Sea-Operational Profile for Structural Reliability Assessments

This project describes a methodology for establishing operational profiles of ships that are suitable for structural reliability techniques being developed under other SSC projects. The profiles developed are based on historical analyses of existing ship operations and are composed of combinations of ship heading, sea state, and ship speed, as well as descriptions of the uncertainties associated with each variable. The methodology developed is applicable to existing ship classes, including naval ships, and includes information for both lifetime and short-term (mission-oriented) reliability assessments of both fatigue and ultimate strength. Operational profiles were developed for four ship classes including a fast container ship, a tanker, a tramp steamer, and a small naval combatant. One of the resulting profiles was used to perform a sample reliability assessment of the fast container ship examining both short and long-term effects.
