This study is based on using management tools such as risk management, project management tools and teamwork in Turnaround Maintenance Activities (TMA) in a typical petrochemical and refinery industry in Nigeria, one of the notable oil-producing developing nations. To achieve the broad objective of the study, a structured questionnaire was developed based on three sub-hypotheses on the significance of the management tools under study in TMA in the petrochemical and refinery industry. The respondents consisted of carefully sampled 341 workers at a refining and petrochemical company, ranging from the Maintenance department, Engineering and Technical Services department, Health Services and Environment department, Supply Chain Management department, as well as contractors. Using inferential statistics and Pearson correlation analysis, the sub-hypotheses were analysed. The results of the study showed that the management tools considered have a significant relation with TMA with R-values of 0.617, 0.742, and 0.714 for the relationship of TMA with risk management, project management tools, and teamwork, respectively. Furthermore, the study’s findings showed that most respondents strongly agree that the successful TMA implementation in the petrochemical and refinery industry is dependent on good risk management practices such as risk survey, quantification, mitigation, and leadership collaboration (p-value = 0.01), use of project management tools encompassing decomposition, critical path analysis, visualisation, accountability, and performance matrices (p-value = 0.002), and adequate integration of teamwork to ensure transparency, synchronisation, equity, and collaboration (p-value = 0.002). The study concluded by recommending continuous application of these management tools and many more to ensure effective TMA in the industry.
