The aim of this document is to provide practical guidance on a selection of topics for qualifying and procuring additively manufactured parts in the oil and gas sector. It offers structured tools and guidance to help technical, quality, and procurement professionals interpret existing standards more consistently. By addressing key aspects such as part criticality, inspection planning, material documentation, and audit execution, this document promotes traceability, strengthens supply chain resilience, and supports future integration with Digital Inventory (DI) systems. The oil and gas industry is undergoing a transformation in how spare parts and parts are sourced, qualified, and manufactured. Traditional supply chain models—relying on centralized manufacturing hubs and physical inventory—have proven vulnerable to global disruptions, long lead times, and high total cost of ownership. Additive Manufacturing (AM) offers a compelling alternative: enabling on-demand, localized production of parts with improved agility, reduced carbon footprint, and enhanced supply chain resilience. The document focuses on the purchasing, qualification, and documentation of AM parts, addressing areas where existing standards require purchaser input and interpretation. The principles and guidance presented in this document are intended to support consistency and Quality Assurance (QA) across the procurement process. However, they are not meant to restrict innovation or flexibility. Manufacturers may propose, and purchasers may accept, alternative solutions or approaches—provided that any deviations are supported by mutually agreed requirements and evaluated on a case-by-case basis.
