Risk Control Analysis of Process Failures in Storage Tank Fabrication Using Fault Tree Analysis (FTA) Method

Abstract

The storage tank fabrication industry plays a crucial role in the energy, chemical, and processing sectors due to its function in storing high-risk substances such as fuels, chemical liquids, and natural gas. Fabrication processes that do not comply with standards can lead to serious failures, including leaks, fires, or explosions, which impact workplace safety, environmental damage, and financial losses. This study aims to analyze and control failure risks in the storage tank fabrication process at PT. Sarana Remaja Mandiri. The Fault Tree Analysis (FTA) method is used to identify cause-and-effect relationships of potential failures, both technical and human-related. The analysis results show that the main causes of failure include design errors, improper material selection, welding defects, and non-compliance with operational procedures. Recommended mitigation efforts include enhanced supervision, workforce training, and the use of more reliable technologies and materials. By applying FTA and appropriate risk control strategies, the company can improve product quality, operational efficiency, and maintain its reputation in the storage tank fabrication industry.
