Abstract
Pada pembangkit listrik tenaga geothermal, sumber energi yang digunakan berupa
panas bumi dimana dalam proses pengambilan sumber panas yang dibutuhkan oleh
turbin, terdapat risiko terjadi kerusakan equipment yang menyebabkan kegagalan
proses produksi. Kerusakan yang sering terjadi pada pembangkit listrik geothermal
adalah fouling dan korosi yang disebabkan sumber reservoir mengandung zat kimia
tertentu. Untuk mengurangi terjadinya kerusakan equipment dan mengelola risiko
dengan memfokuskan upaya inspeksi pada equipment proses yang memiliki tingkat
risiko tinggi di PLTP Wayang Windu, kabupaten Bandung, analisa risiko dengan
menggunakan proses Risk Based Inspection (RBI) diterapkan pada separator Vessel
VS-80-001 to VS-80-003 dan well pipes pada fasilitas SEGWWL unit 2.
Hasil analisis Probability of Failure (PoF) pada separator Vessel VS-80-001 to VS-
80-003 bernilai 0.0837 (RBI plan date) yang menunjukkan bahwa laju kegagalan
meningkat sebesar 0.0837/tahun. Sedangkan analisis Consequence of Failure (CoF)
menunjukkan bila terjadi kerusakan pada equipment (separator) maka area yang
terpengaruh 652m2. Analisis resiko menunjukkan bahwa hasil probability range
dikategorikan sebagai 5A medium risk. Hasil analisis Probability of Failure (PoF)
pada VS pipeline bernilai 0.019 (RBI plan date) yang menunjukkan bahwa laju
kegagalan meningkat sebesar 0.0019/tahun. Sedangkan analisis Consequence of
Failure (CoF) menunjukkan bila terjadi kerusakan pada equipment (pipeline) maka
area yang terpengaruh 184.8m2. Analisis resiko menunjukkan bahwa untuk
probability range dikategorikan sebagai 4D medium high risk.
=========================================================
Geothermal power plants use hot steam from inside the earth to produce electrical
energy. In the process of retrieving the heat source needed by the turbine, there is a
risk of equipment damage that causes a failure of the production process. Damage
that is common in geothermal power plants, is fouling and corrosion caused by
reservoir sources containing certain chemicals. To reduce the occurrence of
equipment damage and manage risk by focusing inspection efforts on process
equipment that has a high risk level (separator) at the Wayang Windu PLTP,
Bandung district, Risk Based Inspection (RBI) risk analysis is applied. Probability of
Failure (PoF) analysis results are 0.0837 (plan date RBI) which indicates that the
failure rate increased by 0.0837 / year. While the analysis of Consequence of Failure
(CoF) shows that if there is damage to the equipment (separator) then the affected
area is 652m2. The result of risk analysis shows that the probability range results are
categorized as 5A medium risk. While the results of Probability of Failure (PoF)
analysis on VS pipeline are 0.019 (plan date RBI) shows that the failure rate
increases by 0.0019 / year. Tthe analysis of Consequence of Failure (CoF) shows
that if there is damage to the equipment (pipeline), the affected area is 184.8m2. Risk
analysis shows that the probability range for pipeline is categorized as 4D medium
high risk.
