Abstract

Risk analysis using RBI on the heat exchanger tube bundle begins with calculating the probability of failure (PoF) and then continues with the calculation of the consequence of failure (CoF). PoF and CoF calculations are based on API 581 Addendum 2020. The type of heat exchanger used is fin fancooler heat exchanger. PoF on fin fan-cooler heat exchanger has several types including PoF before inspection, PoF after inspection, PoF during RBI. PoF is calculated based on the Weibull distribution formula and analyzed based on the Weibull curve. The CoF calculation is only in the financial section. The results of the PoF and CoF calculations will produce a risk value and risk level. The risk will be mapped based on the risk target of the company. Based on the risk value and the level of risk obtained, mitigation recommendations can be estimated. The results of the mitigation recommendations will be analyzed again based on the applicable regulations in Indonesia.
