Abstract

Pipeline dikenal sebagai sarana transportasi yang paling aman untuk mendistribusikan fluida baik dalam bentuk liquid maupun gas. Sarna halnya dengan peralatan lain pada umumnya, pipa juga dapat mengalami kegagalan dan memerlukan program inspeksi. Munculnya kegagalan pada pipa akan berdampak pada masyarakat disekitar jalur pipa serta kerusakan dan pencemaran pada lingkungan. Salah satu penyebab utama terjadinya kegagalan pada pipa adalah korosi. Oleh sebab itu, perlu adanya suatu penilaian risiko untuk mengetahui peluang kegagalan, konsekuensi kegagalan, serta tingkat risiko pada sistem perpipaan terutama terhadap korosi . Pipeline risk assessment adalah salah satu metode yang paling baik untuk mengidentifikasi suatu kejadian potensial tidak hanya yang menyebabkan gangguan pada operasional melainkan juga pada kejadian yang berhubungan dengan safety dan masalah lingkungan. Penelitian ini membahas tentang penilaian risiko pada pipa distribusi crude oil dari GS-3 (Gathering Station) sampai NBS (North Booster Station) sepanjang 11.1 km. Penilaian risiko pada penelitian ini menggunakan code API 581 dan dilakukan secara semikuantitatif yang mana perhitungan peluang kegagalan menggunakan metode simulasi Monte Carlo didapatkan hasil sebesar 0.0149 dan konsekuensi kegagalan ialah luas area yang terkena dampak dari tetjadinya kebocoran yaitu seluas 2094.77 ft2 . Sehingga didapatkan hasil tingkat risiko pada pipa crude oil12" dari GS-3 sampai NBS milik PT. X termasuk dalam kategori menengah atau medium

Pipelines are known as the safest means of transportation for distributing fluids, both liquid and gas. Like other equipment in general, pipes can also experience failure and require an inspection program. The occurrence of pipe failure will impact the community around the pipeline as well as damage and pollution to the environment. One of the main causes of pipe failure is corrosion. Therefore, a risk assessment is necessary to determine the probability of failure, the consequences of failure, and the level of risk in the piping system, especially against corrosion. Pipeline risk assessment is one of the best methods to identify a potential event not only causing operational disruption but also incidents related to safety and environmental issues. This study discusses the risk assessment of the crude oil distribution pipeline from GS-3 (Gathering Station) to NBS (North Booster Station) along 11.1 km. The risk assessment in this study uses API 581 code and is carried out semi-quantitatively, where the calculation of the probability of failure using the Monte Carlo simulation method produces a result of 0.0149 and the consequence of failure is the area affected by the leak, which is 2094.77 ft2. So the results obtained are that the risk level of the 12" crude oil pipeline from GS-3 to NBS owned by PT. X is included in the medium category
