In this Turbomachinery International Peer Exchange®, moderator Rainer Kurz leads a panel with FS-Elliott’s Shady Saeed, rotating equipment specialist Wael Al Mandarawi, and Saudi Aramco’s Omar Al-Essa. They explain why a centrifugal air compressor’s purchase price is only the opening chapter of its lifecycle cost. Across 13 episodes, they cover criticality assessment, AI-driven monitoring, OEM vs. non-OEM parts, sparing strategy, and the economics of modernizing vs. replacing aging compressors, drawing on real field examples of how operators extend asset life and value.
