Abstract

Abstract - In this study the researcher will make a risk analysis using Risk Based Inspection (RBI) method to

determine the risk value of the exportline PPP system towards H-13 tank. The object analyzed is NPS 4" pipe located in the exportline PPP towards H-13 tank. PoF calculations are carried out by using random number generator simulated in the 1st, 2nd, 3rd, 4th, 5th, 10th and 25th year of operation using Monte Carlo method. CoF analysis of the affected area refers to TKI No.C-350 / A2 / EP3200 / 2018-S0 and API RP 581, while financial loss CoF refers to API RP 580. Recommendations for the inspection schedule refer to DNV RP-G101. This study produces various risk level categories depending on each type of leak hole and year of operation. In the first year of operation, the type of small hole has a Low level of risk in analysis of affected area and Low in the analysis of financial losses. In the 4th year, the type of rupture hole has a High level of risk in the analysis of affected area and Medium High in the analysis of financial loss. Risk analysis on NPS 4" shows that once in two-year inspection interval can be recommended by using methods such as visual examination, straight beam ultrasonic, eddy current, flux leakage, radiography, and dimension measurement.
