The aim of this paper is to provide a less time-consuming and user friendly tool to find out the most cost-effective and practical corrective actions after the event by improving the data utilization from earlier studies to address the direct and root causes of the incidents. The paper collected frequent incidents contributors for the most common equipment types in oil and gas industry and the typical timing of the error in the life cycle of the project, and then linked the most frequent accidents' contributors with a direct and root causes. The proposed tool consists of three main steps: 1- Select the equipment type where was the event took place, and identify the most frequent incident contributors of the equipment. 2- Identify the timing of incident errors as per the project life cycle. 3- Drive out the direct and root causes of the event, and prioritize/ implement the corrective action. The tool is demonstrated and tested using the piper alpha tragedy as a case study. The most distinguished feature of the tool is that it identifies incidents contributors and the timing errors as well as gives ideas on their removal. The tool established a framework to get the best use of the past accidents analysis, in order to obtain a proactive corrective actions to prevent incidents recurrence. Additionally, it gives a road map for a better identification of corrective actions that directly address the root causes of the events.
