Abstract

Natural gas is one of the abundant natural resources in Indonesia. Indonesia has significant natural gas reserves and is one of the world's largest natural gas producers and has an important role in the energy industry and other economic sectors. Natural gas is used as a fuel for power generation, industry, transportation and households and also used as raw material for the production of LPG (Liquefied Petroleum Gas). Pertamina, has a central role in the production, distribution and management of LPG. Pertamina supplies LPG to various regions in Indonesia through distribution agents and LPG filling stations throughout the country. PT Pertamina uses the STS method to transfer oil, including LPG (Liquefied Petroleum Gas), from large tankers to small tankers. STS is an effective method for optimizing the distribution and delivery of oil, including LPG, to various regions in Indonesia. By using this method, PT Pertamina can send oil cargo more efficiently and flexibly, especially to areas that are difficult to reach by large tankers. In Ship-to-Ship Transfer activities there is a very high potential for fires and explosions, which can endanger the ship's crew. Therefore, a risk assessment is needed so that it can be seen how big the impact caused by the incident. The hazard identification process can be carried out using the Hazard and Operability BS IEC 61882:2001 method, there is a potential danger such as Jet Fire, Flash Fire and Gas Dispersion. Then the frequency analysis process can be carried out using the FTA and ETA method. The highest value is on Flash Fire with value of 7,31E-04, at a diameter of 10-50 mm. Analysis of the consequences of fire modeling using Shell FRED software with the result that Jet Fire is a potential hazard that has the greatest consequences. After that, it will be plotted on the F-N curve as a representation of risk and the results show that the level of risk for each potential is in the "Acceptable" and "ALARP" conditions so that mitigation measures are not necessary.

Gas alam merupakan salah satu sumber daya alam yang melimpah di Indonesia. Indonesia memiliki cadangan gas alam yang signifikan dan merupakan salah satu produsen gas alam terbesar di dunia serta memiliki peran penting dalam industri energi dan sektor ekonomi lainnya. Gas alam digunakan sebagai bahan bakar pembangkit listrik, industri, transportasi dan rumah tangga serta digunakan sebagai bahan baku produksi LPG (Liquefied Petroleum Gas). Pertamina, memiliki peran sentral dalam produksi, distribusi dan pengelolaan LPG. Pertamina memasok LPG ke berbagai wilayah di Indonesia melalui agen distribusi dan SPBU di seluruh tanah air. PT Pertamina menggunakan metode STS untuk mentransfer minyak, termasuk LPG (Liquefied Petroleum Gas), dari kapal tanker besar ke kapal tanker kecil. STS merupakan metode yang efektif untuk mengoptimalkan distribusi dan pengiriman minyak, termasuk LPG, ke berbagai daerah di Indonesia. Dengan cara tersebut, PT Pertamina dapat mengirimkan kargo minyak dengan lebih efisien dan fleksibel, terutama ke daerah yang sulit dijangkau oleh kapal tanker besar. Dalam kegiatan Ship to Ship Transfer terdapat potensi kebakaran dan ledakan yang sangat tinggi, yang dapat membahayakan awak kapal. Oleh karena itu diperlukan penilaian risiko agar dapat diketahui seberapa besar dampak yang ditimbulkan dari kejadian tersebut. Proses identifikasi bahaya dapat dilakukan dengan menggunakan metode Hazard and Operability BS IEC 61882:2001, terdapat potensi bahaya seperti Jet Fire, Flash Fire dan Gas Dispersion. Kemudian proses analisis frekuensi dapat dilakukan dengan menggunakan metode FTA dan ETA. Nilai tertinggi pada Flash Fire dengan nilai 7,31E-04, pada diameter 10-50 mm. Analisis konsekuensi pemodelan kebakaran menggunakan software Shell FRED dengan hasil bahwa Jet Fire merupakan potensi bahaya yang memiliki konsekuensi terbesar. Setelah itu akan diplot pada kurva F-N sebagai representasi risiko dan hasilnya menunjukkan bahwa tingkat risiko masing-masing potensi berada pada kondisi “Acceptable” dan “ALARP” sehingga tidak diperlukan tindakan mitigasi.
