Application of a SPAR-H based framework to assess human reliability during emergency response drill for man overboard on ships

Emergency preparedness is of paramount importance in successful emergency responses at sea. Therefore, drills are regularly conducted to maintain acceptable levels preparedness. However, it needs be considered that drill operations themselves include significant risks, and there no evidence these risks appropriately when planning operations. Human error one the main contributors accidents during procedures. The question posed how overall risk, including human errors, an can correctly evaluated. This paper introduces a new hybrid approach based on Standardised Plant Analysis Risk Reliability (SPAR-H) method with fuzzy multiple attributive group decision-making method. provides framework for evaluating specific scenarios associated errors identifies affect performance.

As result, 6.06E-01 was obtained operation. • SPAR-H scenario-oriented approach. proposes which assessed through customised enables evaluate impact characteristics maritime elicits possibility quantitative failure input qualitative experts.
