Quantification of human error probability towards the gas inerting process on-board crude oil tankers

A new hybrid approach to human error probability quantification–applications in maritime operations

“…However, the two inherently deterministic methods arguably lack capability of dealing with the uncertainties in common performance condition (CPC) configuration (Kim et al, 2006) and different weight assignments (He et al, 2008) to the CPCs in traditional CREAM. Recently, some studies have been conducted for the improvement of CREAM and HEP estimation by means of probabilistic techniques (Kim et al, 2006;Fujita and Hollnagel, 2004), fuzzy approaches (Konstandinidou et Akyuz (2015) constructed a risk-based CREAM model for HEP quantification towards the gas inerting process on-board crude oil tankers and Ribeiro et al (2016) presented a hybrid THERP-CREAM method to analysis the human reliability of Tokai-Mura accidents. Although showing attractiveness in terms of providing solutions to some of the inherent drawbacks of CREAM, such methods have not yet well addressed the incompleteness in subjective data from experts, revealing the need for further studies in the field.…”

Quantitative human error assessment during abandon ship procedures in maritime transportation

“…To overcome this limitation, it is reasonable in HRA probabilistic safety analysis to assume that the maximum human failure probability is 1.0 and the minimum is 0.0001 (He et al, 2008;Akyuz, 2015b). Accordingly, Table 9 shows the SLI and HEP values for each sub-task during an abandon ship procedure.…”

Use of a big data analysis technique for extracting HRA data from event investigation reports based on the Safety-II concept

“…In this regard, it is very important to point out that a large portion of significant events that can impede the safe operation of the complex socio-technical systems was caused by human errors [Pasquale et al, 2015;Stock et al, 2007;El-Ladan andTuran, 2012, Hughes et al, 2015]. For example, Akyuz (2015) and Evans (2011) stressed that human error is one of the main contributors affecting the risk of gas inerting processes and railway systems, respectively. In addition, accoring to recent statistics obtained from the operating experience of NPPs (Nuclear Power Plants), it is revealed that about 80% of significant events are attributable to human errors, which is almost four times compared to the contribution of equipment failures [IAEA, 2014].…”
