Linking Workplace Safety to Operational Disruptions: A Moderated Mediation Analysis in Commercial Vessels

The purpose of this research was to determine how workplace safety climate affects to what degree employees recognize and report mistakes while on the job. In particular, the authors scrutinize how no-blame error reporting influences the link between workplace safety climate and unplanned maintenance in commercial vessels. They hypothesize that the mediation effect is stronger in newer, more easily-maintained vessels and weaker in older vessels which are more difficult to maintain. Paper and online survey data from 1,169 crewmembers in 86 marine vessels was analyzed using a generalized structural equation modeling approach. The results showed that safety climate promotes no-blame error reporting and hence decreases the frequency of unplanned maintenance. For vessels of a similar age, a high level of safety climate is indirectly correlated to a significantly lower level of unplanned maintenance rate as compared to ships with an average safety climate level. As vessels age, this mediation effect is weakened. This work contributes to an appreciation of how safety is able to facilitate learning in shipping companies. As a practical matter, a high level of safety climate can indirectly reduce unplanned maintenance by up to 32.4% in an average-aged vessel of 15.7 years. The results also indicate that it is essential for managers to encourage no-blame error reporting.
