Analisis Tegangan Pada Sistem Perpipaan Yang Terhubung Dengan Kompresor Akibat Penurunan Tekanan Gas Supply

Abstract

This study discusses stress analysis on a piping system connected to a compressor due to a reduction in gas supply pressure at the Suban Field, South Sumatra. The decrease in reservoir pressure leads to increased operating temperatures, which triggers higher stress, particularly in thermal expansion loads. The study was conducted using simulation-based approaches with stress analysis software in accordance with ASME B31.3 standards to calculate sustain, occasional, and thermal expansion stresses, as well as DNV-RP-D101 standards for natural frequency analysis. The results show that under the revamping condition, overstress occurs in thermal expansion loads reaching up to 112.3% of the allowable stress. A recommended support configuration is proposed to reduce excessive stress, while natural frequency values are evaluated to avoid resonance. Support design recommendations are provided by this research to guarantee the pipe system operates safely.
