The oil and gas industry faces increasing operational risk due to long spare-parts lead times, import dependency, logistics disruptions, inventory inefficiencies, and rising sustainability pressure under the global energy transition. These challenges are especially significant in developing industrial regions such as Indonesia, where critical components are often sourced from distant suppliers and maintenance operations are highly sensitive to delay. This study introduces the Green Buffer Stock Hub (GBSH), a proposed industrial support framework developed for resilient and sustainable oil and gas supply chains that integrates strategic regional inventory, reverse engineering, additive manufacturing, and digital logistics coordination to improve logistics stability and operational continuity. A conceptual qualitative methodology was applied using industrial supply chain analysis, comparative operational evaluation, and regional applicability assessment for Indonesia, with potential expansion toward Timor-Leste. The findings suggest that localized industrial support ecosystems can improve emergency responsiveness, reduce supply chain vulnerability, and support sustainability objectives simultaneously. Under energy transition conditions, the framework also supports lower transportation intensity, better inventory efficiency, and adaptability to gradual changes in fossil-fuel demand, within an integrated and scalable industrial support model.
