The recommendations presented in this report are intended to provide a logical sequence of building blocks that can be used to conduct the assessment in discrete steps so that early decisions can be made about the most important safety improvements and risk reduction options can be considered in priority order. This approach will allow for an efficient and focused study.

Large commercial vessels engage in the substantial and growing maritime trade between northwestern North America and northern Asia traveling the North Pacific Great Circle Route, which traverses the Aleutian Islands. About 4,500 ships transit Unimak Pass annually, averaging 12 per day, and a similar number travel just south of the Aleutians annually as well.

These and other accident and spill data are valuable input for the risk assessment process. In addition, data for the past 20 years on response to spills in the Aleutians have shown that almost no oil has been recovered as a result of attempts made by the responsible parties or government agencies and that in many cases weather and other conditions have prevented any response at all.

While this Emergency Towing System (ETS) represents an important step forward in improving shipping safety in Dutch Harbor, its coverage is primarily local, and other areas in the Aleutians remain vulnerable.

The committee recommends that a structured risk assessment be performed with two major phases -- a Phase A Preliminary Risk Assessment and a Phase B Focused Risk Assessment. This process would include a specific, stepped approach to collecting and categorizing available data; development of a logical sequence of events defining key scenarios; and use of a risk matrix for an initial qualitative evaluation of risk levels.

Recognizing the importance of stakeholder involvement to the success of the risk assessment, the committee suggests that the Advisory Panel represent all major Aleutian Islands stakeholders, who would provide relevant local knowledge and expertise to the contractors. The panel should review and comment on the framing of the study and its conduct at key stages and help identify and provide input on the risk reduction measures to be evaluated.

Thus, the framework proposed in this report is structured to ensure effective implementation of the most cost-effective risk reduction measures by establishing Phase B as a detailed risk management project. Interim Actions to Enhance the Assessment During its review of existing data, the definition of the problem, and the current state of safety in the system, the committee identified interim actions that would help ensure a successful risk assessment, in particular by providing data to build a better foundation for the assessment process.

The committee further recommends that USCG be ready and available to investigate the possible structure and costs of a Vessel Traffic Information System within and near Unimak Pass and Dutch Harbor, with the expectation that the Risk Assessment Management Team and Advisory Panel might request the information thus generated early in the risk assessment process. This action would facilitate the risk assessment and provide needed data for cost–benefit analyses of selected options.
|
From page 150... ...
Finally, throughout this report, the committee emphasizes principles that are key to ensuring a successful outcome. These include keeping the work focused on a clear definition of boundaries and scope, designing the assessment process to incorporate continuous involvement of local stakeholders, and applying a phased approach to set priorities for early action and allocate resources efficiently.
