Effectively addressing safety, security and cyber-security challenges is quintessential for progressing the development of next generation maritime autonomous shipping. This study aims at developing a novel hybrid, semi-structured process for the hazardous scenarios identification and ranking. This method integrates the operational and functional hazard identification approaches, whilst considering the safety, security and cybersecurity hazards. This method is applied to comprehensively assess the safety of an autonomous inland waterways ship at a preliminary design phase. The hazardous scenarios are identified and ranked by a number of experts participating in a series of sessions. The identified hazards risk is estimated considering the frequency and severity indices, whereas their uncertainty is estimated by employing the standard deviations in these two indices among the experts ranking results. Epistemic uncertainty is also considered during ranking. Risk control measures are proposed to de-risk the critical hazards. The results reveal that the most critical hazards from the safety, security and cybersecurity perspectives pertain to the situation awareness, remote control and propulsion functions. Based on the derived results, design enhancements along with high-level testing scenarios for the investigated autonomous ship are also proposed.

有效应对安全、安保和网络安全挑战对于推进下一代海上自主航运的发展至关重要。本研究旨在开发一种用于危险场景识别和排序的新型混合半结构化过程。该方法集成了操作和功能危害识别方法，同时考虑了安全、安保和网络安全危害。该方法用于在初步设计阶段对自主内河船舶的安全性进行综合评估。危险情景由参加一系列会议的许多专家确定和排名。考虑到频率和严重性指数来估计已识别的危害风险，而他们的不确定性是通过在专家排名结果中使用这两个指标的标准差来估计的。在排序过程中还考虑了认知不确定性。提出风险控制措施，以降低关键危害的风险。结果表明，从安全、安保和网络安全的角度来看，最严重的危险与态势感知、远程控制和推进功能有关。根据推导出的结果，还提出了对所研究的自主船舶的设计改进和高级测试场景。安全和网络安全观点涉及态势感知、远程控制和推进功能。根据推导出的结果，还提出了对所研究的自主船舶的设计改进和高级测试场景。安全和网络安全观点涉及态势感知、远程控制和推进功能。根据推导出的结果，还提出了对所研究的自主船舶的设计改进和高级测试场景。
