The new compressor range combines reliable, high-pressure air supply for offshore well testing, drilling, production, and maintenance operations with significantly lower emissions than conventional diesel-powered alternatives, supporting more sustainable offshore energy production.
James Fisher’s team in Norway is leading the development of scalable, lower-carbon solutions for offshore energy production. The 25-strong fleet is being manufactured in Stavanger, turning pioneering innovation into real-world impact across the offshore energy sector.
These include the ST25EL, a high-output air electric compressor, and the ST10EL, an ultra-compact variant designed for small back deck environments.
The technology has already delivered measurable environmental and commercial benefits offshore. During a recent drilling project, five ST25EL electric compressors reduced CO2 emissions by 160 tonnes compared with conventional, diesel-powered alternatives.
In a separate well drilling campaign, two ST25EL units enabled remote operations, cutting emissions by a further 70 tonnes while delivering cost savings of approximately $62,000 through lower fuel consumption and averted carbon tax costs.
These results are backed by an independent lifecycle assessment using an ISO 14040-aligned methodology, which found the ST25EL can reduce lifecycle greenhouse gas emissions by up to 94% when powered by the Norwegian energy grid, and by 23–25% even when powered by a diesel generator.
Neil Sims, Head of Energy at James Fisher, said: “Offshore operators are under increasing pressure to maintain reliable production while reducing emissions and operating costs. Our new electric compressor fleet has been developed to help customers achieve all three without compromising performance. By combining significantly longer operating runtimes with lower emissions and reduced maintenance requirements, we’re providing a practical solution that supports today’s operational demands while helping customers prepare for the future.”
Andreas Fliss, Country Manager (Norway) for James Fisher, added: “Through our market research and customer feedback on the need for lightweight, powerful, and carbon tax-aligned solutions, James Fisher has drawn upon its in-house engineering and R&D experience to bring the electrified compressor range to market through its own supply chain. Both the ST25EL and ST10EL enable safe, reliable well operations while directly addressing both security of supply and decarbonization goals. These practical, scalable solutions demonstrate our commitment to technological innovation in supporting the needs of our customer base internationally.”
James Fisher and Sons plc will be exhibiting at ONS Norway in Stavanger, August 24–27, 2026, and will present on the real-world impact of electric compressors during the ‘Powering Net Zero’ technical session on Thursday, August 27.
