Akyuz, Emre; Celik, Erkan; Celik, Metin
This paper aims to conduct a practical application for human reliability assessment during operating procedures of an emergency fire pump on-board ship. A systematic human error prediction is performed for designated tasks during operational procedures of the emergency fire pump since human error can be regarded as one of the major factors contributing accidents at sea. Hence, human reliability performance is evaluated to enhance fire safety management in operational level on-board ship. In the paper, marine-specific error producing conditions are adopted under fuzzy sets environment. To enhance consistency of research and minimise subjectivity during expert's judgement stage, the paper is supported with a dominance factor which is used to adjust the impact level of expert's judgments in the aggregation stage of the methodology. The outcomes of the paper provide valuable contributions to the safety managers and technical superintends to monitor fire safety management and crew reliability performance.

Akyuz, Emre; Celik, Erkan
A Single Point Mooring (SPM) unit is a widely recognised off-shore terminal facility in the marine industry since a considerable amount of liquid cargoes can easily be transferred into huge tankers such as VLCCs or ULCCs. Although the system presents high safety standards, any minor accidents due to human error may cause serious harm to the marine environment, human life and the commodity itself. Therefore, nominated crew on-board the tanker and the unit should be very careful during SPM cargo operations. At this point, human reliability plays a critical role in avoiding potential operational or technical failures. In this context, the aim of this paper is to perform a comprehensive human reliability assessment during cargo operations of an SPM unit to enhance maritime safety in off-shore units. The paper prompts a methodological extension of human error assessment and reduction technique (HEART) by incorporating interval type-2 fuzzy sets which overcome more of the uncertainty of experts' judgement and expression in decision-making. The proposed approach not only provides theoretical insight but practical contribution to human reliability assessment in the marine and off-shore industries. (C) 2016 Elsevier Ltd.
