefit. By using this index, we can objectively discuss the societal importance of the risk control option from both environmental and economical viewpoints. In this paper we try to apply Triple-I to the environmental risk assessment in the maritime field, and evaluate the risk of the oil tanker and disuss whether Triple-I can be used for the cost effectiveness assessment.
