Methodology for Risk-Based Technology Applications to Marine System Safety

This paper presents the principles for the application of Risk-Based Technology (RBT) to marine system safety. Reducing risk in marine systems is possible with the use of RBT concepts. Risk-Based Technology is the application of risk analysis methods to some knowledge, process, or system that provides a consistent and rational approach to improved decision making. Risk analysis is the process of evaluating risk through a consistent and structured application of interrelated risk assessment, risk management, and risk communication. Risk-based safety determinations provide consistent and rational answers to the questions: (1) What can go wrong? (2) What is the likelihood it will go wrong? (3) What are the consequences if it does go wrong? An accurate response to these questions in the examination of marine systems can provide useful information to decision makers. The U.S. Coast Guard is taking an active role in the implementation of risk analysis on the national as well as international levels to assist in the development of proactive marine safety criteria. Riskbased safety analysis can play a vital role in the efficient utilization of resources to develop better standards, designs, and reliable and consistent certification and inspection of marine systems.
