Engineering Safety Requirements for Maritime Autonomous Surface Systems: Hazard Scenarios, Control Loss, and Recovery in Degraded Operations

This paper presents a scenario-based system safety engineering approach that analyzes 80 publicly documented maritime autonomous surface system scenarios to develop a hazard taxonomy, control-loss pathway model, and specific recovery-oriented safety requirements, demonstrating that safe operation depends more on explicitly defined degraded modes and fallback behaviors than on autonomy levels alone.
