ABSTRACTHow vessel crews perceive safety on board (shipboard safety) is a useful indication for the general safety level. In this study a theoretical model was explored, involving factors that could possibly influence shipboard safety. Based on a survey questionnaire (n = 244), safety climate, shipowner efficiency demands and regulatory activities were investigated as influencing factors. Structural equation modelling gave support to the theoretical model and the findings illustrate that simultaneous involvement of various levels of the maritime system (crews, shipowners, regulators) can be effective for safety improvements. The study indicates that shipboard safety is affected by actions and prioritization by external actors through safety climate. It suggests that the maritime industry will profit from monitoring safety climate as part of the ongoing risk considerations, as a supplement to reactive parameters such as accident statistics. 相似文献

Procedure violations are commonly identified as an essential causal factor in maritime accidents. This also applies to the Norwegian offshore service vessel sector. This illustrates that there is a need to study compliance and non-compliance in a broad context and to explore the factors that affect the propensity to act in accordance with prevailing procedures. The aim of the present study was therefore to examine the antecedents of safety-compliant behaviour among workers on offshore service vessels operating on the Norwegian Continental Shelf. With reference to a survey of 1108 offshore service vessel workers, this was done by analysing the relationship between a set of predictor variables and a self-report measure of safety-compliant behaviour. Using binary logistic regression analysis, the present study revealed that the safety climate and the vessel workers’ age were positively related to safety compliance, whereas job experience and perceived procedure vagueness were negatively related to safety compliance. Theoretical and managerial implications are discussed. In sum, the findings indicate that shipowners, captains and other stakeholders within the offshore service vessel industry should consider a broad multi-factorial approach to increase safety compliance. 相似文献
