<![CDATA[Cleaning of pipelines is necessary to ensure that the pipeline remains in a condition that is suitable for use, does not contain impurities that can affect the product or affect the condition of the pipe. The research objective is to identify the K3 hazards and risk assessment of the pig acceptance process using Hazop’s techniques, as well as identify them. This study used a qualitative observational approach by assessing the 6 Node P&ID diagrams in the pigging process. Assessment using the Hazops table. The results showed that the first node of Pig Barrel 20 "MOL (HMC) identified 2 critical deviations, namely: less pressure and less flow; 5 Causes, and 5 Consequences, 2nd Node Pig Barrel 12 "MOL (Condensate) identified 2 critical deviations, namely: Less Pressure and Less Flow; 6 causes, and 5 consequences, the 3rd node of the Sump Tank (T-2080) identified 3 critical deviations, namely: High level, No pressure of the pump, and More sand; 5 Causes, 6 Consequences, 4th Node Close Drain (V-915) identified only 1 (one) critical deviation, namely: High Level; 3 Causes, 4 Consequences. The 5th node of the First Stage Separator HMC (V-860) identified 4 deviations, namely: High Level, High Pressure, Low Level, Low Pressure; 11 Causes, 15 Consequence, 6th Node First Stage Separator Condensate (D-6250) identified 5 (three) deviations, namely: High Level of Condensate, High Pressure, Low Level of condensate, Low Pressure, High Level of Water; 13 Causes, 19 Consequences. The conclusion in this study is that there are 17 deviations in the pigging work process and there are 5 hazards with low risk, 12 hazards with moderate risk, 4 hazards with high risk.]]>
