Abstract

Risk assessment and management (RAM) tools are central to shutdown and turnaround maintenance (STAM), but frequent use does not necessarily demonstrate implementation quality or safety effectiveness. This cross-sectional study analysed respondent-level survey data from 148 STAM professionals in a Nigerian upstream petroleum organisation. Descriptive statistics, Spearman correlations, exploratory factor analysis (EFA), robust multiple regression and Mann-Whitney U incident-group comparisons were applied. JSA (M = 4.53) and toolbox talks (M = 4.35) were used more frequently than HAZOP (M = 2.30) and risk registers (M = 2.27). EFA showed only marginal sampling adequacy (KMO = .610; Bartlett's chi-square(10) = 54.70, p
