Abstract
Pipeline dikenal sebagai sarana transportasi yang paling aman untuk mendistribusikan fluida baik dalam bentuk liquid maupun gas. Sama 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 terjadinya kebocoran yaitu seluas 2094.77 ft2. Sehingga didapatkan hasil tingkat risiko pada pipa crude oil 12” dari GS-3 sampai NBS milik PT. X termasuk dalam kategori menengah atau medium.

Pipelines are known as the safest of transportation to distribute fluids in both liquid and gas forms. As other equipment in general, the pipe can also fail and require an inspection program. The emergence of a failure on the pipe will have an impact on the community around the pipeline as well as damage and pollution to the environment. One of the main causes of failure of the pipe is corrosion. Therefore, it is necessary to have a risk assessment 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 for identifying a potential event, not only that causes of operational disruption but also in events related to safety and environmental problems. This study discusses the risk assessment on the crude oil distribution pipeline from GS-3 (Gathering Station) to NBS (North Booster Station) along 11.1 km. Risk assessment in this study uses API 581 code and is conducted semi quantitatively in which the calculation of the probability of failure using the Monte Carlo simulation method is 0.0149 and the consequence of failure is the area affected by leakage which is 2094.77 ft2. So, we get the results of the level of risk in the 12" crude oil pipe from GS-3 to NBS owned by PT. X is included in the medium or medium category.
