Abstract
XYZ Company is a leading company that conducts the business of providing services to oil and gas industries. Services given include drilling, well cementing, logging, and other important services needed by the oil and gas industries’ operations. Maintenance work is essential for company XYZ, to ensure the longevity and effectiveness of tools and equipment when being used while providing various services. Maintenance work done within the workshop includes activities that involve the usage of hazardous materials. Usage of hazardous materials when conducting maintenance work will produce hazardous waste. Hazardous waste and hazardous material possess the risk of failure in polluting the environment and disturb work processes. Therefore, the research combines the method of Fault Tree Analysis (FTA) to assess the root cause of the potential failure with Failure Mode and Effect Analysis (FMEA) to assess the significance of the risk. The result of FTA is in a form of diagram that shows the relationship between the risk of failures and its possible root cause. The first root causes are the most major risk of failures which is then assessed further by using FMEA. FMEA will assess the significance based on the Risk Priority Number (RPN) which is based on the multiplication of Severity (S), Occurrence (O), and Detection (D). Combination of FTA and FMEA will provide a strong risk assessment supported by the visualization of the root cause while assessing the significance of the risk using RPN. The result of the research according to observations, interviews, and secondary data derived from the company shows that the most significant risk of failure for hazardous materials is compressed nitrogen tank storage conditions with a value of 60. Meanwhile for hazardous waste is the hazardous waste collection of overloaded hazardous wastewater with a value of 100. Therefore, the mitigation efforts are suggested based on engineering controls and administrative controls.
