Risk identification and mitigation are and have been ongoing activities within the Narragansett Bay area. As a step toward standardizing methodology, a formal Ports and Waterways Safety Assessment PAWSA for Narragansett Bay was conducted in Seekonk, Massachusetts, on 7-8 September 2004. The results of that workshop are provided in this report. The PAWSA process is a structured approach for obtaining expert judgments on the level of waterway risk. The process also addresses the effectiveness of possible intervention actions for reducing risk in the waterway. A select group of waterway users stakeholders evaluate risk factors and the effectiveness of various intervention actions. Thus the process is a joint effort involving waterway experts and the agencies entities responsible for implementing selected risk mitigation measures. The PAWSA methodology employs a generic model of waterway risk that was conceptually developed by a National Dialog Group on National Needs for Vessel Traffic Services and then translated into computer algorithms by Potomac Management Group, Inc. In that model, risk is defined as the product of the probability of a casualty and its consequences. Consequently, the model includes variables associated with both the causes and the effects of waterway casualties.
