ABSTRAK Project EPC-1 Banyu Urip merupakan suatu proyek yang memiliki jaringan sistem perpipaan. Mengingat resiko yang ada disekitar jaringan pipa flowline perlu adanya suatu pengamatan pada jaringan pipa tersebut untuk mengurangi resiko kegagalan pada pipa. Resiko kegagalan pada pipa flowline yang salah satunya di akibatkan adanya beban thermal. Dari permasalahan diatas akibat beban ini terdapat bahwa material pipa mengalami kelelahan material, maka diperlukannya perhitungan tegangan juga analisa fatigue terhadap pipa. Hasil yang didapatkan dari analisa perhitungan thermal load dapat diketahui nilai siklus yang mengakibatkan fatigue. Nilai maksimum pada perhitungan manual expansion stress dan developed moment (M) diketahui sebesar 18684.12 psi dan 3476.25 in.lb. sedangkan hasil dari pemodelan pada software diketahui nilai tertinggi expansion stress sebesar 12687.65 psi. Dari analisa menggunakan S-N curve, dapat diketahui bahwa jumlah siklus yang terjadi akibat adanya thermal load dan sustained load sebesar 3 x 10 6 . Siklus Thermal Load yang terjadi masih jauh dibawah nilai endurance limit. Kata Kunci: Piping stress, thermal stress, fatigue analysis, thermal load, occasional load. ABSTRACK Project EPC-1 Banyu Urip is a project that has a network of piping systems. Given the risks that exist around the flowline pipe network needs an observation on the pipeline to reduce the risk of failure in the pipeline. The risk of failure in the pipe flowline that one of them causes the thermal load. From the above problems are due to this load that the material of the pipe material experience fatigue, stress calculations also the need for fatigue analysis of the pipeline. The results obtained from the analysis of thermal load calculations can be seen the value of the cycle resulting in fatigue. The maximum value on manual calculations and developed expansion stress moment (M) is known at 18684.12 and 3476.25 psi in.lb. whereas the results of modeling in software known to the highest value of 12687.65 psi stress expansion. From the analysis using SN curve, it can be seen that the number of cycles that occur due to the thermal load and sustained load of 3 x 10 6 . Cycle Thermal Load happens is still far below the endurance limit value. Keywords: Piping stress, thermal stress, fatigue analysis, thermal load, occasional load.
