How a European Nuclear Operator Connected 3,500+ Active Work Orders Across 1,400 P&IDs
Industry: Nuclear Energy
Region: Europe
Solution: Assai Viewport
Improving Maintenance Visibility in a Safety-Critical Nuclear Environment
At a European nuclear facility, operators needed real-time awareness of thousands of safety-critical work orders. Information was spread across SAP PM, AVEVA PI System and engineering drawings, making it difficult to detect work conflicts or understand their potential safety impact.
Assai Viewport brought maintenance, process and engineering information together in one governed environment, giving operators and engineers a clear view of ongoing work, affected systems and potential risks. The result was faster decision-making and safer maintenance planning.
The Challenge
Managing large volumes of maintenance activity in a nuclear facility created operational blind spots. Critical information was distributed across:
- SAP PM for maintenance work orders
- AVEVA PI System for real-time plant and process information
- Engineering drawings and P&IDs for engineering context
Operators had limited ability to identify simultaneous work that could create safety conflicts. Work orders and permits had to be manually correlated with affected equipment and systems, making it harder to maintain a complete operational picture.
The operator needed a single engineering information environment that could bring maintenance and plant information together to support safer, more informed operational decisions.
The Solution
Assai Viewport was implemented to provide a live operational view of maintenance activities. By connecting SAP PM, AVEVA PI System and engineering documentation, teams could see real-time plant status linked directly to P&IDs.
The platform enabled teams to:
- Visualise active maintenance work directly on P&IDs
- Connect real-time information from SAP PM and AVEVA PI System
- Recognise and connect tags and equipment items
- Access maintenance and engineering information across systems
- Identify simultaneous work and potential safety risks faster
Instead of manually checking information across separate systems, operators and engineers could see real-time plant status and maintenance activity in the context of the relevant engineering information.
Results
Assai Viewport created a governed operational view across maintenance and engineering information:
- 3,500+ active work orders visualised
- Over 1,400 linked P&IDs
- 300,000+ tagged items connected
- Improved insight and safety
Implementation enabled operators and engineers to identify work conflicts faster, improve coordination across maintenance activities and strengthen operational safety through real-time access to trusted engineering information.
Strategic Impact
By bringing maintenance, safety and engineering information together in one governed environment, the operator gained continuous situational awareness and reduced the risk of conflicting work.
The result is a scalable engineering information foundation supporting operational awareness, maintenance planning and continuous reliability improvement across its nuclear assets.
