Abstract
Minyak dan gas bumi adalah penyumbang terbesar dari kebutuhan energi saat ini. Offshore
pipeline adalah salah satu moda transportasi yang efektif dan efisien dalam melakukan
pendistribusian minyak dan gas untuk kebutuhan energi. Industri minyak dan gas bumi selalu
dihadapkan dengan berbagai risiko, baik dalam skala besar maupun kecil. Dalam menangani risiko
tersebut, maka perlu dilakukan pengelolaan risiko dengan baik agar mengurangi dampak dari
risiko tersebut. Offshore pipeline transmisi Sumatera Jawa merupakan salah satu pipa yang
berfungsi menyalurkan gas dari pulau Sumatera menuju Jawa. Berdasarkan studi lapangan yang
dilakukan, risiko yang terjadi merupakan risiko yang terkait pada kondisi pipa. Untuk melakukan
pengelolaan terhadap risiko yang terjadi maka penelitian ini menggunakan metode Probabilistic
FMEA. Dari hasil analisis risiko yang dilakukan maka didapatkan Risk Priority Number (RPN)
pada lima risiko yaitu general metal loss sebesar 0.00076, mechanical overstress sebesar 0.00083,
impact sebesar 0.00070, over-pressurisation sebesar 0.00066 dan fatigue sebesar 0.00063.
Adapun program perbaikan yang dapat dilakukan untuk masing-masing risiko tersebut adalah
melakukan pemasangan grout bag, anchor buoy dan menggunakan Reliability Centered
Maintenance (RCM) untuk menggantikan corrective maintenance yang selama ini dipakai.

Oil and gas are the largest contributor of energy needs at this time. Offshore pipeline is one of the
modes of effective and efficient transportation in distributing oil and gas for energy needs. The oil
and gas industries are always faced with various risks, both in large or small scale. To solve these
problems, it needs good risk management in order to reduce the effects of such risks. Sumatra-
Java offshore transmission pipeline is one of pipes that serves to distribute gas from Sumatra to
Java. Based on field studies performed, the risk that occurs is a risk which related to the pipe's
condition. To manage the risks that will occur, so this research uses a Probabilistic FMEA method.
From the results of the risk analysis, then Risk Priority Number is obtained in five risks. They are
general metal loss amounted to 0.00076, mechanical overstress amounted to 0.00083, impact
amounted to 0.00070, over-pressurisation amounted to 0.00066 and fatigue amounted to 0.00063.
The improvement program that can be made for each of these risks are doing installation of grout
bag, anchor buoy, and using Reliability Centered Maintenance (RCM) to change the corrective
maintenance that had been used.
