Abstract

Pipa milik PT. Energi Listrik Baatam yang mulai beroperasi tahun 2015 merupakan
perusahaan konsorsium antara PT Medco Power Indonesia dan PT Dalle Engineering
Construction Untuk mengalirkan hasil produksinya dari Pemping ORF (Onshore Receiving
Facilities) ke Batam ORF menggunakan pipa bawah laut yang akan ditanam di dasar laut.
Tugas Akhir ini menjelaskan tentang analisa keandalan pipa dalam kondisi terkubur yang
dilakukan terdiri dari analisis gaya - gaya dari pipelines, perhitungan tegangan pipa, serta
keandalan pada pipa yang terbagi menjadi 2 segmen dan 9 section. Berdasarkan hasil
perhitungan tegangan, didapatkan keluaran berupa tegangan ekuivalen von misses. Tegangan
yang diijinkan dari code ASME B31.4 yaitu 90% SMYS didapat nilai sebesar 373.5 MPa,
semua pipa pada setiap section telah memenuhi tegangan yang diijinkan. perhitungan
keandalan pipa didapatkan hasil berupa nilai keandalan pipa yang diperoleh dari hasil
percobaan sebanyak 30000 kali. Hal ini menunjukkan bahwa pipa masih bisa beroperasi
selama design life yaitu selama 25 tahun.
==================================================================================================
Pipeline owned by PT. Electrical Energy Batam which began operations in 2015 is a
consortium between PT Medco Power Indonesia and PT Dalle Engineering Construction To
stream output from Pemping ORF (Onshore Receiving Facilities) to Batam ORF using a
subsea pipeline that will be planted on the seabed. This final project describes the reliability
analysis of pipeline buried under conditions which do consists of the analysis of styles - from
pipelines, pipe stress calculations, as well as the reliability of the pipe that is divided into two
segments and 9 section. Based on the results of stress calculations, obtain the output of the
voltage equivalent von misses. Allowable voltage of ASME B31.4 code that is 90% SMYS
obtained a value of 373.5 MPa, all pipes in each section has met the allowable voltage.
reliability calculation pipe is obtained in the form of pipeline reliability value obtained from
the results of the experiment as much as 30 000 times. This suggests that the pipeline could
still be in operation during the design life is 25 years.
