摘要：	Sea Operational Profiles have been developed from log data for four ships of different type and function. Six profiles were developed for three commercially operated vessels, and four mission-specific profiles were developed for a U.S. Coast Guard Cutter. Operational profiles were organized into joint profiles distributions of speed vs. wave height (sea state), relative heading vs. wave height (sea state), listing of Marsden Zones traversed by the vessel and the relative time spent in each zone. Three case study examples were completed in this project to demonstrate the reliability-based structural analysis approach using the developed sea operational profiles. Two case studies deal with the design wave approach (short term analysis) and spectral approach (long-term analysis). The third case study deals with the application of the spectral approach for the mission oriented operational profile. Limitations and assumptions inherent in different approaches are documented and discussed
