Sustainable Framework to Reuse and Recycling Subsea Flexible Pipes for Industrial Plants Facilities

# metadata.dc.description.abstract[].value
The decommissioning of flexible pipelines in the offshore oil and gas industry presents both environmental challenges and opportunities for resource recovery. This study proposes a Sustainable Pipeline Upcycling Framework that integrates circular economy (CE) principles and additive manufacturing (AM) techniques to transform decommissioned flexible pipes into valuable industrial components. The research follows a multi-phase methodological approach, including Focus Group Interviews, Fuzzy Delphi, and Fuzzy DEMATEL, to systematically identify, prioritize, and map causal relationships among barriers and drivers influencing framework adoption. Key barriers identified include limitations in AM scalability, challenges in material qualification, and high initial investment requirements. On the other hand, enabling drivers such as advancements in 3D printing, sustainability policies, and cost reductions through on-demand production were found to exert strong causal influence over these barriers. The findings offer strategic insights for managers and policymakers seeking to implement sustainable decommissioning practices while enhancing operational efficiency and environmental performance in both emerging and developed economies.
