Redesain Jalur Pipa Hydrocarbon Gas dari Slug Catcher Menuju Pressure Safety Valve pada Proyek LNG di Sulawesi

Abstract

The demand for energy increases along with economic growth, population, energy prices, and government policies. To address the growing global energy demand, particularly  for LNG, a Joint Operating Body (JOB) of oil and gas company and energy company plans to develop a gas plant facility on the onshore Sulawesi, Indonesia. The main focus of this project is the analysis of the 8”HG-0556-6R pipeline, which is under overstress due to the reaction force from the pressure safety valve. The research methods include calculating the allowable pipe span, stress analysis using software, and redesigning the pipeline according to ASME B31.3 standards. The research finding indicate a 55.6% reduction in flexibility value after redesign, from 0.0074208 to 0.0032925. The highest stress value due to sustain, occasional and expansion loads also decreased significantly, with a decrease ratio of  8.6%, 153.3%, and 80.7%, respectively. As the result, the redesigned pipe effectively reduces the stress value and optimizes the pipe, enhancing its safety.
