Abstract

PT. X sebagai perusahaan minyak: bidang hulu memiliki tugas untuk mencari sumber minyak dan gas serta melak:sanakan pengelolaan operasi pada sektor hulu. Dalam pendistribusian minyak: mentah, dengan menggunakan Pipe trunk line sebagai alat transportasinya. Deteksi kebocoran adalah komponen penting dari manajemen risiko pipa karena memungkinkan operator untuk merespons pada waktunya terhadap kebocoran untuk mencegah eskalasi insiden lebih lanjut. Negative Pressure Wave (NPW) merupakan salah satu teknik yang digunakan dalam pendeteksian kebocoran. Prinsip kerjanya yaitu NPW mengidentifikasi pressure signature dari onset kebocoran dan mendeteksi lokasi tempat asal kebocoran tersebut. Pada perhitungan kecepatan propagasi Negative Pressure Wave dimana dipengaruhi oleh panjang ataujarak antara kedua sensor, serta At atau t2- t1 sebagai waktu dimana sinyal diterima oleh sensor di awal pipa dan sensor di akhir pipa. Maka didapatkan terlebih dahulu nilai At dengan cara meninjau Leak trial yang dilakukan pada titik 15.191 m dari sensor yang berada pada inlet. akurasi sistem pendeteksian kebocoran untuk estimasi titik lokasi kebocoran pada pipa didapatkan akurasi rata-rata sebesar 98,77% atau deviasi sejarak: 137 m dari titik aktual. Untuk kecepatan respon didapatkan absolut error sebesar 633 detik dari batas ideal sensor dalam mendeteksi pressure change. Serta didapatkan rata-rata sensitivitas sistem dalam penentuan kebocoran yaitu sebesar pada inlet sebesar 0,173 bar dan pada Outlet sebesar 0.353 bar. Serta perhitungan titik kebocoran yang dilakukan didapatkan rata-rata kesalahan absolut sebesar 11- meter dari titik lokasi kebocoran aktual.

PT X as an upstream oil company has a job to finding sources of oil and gas as well as managing operations in the upstream sector. In distributing crude oil, it use the Pipe trunk line as a means of transportation. Leak detection is an important component of pipeline risk management as it allows operators to respond in time to Leaks to prevent fUrther escalation of incidents. Negative Pressure Wave (NPW) is one of the techniques used in Leak detection. The working principle is that NPW identifies the pressure signature of the onset of the Leak and detects the location of the origin of the Leak. In the calculation of the Negative Pressure Wave propagation speed which is influenced by the length or distance between the two sensors, and !!..tor t2- tl as the time when the signal is received by the sensor at the beginning of the pipe and the sensor at the end of the pipe. Then the value oft is obtained first by reviewing the Leak trial which was carried out at the point 15, 191 m from the sensor located at the inlet. The accuracy of the Leak Detection System for estimating the location of the Leak in the pipe obtained an average accuracy of 98. 77% or a deviation of 137 mfrom the actual point. For the response speed, an absolute error of 633 seconds is obtained from the ideal limit of the sensor in detecting pressure change. And the average sensitivity of the system in determining Leakage is 0.173 bar at the inlet and 0.353 bar at the Outlet. As well as the calculation of the Leak point, the average absolute error is 11-meters from the point of the actual Leak location.
