Abstract

Korosi merupakan penyebab utama terjadinya kegagalan struktur pada pipeline yang dapat berdampak terhadap manusia dan lingkungan. Agar tercapai suatu integritas pipeline maka perlu kerangka sistem manajemen korosi, meliputi perencanaan dan implementasi melalui rekayasa teknik sebagai dasar untuk memperkecil resiko yang akan terjadi. manajemen resiko pipeline penyalur minyak dengan metode API RBI581 merupakan kombinasi parameter peluang kegagalan dan konsekuensai kegagalan. Tahap perencanaan bertujuan mendapatkan matriks resiko. Tahap implementasi menggunakan management plan sebagai kebijakan yang diambil meliputi prosedur inspeksi, sistem deteksi, sistem isolasi dan sistem mitigasi. Analisa semikuantitatif adalah hasil perhitungan peluang kegagalan yang dilakukan dengan menggunakan metode Monte Carlo yaitu dengan nilai sebesar 0,13 dan konskuensi kegagalan yang terjadi ialah luas area yang mengalami dampak dari terjadinya kebocoran yaitu seluas 1970.62 ft2 . Sehingga matriks resiko pipeline penyalur minyak berdiameter 8 inch yang terdapat pada PT. JOB Petrochina ialah masuk kategori medium (2D). berdasarkan tingkat resiko yang dimiliki pipeline tersebut, maka prosedur inspeksi yang sesuai ialah dengan melakukan visual inspection dan ultrasonic testing yang dilakukan dua tahun sekali. Sedangkan sistem deteksi dan isolasi dengan instrumentasi deteksi perubahan tekanan dan sistem shutdown otomatis tanpa operator. Sistem mitigasi dengan fire deluge dan sistem monitor.

Corrosion is a major cause of structural failure in the pipeline that may have an impact on humans and the environment. In order to achieve a pipeline integrity management system it is necessary to frame corrosion, including planning and implementation through engineering techniques as a basis to minimize the risk will occur. channeling oil pipeline risk management with the API method is a combination of parameters RBI581 probability of failure and the consequences of failure. Planning phase aims to obtain a risk matrix. Use management plan implementation phase as the measures taken include inspe ction procedures, detection systems, system isolation and mitigation system. Semiquantitative analysis of probability of failure is the result of the calculation is done using the Monte Carlo method with a value of 0.13, and the consequence of failure that occurs is an area that is experiencing the effects of the leakage area of 1970.62 ft2. Matrix so that the risk of channeling oil pipeline 8 inch diameter on PT. JOB Petrochina is categorized as medium (2D). based on the level of risk that owned the pipeline, then the appropriate inspe ction procedure is to perform a visual inspection and ultrasonic testing are conducted every two years. While the detection and isolation system with pressure change detection instrumentation and automatic shutdown systems without operators. Mitigation system with deluge and fire monitoring systems.
