Bilfinger and Schneider Electric have successfully completed a major offshore automation milestone with the deployment of an autonomous Normally Unmanned Installation (NUI) buoy in the North Sea. The pilot demonstrated how renewable-powered infrastructure and advanced automation systems can support remote offshore operations without permanent offshore personnel or traditional power and control umbilical connections.

Developed for Buoyant Production Technologies (BPT), a subsidiary of Crondall Energy, the autonomous offshore buoy completed 1,000 hours of operation following deployment in late 2025. The project was designed to evaluate a new approach for supporting remote and marginal offshore developments through compact, self-powered infrastructure.

Bilfinger was responsible for designing and delivering the control system, using Schneider Electric’s EcoStruxure Automation Expert platform. The software-defined automation architecture provides a flexible foundation for autonomous offshore operations by separating automation applications from traditional hardware limitations.

The pilot represents a shift in how offshore assets can be designed and operated. Conventional offshore developments often depend on large fixed platforms, extensive subsea connections, and complex infrastructure networks. The autonomous buoy model introduces an alternative approach by combining renewable energy generation, remote communication, and intelligent control systems into a smaller and more adaptable installation.

The floating NUI buoy generates its own power through an integrated renewable energy microgrid that combines wind generation, solar power, battery storage, and backup diesel generation. This hybrid energy system allows the platform to operate independently while supporting local subsea controls and monitoring functions.

By eliminating the requirement for conventional power and control umbilicals connected to host platforms, the technology could significantly simplify offshore development strategies. According to the companies involved, the approach has the potential to reduce development costs for remote offshore assets by up to 50% while lowering emissions and improving infrastructure flexibility.

“This approach simplified integration between renewable power generation, remote operation, and autonomous control, while overcoming the long lead times, high capital costs, and limited flexibility associated with traditional infrastructure,” said Steven Parkinson, automation, production and service director at Bilfinger UK.

The project highlights the growing importance of autonomous offshore automation systems as energy companies seek more economical solutions for smaller fields and challenging offshore environments. Instead of relying exclusively on large-scale offshore platforms, operators are increasingly exploring modular and digitally connected assets that can be deployed faster and managed remotely.

Schneider Electric’s software-driven automation approach enables operators to integrate control, monitoring, and operational intelligence into a unified environment. Technologies such as Schneider Electric Triconex safety systems are widely used in critical industrial environments where reliability, safety, and continuous operation are essential.

The autonomous buoy uses remote communication technologies, including 5G and Starlink connectivity, to maintain communication between offshore equipment and onshore operators. Onboard systems provide process control, safety monitoring, and cybersecurity protection, allowing teams to supervise operations without requiring regular offshore intervention.

The successful pilot demonstrates how digital technologies are reshaping offshore production models. By combining renewable energy systems, remote asset management, and intelligent automation platforms, operators can create more efficient infrastructure while reducing exposure to harsh offshore environments.

“This project proves a new operating model for offshore assets and supports our mission to decarbonize hard-to-abate industries,” said Devan Pillay, president of Heavy Industries at Schneider Electric. The company added that the next opportunity lies in scaling the concept across future offshore developments.

The project was completed from contract award to technology qualification in approximately 10 months, showing the potential for faster innovation cycles in offshore engineering. The successful demonstration provides a reference point for future subsea tieback projects where operators are looking to reduce capital intensity and improve operational sustainability.

As offshore developments move toward greater digitalization, autonomous installations are expected to become an increasingly important part of the energy industry’s future. Smaller, smarter, and remotely operated assets may provide operators with new options for developing previously uneconomical fields while supporting emissions reduction goals.

The Bilfinger and Schneider Electric collaboration demonstrates how automation architecture, renewable power integration, and advanced communication technologies are converging to create the next generation of offshore operations.
