Upcycling of Subsea Flexible Flowlines into Value-Added Materials
The project aims to develop innovative upcycling solutions for decommissioned subsea flowlines, processing them into viable construction materials. These solutions will address a materials gap in the industry, with the retrieved materials intended for use in renewable energy and Defense installations. The project encompasses various scopes aimed at developing innovative upcycling solutions for decommissioned subsea flowlines. Initially, the focus lies on characterizing these flowlines, which are composed of layers of polymer and stainless steel, addressing challenges posed by chemical degradation, corrosion, and naturally occurring radioactive material contamination. Subsequent efforts involve the development of a cost-effective separation process for the flowlines, optimizing products to meet end-user requirements in construction and other sectors, and establishing a pilot recycling facility. Additionally, compliance, education, and training aspects are integral, including disseminating knowledge, creating compliance reports, and developing national training programs to engage potential end-users and integrate educational initiatives. The project aims to create high-value upcycled products for infrastructure applications, collaborating closely with relevant industries to ensure feasibility and applicability at an industrial scale.
