Resumo:The Offshore Oil & Gas industry faces pressure to minimize downtime, improve supply chain responsiveness, and align with sustainability objectives. Traditional manufacturing methods struggle to provide necessary agility in remote offshore settings. This dissertation explores Additive Manufacturing’s role, specifically Selective Laser Melting, through Techno-Economic Analysis, manufacturing, and Life Cycle Analysis. Investment Casting was chosen as the reference method, as both processes can produce high-complexity metal components. The TechnoEconomic Analysis was developed for Additive Manufacturing and benchmarked against a pump impeller for Investment Casting. Per-part costs and lead times were calculated, and the Selective Laser Melting process was chosen for manufacturing using an SLM 280HL machine to produce a functional pump impeller. The data informed the Lifecycle Analysis, structured around the EF3.0 methodology. Results show Selective Laser Melting has higher per-part cost (9 698.93 NOK) versus Investment Casting (6 428.47 NOK), but offers significant lead time advantages. The Additive Manufacturing supply chain reduced lead time from 12 weeks to 3.2 days . With offshore downtime costing operators up to millions of NOK daily, preventing one week’s delay through Additive Manufacturing can avoid substancial economic loss, outweighing the cost premium. The successful impeller production validated Selective Laser Melting’s capability for toolless manufacturing of complex components. The Life Cycle Analysis showed that despite higher fabrication energy, holisticly, Selective Laser Melting provides environmental benefits through reduced transport, warehousing, and increased circularity. The digital nature of Additive Manufacturing enables distributed production, creating opportunities for localized spare parts systems in offshore operations. This research positions Additive Manufacturing as a catalyst for reinventing offshore operations, transforming downtime into uptime and environmental risk into sustainable opportunity. In this pressured sector, Additive Manufacturing emerges as mission-critical.
