Abstract
Industri minyak dan gas memiliki tingkat risiko proses yang tinggi karena pengoperasian peralatan pada kondisi tekanan dan temperatur tinggi. Salah satu peralatan kritis adalah Gas Turbine Compressor di Saka Indonesia Pangkah Limited (SIPL) yang berpotensi mengalami deviasi proses sehingga dapat memicu compressor surge, overpressure, kebocoran gas mudah terbakar, dan kerusakan mekanis. Penelitian ini dilakukan untuk mengidentifikasi potensi bahaya menggunakan metode Hazard and Operability Study (HAZOP) serta mengevaluasi kecukupan lapisan proteksi melalui metode Layer of Protection Analysis (LOPA). Analisis HAZOP diterapkan pada empat node berdasarkan Piping and Instrumentation Diagram (P&ID) dengan mengevaluasi parameter flowrate, pressure, temperature, compressor speed, dan anti-surge valve. Tingkat risiko ditentukan menggunakan risk matrix berdasarkan penilaian severity dan likelihood. Hasil analisis menunjukkan bahwa dari 26 skenario deviasi yang diidentifikasi, sebanyak 13 skenario (50,00%) termasuk kategori Acceptable, 6 skenario (23,08%) berada pada kategori Torelable, 2 skenario (7,69%) termasuk dalam kategori As Low As Reasonably Practicable, Tidak terdapat skenario (0,00%) yang termasuk kategori Intolerable, dan 5 skenario (19,23%) berada pada kategori Unacceptable. Analisis LOPA terhadap lima skenario prioritas menunjukkan bahwa empat skenario diklasifikasikan sebagai No Requirement (NR), sedangkan satu skenario pada Node 4 memerlukan Safety Integrity Level (SIL) 0. Berdasarkan hasil tersebut, peningkatan keandalan lapisan proteksi direkomendasikan untuk meningkatkan keselamatan proses dan menjaga keandalan operasi.

The oil and gas industry involves high process risks due to the operation of equipment under high-pressure and high-temperature conditions. One of the critical pieces of equipment is the Gas Turbine Compressor at Saka Indonesia Pangkah Limited (SIPL), which is susceptible to process deviations that may lead to compressor surge, overpressure, flammable gas leaks, and mechanical damage. This study was conducted to identify potential process hazards using the Hazard and Operability Study (HAZOP) method and to evaluate the adequacy of existing protection layers using the Layer of Protection Analysis (LOPA) method. The HAZOP analysis was performed on four nodes identified from the Piping and Instrumentation Diagram (P&ID) by evaluating the parameters of flow rate, pressure, temperature, compressor speed, and anti-surge valve operation. Risk levels were determined using a risk matrix based on severity and likelihood assessments. The results identified 26 deviation scenarios, of which 13 scenarios (50.00%) were classified as Acceptable, 6 scenarios (23.08%) as Tolerable, 2 scenarios (7.69%) as As Low As Reasonably Practicable (ALARP), no scenarios (0.00%) as Intolerable, and 5 scenarios (19.23%) as Unacceptable. The LOPA evaluation of five priority scenarios indicated that four scenarios were classified as No Requirement (NR), while one scenario in Node 4 required Safety Integrity Level (SIL) 0. Based on these findings, improving the reliability of the existing protection layers is recommended to enhance process safety and maintain operational reliability.
