Abstract
Pipeline adalah salah satu aset perusahaan yang merupakan peralatan yang kritis dalam industri migas. Guna mengidentiflkasi tingkat keandalan pipeline terse but, maka diperlukan metode yang terintegrasi dengan kondisi operasional untuk mencapai tujuan yang handal, aman, dan ekonomis sepanjang umur desain. Salah satu solusi yang dapat digunakan adalah Pipeline Integrity Management System (PIMS) yaitu suatu metodologi yang memanfaatkan resiko sebagai metoda dasar untuk merencanakan inspeksi dan strategi pemeliharaan yang komprehensif dan terintegrasi antara metodologi RBI untuk melakukan refurbishment design option, repair/replacement decision support, dengan kondisi operasional sepanjang lama operasi. Metode Risk Based Inspection memakai kombinasi dua parameter, yaitu: kategori kemungkinan kegagalan (Pot) dan kategori konsekuensi kegagalan. Peluang kegagalan didapat dengan menggunakan simulasi Monte Carlo. Kemudian dilakukan perhitungan konsekuensi dan didapatkan tingkat kekritisan pipeline yaitu resiko tinggi (5D), menengah-tinggi (4D), dan menengah (3D). Dengan tingkat resiko tersebut dapat dilakukan metode inspeksi yaitu Visual Testing, Ultrasonic Straight Beam, dan Radiography, dengan frekuensi pemeriksaan 1 tahun sekali (tinggi), 2 tahun sekali (Menengah Tinggi), 2.5 tahun sekali (menengah). Setelah mengetahui tingkat resiko dan metode inspeksi, maka dapat ditentukan langkah mitigasi untuk mengurangi resiko pada pipeline tersebut.

Pipeline is one of the company's assets that are critical equipment in the oil and gas industry. To identify the level of reliability of the pipeline, then needed an integrated methods with operational conditions to achieve a reliable, safe, and economical over the life of the design. One solution that can be used is the Pipeline Integrity Management System (PIMS) a methodology that uses risk as a basic method for planning inspection and a comprehensive maintenance strategy and integrated with RBI methodology for design refurbishment option, repair/replacement decision support, with operational conditions along operation time. Risk Based Inspection method using a combination of two parameters, i.e.: probability of failure (PoF) categories and consequence of failure categories. Probability of failure obtained using Monte Carlo simulation. Then calculate the consequences and we got the level criticality of the pipeline are: high risk (5D), medium-high (4D), and medium (3D). So with the risk level, the inspection methods that can be used, i.e.: Visual testing, Ultrasonic Straight Beam, and Radiography, with frequency once a year (high), once in 2 years (Medium High), and once in 2.5 years (medium). After we know about the risk levels and inspection methods, we can make mitigation steps to reduce the risk of the pipeline.
