SPIE partners with SkyNRG on DSL-01 SAF plant in Delfzijl

Project and output

The DSL-01 plant at Delfzijl chemical park will produce 100,000 tons of sustainable aviation fuel per year and 35,000 tons of sustainable by-products (bio-sourced butane and naphtha). The sustainable kerosene is expected to enable CO₂ emissions reductions of up to 80% compared with fossil kerosene.

Design-to-operations maintenance role

SPIE has supported the project since its design phase for three years, focusing on ease of maintenance, safety and operational efficiency to prepare the upcoming maintenance phase. With financing secured and all permits granted, the project has entered construction and SPIE will translate design choices into a structured maintenance organisation.

Scope of services

SPIE will define maintenance processes, identify and manage risks, and set conditions for safe and efficient operation throughout the plant’s lifecycle. The company brings maintenance and asset management, breakdown services, project management, automation and control expertise to support the plant across activities and adapt to technological and energy developments.

Partnership and schedule

The plant represents SkyNRG’s move from fuel supplier to producer within a complex, evolving industrial environment where processes and organisations are still being established. Construction is underway and the facility is expected to be operational by mid-2028.
