Abstract
The piping system is a system used for fluid transportation from one place to another so that the production process can take place. It is necessary to analyze the piping system to find out whether there is an overstress that makes the piping system unsafe. Where the age of the piping system is long enough, it is necessary to recalculate the value of the stress that occurs in the piping system. This research was conducted with a field survey method to collect data on the piping system which was then analyzed using the CAESAR II 2019 software. The results obtained show that the highest stress is at node 100 with 5 load cases. In loadcase 2 the stres ratio reaches 97.4% with a stress value of 134328.5 kPa, loadcase 4 has a stress ratio of 96.9% with a stress value of 133645.4 kPa, loadcase 6 has a stress ratio of 97.4% with a stress value of 134328.6 kPa, loadcase 7 97.4% stress ratio with a stress value of 134328.5 kPa, loadcase 8 stress ratio 96.9 with a stress value of 133645.4 kPa. The stress value is compared with the permit stress limit value based on the ASME B31.3 standard, namely 137892 kPa. After the modification, there was a decrease in the stress at node 100 at loadcase 2 to 7220.7 kPa with a ratio of 5.2%, at loadcase 4 to 6537.5 kPa with a ratio of 4.7%, at loadcase 6 to 7220.6 kPa with a ratio of 5,2%, in loadcase 7 it became 4059.2 kPa with a ratio of 2.9%, at loadcase 8 it became 3376.1 kPa with a ratio of 2.4%. The results show that there are no overstrees in the oil piping system from the well to the well manifold. These results can be taken into consideration so that the piping system is safer in operation.
