RISK ASSESSMENT OF OFFSHORE PIPELINE OWNED BY PT.TRANS PACIFIC PETROCHEMICAL INDOTAMA PT.TPPI TUBAN DUE TO FREE SPAN USING RISK BASED INSPECTION RBI METHOD

ANALISA RISIKO PADA OFFSHORE PIPELINE MILIK PT. TRANS PACIFIC PETROCHEMICAL INDOTAMA PT. TPPI TUBAN AKIBAT FREE SPAN DENGAN MENGGUNAKAN METODE RISK BASED INSPECTION RBI

ABSTRAK

Pada tugas akhir ini dibahas analisa resiko free span dengan moda kegagalan untuk osilasi In-flow PSL dan Osilasi Cross-flow PSLC. Pipeline 36 milik PT. Trans Pacific Petrochemical Indotama TPPI Tuban telah mengalami span sepanjang 29 meter. Dikarenakan adanya beban lingkungan seperti beban gelombang arusdll. Ada kemungkinan free span akan semakin bertambah panjang dan menyebabkan kegagalan struktur. Oleh karena itu perlu diadakan suatu inspeksi dengan berbasis keandalan. Metode Risk Based Inspection menggunakan kombinasi dua parameter yaitu kemungkinan kegagalan dan konsekuensi kegagalan. Probabilitas kegagalan didapatkan dengan menggunakan simulasi Monte Carlo dan konsekuensi kegagalan didapatkan dengan metode semi kuantitatif Risk Based Inspection RBI sehingga bisa diketahui risiko dari suatu segmen pipeline dengan kategori konsekuensi safety environment economy dan property. Dari hasil simulasi maka diperoleh peluang kegagalan PoF untuk Osilasi in-flow PSL1 0.0076 in-flow PSL2 0.0026 Osilasi cross-flow PSCL1 5.21 x 10-5 dan Osilasi cross-flow PSCL2 2.1 x 10-5. Dengan mengacu pada API RBI 581 maka diperoleh tingkat resiko untuk jenis in-flow PSL1 PSL2 dengan kategori konsekuensi safety environment economy resiko medium 3A dan medium 3B untuk kategori Property in-flow PSL2 resiko medium 3B dan cross-flow PSCL1 PSCL2 dengan kategori konsekuensi safety environment economy medium 3A dan medium 3B untuk kategori Property. Berdasarkan tingkat resiko tersebut maka metode inspeksi yang tepat adalah dengan Clamp-on supports untuk frekuensi inspeksi 2 tahun sekali menengah.


ABSTRACT

In this final project risk analysis discussed free span with a mode of failure for oscillations In-flow PSL and the oscillations of Cross-flow PSLC. Pipeline 36 belongs to PT Trans Pacific Petrochemical Indotama TPPI Tuban has experienced throughout the span of 29 meters. Due to the presence of environmental burden like the weight of the waves currents danll. There is the possibility of free will span growing long and cause failure of the structure. Therefore it should be held an inspection-based reliability. Method of Risk Based Inspection using a combination of two parameters namely the possibility of failure and the consequences of failure. The probability of failure is obtained by using Monte Carlo simulation and the consequences of failure is obtained with the method of semi quantitative Risk Based Inspection RBI so that it can be known risks of a segment of pipeline with category safety consequencesenvironment economy and property.From the results of the simulation then retrieved the odds of failure PoF to Oscillation in-flow PSL 0.0076 inflow PSL2 0.0026 Oscillation of cross-flow PSCL 5.21 x 10-5 and Oscillations of cross-flow PSCL2 1.3 x 10-5. With reference to the API RBI 581 obtained level of risk for different types of in-flow PSL1 PSL2 with category safety consequences environment economy medium risk 3A and medium 3B for the category Property in-flow PSL2 medium risk 3B and cross-flow PSCL1 PSCL2 with category safety consequences environment economy medium 3A and medium 3B for the categories Property. Based on the level of risk then the proper inspection method is with a Clamp-on supports for the frequency of inspection of once every two years intermediate.
