Fishbone Diagram Analysis for Assessing Ergonomic Risks in Onshore Oil Rig Operations

Abstract

Oil producers are always keen on ensuring safety standards followed in oil rigs and adheres to it during crude oil extraction. Global economy still relies heavily on petroleum production even though renewable energy sources are playing a vital role. Onshore oil rigs are used to extract crude oil from underneath the earth surface. As the working environment is more challenging and riskier in operations, ergonomic interventions are accepted by most of the companies. Despite the safety culture and large-scale modernization, still the industry shows high ergonomic risks and leads to musculoskeletal disorders to workers. Fishbone diagram analysis is a graphical tool used by many organizations for making diagnoses or taking concrete actions in which, the root cause of the problem is identified. The present study analyses the ergonomic risks associated with onshore oil rigs using fishbone diagram analysis and assess the risk factors based on machine, method, materials, measurement, man and environment. In-addition, the study presents the ergonomic risks in mud mixing operations using fishbone diagram. The study leads to guide the occupational experts to judge the risk levels and to develop risk mitigation plans.
