Fault Tree Analysis (FTA) of Crude Distillation Unit Failure due to External Factors

This template is a Fault Tree Analysis (FTA) for a crude distillation unit (CDU). It focuses on CDU failure due to external factors. The primary causes identified are earthquakes, leading to equipment displacement and structural damage, and loss of electrical power, resulting in shutdown of CDU and loss of control systems. This diagram is crucial for understanding the potential risks and implementing preventive measures in CDU operations.
