Oil and gas exploration has shifted to deep and ultra-deep waters, requiring Floating Production Storage and Offloading (FPSO) facilities due to limited pipeline infrastructure. This study aimed to determine the primary cause of the 2021 Intermediate Pressure Compressor (IPC) failure. Turbomachinery data from 2019 to 2021 was analyzed to identify the dominant parameter leading to compressor fouling. The parameters examined were IPC Anti-Surge Valve (ASV) (%), Total Flow (FT) (mmH2O), Mass Flow Rate (FI) (kg/hr), and Frequency (FQI) ((MMscfe/d). SPSS analysis using Binary Logistic Regression (BLR), Pearson Correlation (PC), and Linear Regression (LR) showed Total Flow 2450 (FT) as the most significant parameter across methods. Binary Logistic Regression proved to be a reasonable technique for analyzing turbomachinery monitoring data. © 2024 Author(s).
