Abstract

The reliability of multistage centrifugal pumps, particularly API 610 BB3 types, is critical in water injection systems commonly used in oil and gas operations. This study aims to identify and analyze the dominant failure modes in sleeve bearings used in water injection pump applications, considering comprehensively existing design, operational, and maintenance aspects. The investigation covers analysis using not only equipment condition data (vibration, temperature, oil analysis) but also material examinations, such as optical microscopy, SEM (Scanning Electron Microscope), and EDS (Energy Dispersive Spectroscopy). The results indicate that the root cause of the sleeve bearing failure is lubrication failure, which is attributed to several contributing factors, including improper ISO Code settings for oil analysis and inadequate bearing temperature protection settings. Low-effort and high-impact improvements are proposed, including changing the lube oil type from mineral-based to synthetic-based, using lube oil with higher viscosity, adjusting the ISO Code for oil analysis, and modifying the bearing temperature protection settings. The results of this study are expected to provide a deeper understanding of the sleeve bearing failure mechanism and its implications for equipment reliability, serving as the basis for developing more effective mitigation strategies.

Abstract

Multistage centrifugal pumps are the critical equipment in the water injection system in oil and gas processing facilities but often fail due to abrasive and corrosive fluids. This research utilized the Computational Fluid Dynamics (CFD) approach to analyze the effect of sand particle size, produced water characteristics, and cavitation on the performance of three-stages API 610 BB3 water injection pumps. CFD simulations were performed by varying the sand particle size (10 μm, 100 μm, 100 μm) and produced water characteristics from three locations. The standard k-ε turbulence model and the Eulerian granular flow approach were utilized to model the multiphase flow. The results showed a decrease in pump efficiency of up to 10.39% dan head of up to 19.08% in 1000 μm particles. Analysis of the corrosion rate based on water characteristics showed the highest value of 0.198 mm/year at the location with the highest chloride content and conductivity. Cavitation zones were identified around the leading edge of the impeller at each stage. This study provides an in-depth understanding of the failure mechanisms of the water injection pumps. It can form the basis for developing effective mitigation strategies, such as design improvement, material selection and overhaul program.
