Risk of Vessel Accidents and Spills in the Aleutian Islands: Designing a Comprehensive Risk Assessment

The risk posed to people and the environment by shipping in the Aleutians is greatly influenced by the region’s unique setting, harsh environment, and difficult operating conditions. Such factors as geography, climate, regulatory regime, population and its cultural base, ecology, and industrial activities all combine to define this special operating environment. Assessing the risk in this environment requires a full understanding of these conditions and factors as they are at present and as they may change over time. This report reviews and evaluates available information on the current system and operating environment for shipping in the Aleutian Islands. It presents the study committee’s proposed design for a comprehensive risk assessment for the evaluation of vessel accidents and spills in the Aleutians and recommendations for an appropriate framework for the conduct of that assessment. These recommendations identify a logical sequence of building blocks that can be used to conduct the assessment in discrete steps so that early decisions can be made regarding the most important safety improvements, and risk mitigation options can be considered in the order of their priority. Chapter 1 provides an introduction to the report. Chapter 2 describes the fundamentals of risk assessment, including the methodology, how the assessment is usually structured and managed, and how the committee used these principals to develop a recommended approach for the Aleutian assessment. Chapter 3 describes the region’s local assets and their vulnerability, its climate, and its maritime infrastructure. Chapter 4 presents available information on vessel traffic, movement of hazardous goods, accidents, and spills in the Aleutians, as well as the regulatory framework for navigation in the region. Chapter 5 presents the committee’s recommended organization of the risk assessment, while Chapter 6 describes the proposed technical approach for conducting the assessment. Finally, Chapter 7 contains the committee’s conclusions and recommendations.
