ANALISIS TEGANGAN PIPA 043-GN-31004 PADA SCRUB COLOUMN VESSEL MENUJU VESSEL COLOUMN PROYEK TANGGUH EXPANSION TRAIN 3 PAPUA

Abstract

In this research will be discussed about the analysis of pipeline system voltage in a tough project on line 043-GN-31004 / T08 where the fluid flowing in the pipe fluctuates at pressure and temperature every day and required a voltage calculation analysis to ensure the pipeline has been installed and pedestal pipe that is placed right in place so that the stress (stress) that occurs does not exceed the maximum limit of voltage limitation set by the code / standard ASME B31.3. The result of stress calculation analysis due to the maximum Sustain load is at node 88 in CAESAR II program 171.999 Kpa and manual calculation is 245527.7 Kpa with calculation deviation of 12.34%. So that the calculation does not exceed the allowed limit code / standard ASME B31.3, and due to fluid fluctuations in terms of pressure and temperature causing the pipe to change erratically every day then at node 88 need to be re-planning by adding more buffer flexible so that it can follow the change of pipe, so it can be concluded that the pipeline system in Tangguh Expansion Train-3 project does not happen overstress and safe to operate.
