Abstract

Pipeline memiliki resiko kegagalan yang perlu diperhitungkan sehingga perlu adanya pemeriksaan yang berbasis keandalan. Metode RBI adalah salah satu jenis metode pengelolaan inspeksi yang didasarkan pada tingkat resiko pengoperasian sebuah peralatan atau unit kerja industri. Metode Risk Based Inspection memakai kombinasi dua parameter, yaitu: kategori kemungkinan kegagalan dan kategori konsekuensi kegagalan. Studi kasus analisa resiko ini pada sistem perpipaan milik PT Javagas Pipeline. Peluang kegagalan didapat dengan menggunakan simulasi Monte Carlo. Kemudian didapatkan hasil bahwa tingkat resiko dengan metode RBI semi-kuantitatif pada sistem perpipaan adalah untuk segmen 1-9 Tinggi (5D), 10-25 Menengah Tinggi (4D), 26-50 Menengah (2D). Berdasarkan peringkat resiko tersebut maka metode pemeriksaan yang efektif adalah dengan Ultrasonic Straight Beam, Radiography, dan Visual Testing untuk frekuensi pemeriksaan 1 tahun sekali (tinggi), 2 tahun sekali (Menengah Tinggi), dan 2.5 tahun sekali (Menengah).

Pipeline have a probability of failure to be considered by inspection method based on risk. RBI Method is a one of inspection method based on risk level of equipments or industrial work unit. Risk Based Inspection (RBI) method use two parameter combination for determining level of risk for industrial equipments are failure possibility and failure consequence. A case study using RBI method of risk determination is done for the pipeline system at PT. Javagas Pipeline. The Probability of failure was then estimated by using Monte Carlo simulation to determine that risk. Semi-quantitative RBI methods was applied for the pipeline segment resulting in the following 1-9 High (5D), 10-25 Medium High (4D), 26-50 Medium (2D). From the risk rank an effective inspection method as Ultrasonic Straight Beam, Radiography, and Visual Testing with frequency every 1 year (High), 2 years (Medium High), and 25 years (Medium) are recommended.
