Abstract

Dengan adanya risiko dan kerugian yang akan ditimbulkan bila terjadi kegagalan pada setiap plant maka seluruh peralatan yang sudah ada perlu dijamin dengan adanya reliability sehingga tidak memberikan dampak baik pada pekerja maupun pada lingkungan. RBI merupakan metode yang dapat dilakukan untuk mengantisipasi risiko dengan perencanaan jadwal I&M (inspeksi dan maintenance), karena tujuan dari RBI adalah untuk mengoptimasi waktu dan tipe inspeksi. Terhitung dari tahun 2004 hingga 2018 insiden yang terjadi 28% melibatkan kebakaran dan ledakan, kemudian 71% penyumbang insiden ialah zat berbahaya yang keluar tanpa di sertai kebakaran maupun ledakan dan 1% disebabkan oleh pekerja yang memasuki area terbatas (confined space) yang mengandung zat berbahaya. Didapatkan hasil dari analisis dengan metode preliminary screening criticality pada pressure vessel V-001, V-002, V-003 dan V-004 memiliki kategori risiko medium risk. Perhitungan lanjutan dengan metode RBI pada pressure vessel didapatkan memiliki level risiko medium risk pada pressure vessel V-001 dan V-002, dan pressure vessel V-003 serta V-004 memiliki level risiko low risk. Strategi inspeksi yang dapat dilakukan antara lain visual inspection, ultrasonic test dan radiography.

With the risk and losses that will be occurred if there is a failure in each plant, all existing equipment needs to be guaranteed with reliability so it does not have an impact both to workers and to environment. RBI is a method that can be used to anticipate risk by planning I&M (inspection and maintenance) schedules, because the purpose of RBI is to optimize time and type of inspection. From 2004 to 2018, 28% of incidents involved fires and explosions, then 71% of the incident contributors were hazardous substances that escaped without fire or explosion and 1% were caused by workers entering confined spaces containing hazardous substances. Analysis obtained from preliminary screening criticality method are pressure vessel V-001, V-002 V-003 and V-004 risk category is medium risk. Advance equation using RBI method on pressure vessels have a risk level of medium risk on pressure vessel V-001,V-002 and V-003 also V-004 pressure vessels have a risk level of low risk. Inspection strategy arranged are visual inspection, ultrasonic test and radiography test.
