Abstract

Ledakan dan kebakaran menjadi salah satu potensi terbesar yang dapat terjadi pada proses offloading. Pada proses transfer hasil produksi dari FPSO ke kapal shuttle tanker, dapat menimbulkan risiko seperti jetfire, gas dispersion, pool fire dan kebocoran tumpahan minyak pada lokasi eksplorasi. Sehingga penting untuk dilakukan penilaian risiko pada proses offloading dari kapal FPSO ke kapal shuttle tanker untuk mengantisipasi kemungkinan bahaya yang akan terjadi pada proses transfer. Oleh karena itu dalam tugas akhir ini akan membahas tentang penilaian risiko potensi kebakaran dan ledakan pada proses offloading di sebuah FPSO. Penelitian ini diawali dengan mengidentifikasi bahaya pada sistem offloading dengan menggunakan metode Hazard Operability (HAZOP) yang kemudian dilanjutkan dengan melakukan analisa frekeuensi dan konsekuensi dengan menggunakan metode Fault Tree Analysis dan Event Tree Analysis. Analisa konsekuensi pada penelitian ini akan menggunakan fire modelling software. Setelah melakukan analisa frekuensi dan konsekuensi maka dilakukan pemetaan risiko dengan F-N Curve sesuai dengan standar UK HSE. Terdapat 3 node dalam analisis kebakaran sistem. Peristiwa yang terjadi adalah kebakaran kolam (pool fire), uap beracun (toxic vapor), dan tumpahan minyak (oil spill). Frekuensi terbesar terdapat pada node 3, dengan frekuensi kebakaran kolam sebesar 3,52 E-05, Toxic Vapour sebesar 2,26 E-03, dan tumpahan minyak sebesar 3,26 E-02. Semua risiko dari setiap skenario kejadian berada pada level ALARP (As Low As Reasonably Practicable)

Explosions and fires are one of the biggest potentials that can occur in the offloading process. In the process of transferring production results from FPSO to shuttle tanker ships, it can cause risks such as jetfire, gas dispersion, pool fire and oil spill leaks at exploration locations. So it is important to carry out a risk assessment in the offloading process from FPSO ships to shuttle tanker ships to anticipate potential hazards that will occur in the transfer process. Therefore, this final project will discuss the risk assessment of potential fires and explosions in the offloading process in an FPSO. This study began by identifying hazards in the offloading system using the Hazard Operability (HAZOP) method which was then continued by conducting a frequency and consequence analysis using the Fault Tree Analysis and Event Tree Analysis methods. The consequence analysis in this study will use fire modeling software. After conducting a frequency and consequence analysis, risk mapping was carried out with the F-N Curve in accordance with UK HSE standards. There are 3 nodes in the system fire analysis. The events that occurred were pool fire, toxic vapor, and oil spill. The highest frequency is at node 3, with a pool fire frequency of 3.52 E-05, Toxic Vapor of 2.26 E-03, and oil spill of 3.26 E-02. All risks from each event scenario are at the ALARP (As Low As Reasonably Practicable) level.
