Reliable operations depend on having the right spare parts available when they are needed—but determining what to hold, where to hold it and in what quantity is a complex engineering challenge. Santos undertook a structured review of spare parts management across its Coal Seam Gas operations to develop a consistent, risk-based approach to inventory optimisation. By improving engineering data, safety stock methodology and governance, the project established a repeatable framework for better inventory decisions. This presentation shares the methodology, outcomes and practical lessons learned to help asset-intensive organisations improve reliability, reduce inventory costs and lower operational risk.
