Abstract

This project looks deeply at the integration of human and equipment reliability in hydrogen bunkering operations, focusing on human corrective response actions (HCRAs) to unwanted events in the process. Human responses are also actions shaped by human performance thereby not totally devoid of human error. The possibility of the occurrence of accidents even when both personnel and equipment are reliable draws great attention to examine human responses to occurrences in the bunkering process of hydrogen. The Cognitive Reliability and Error Analysis Method (CREAM) is adopted alongside equipment reliability data from the maritime industry to assess the connection between system performance and human decision-making in the bunkering operation process. The findings show that enhanced equipment reliability significantly improves human corrective responses, leading to great operational efficiency. This study proposes an integrated reliability framework to optimize hydrogen bunkering procedures vis-à-vis an enhanced safety response, providing recommendations for improving safety regulations, and necessitate operator training, equipment management, and risk mitigation approaches. By ensuring industrial compliance and enhancing overall reliability in ship propulsion, these insights contribute to the use of hydrogen as an alternative fuel in the maritime sector for ship propulsion.
