Digital Twin Rollout Across North Sea Platforms Delivers 7% Production Uplift

The North Sea portfolio comprises several mature platforms, each with unique process configurations and aging infrastructure. Historically, production optimization relied on a mix of legacy control systems, offline models, and expert judgment.
While these assets remained technically sound, their operational visibility was fragmented — engineers worked with data scattered across PI historians, maintenance systems, and spreadsheets. Key challenges included:

• Limited insight into real-time flow assurance and equipment performance.
• Reactive rather than predictive maintenance planning.
• Manual coordination between offshore operators and onshore engineers.

In 2021, client’s leadership team defined a strategic target: build an integrated digital twin ecosystem to improve production reliability, reduce downtime, and provide data-driven decision support across all North Sea assets.

The initiative aimed to:

1. Integrate operations data (process, maintenance, and simulation) into a unified digital twin.
2. Enhance production optimization by enabling real-time monitoring of wells, compressors, and flow networks.
3. Enable predictive maintenance and proactive troubleshooting through AI-based anomaly detection.
4. Establish a replicable digital twin architecture for deployment across client’s global upstream portfolio.

Architecture and Integration
The project utilized a hybrid cloud-edge architecture, combining on-platform data acquisition with cloud-based analytics. Each platform’s control system streamed telemetry to a data lake, feeding both a high-fidelity physics-based simulator and a machine-learning layer trained on historical operations.

Digital Twin Core Components:

• Process Model: Steady-state and transient simulations calibrated against 3 years of operating data.
• AI Analytics Layer: ML algorithms for anomaly detection, flow-rate optimization, and energy efficiency.
• 3D Visualization Interface: A fully navigable virtual model of each platform, synchronized with live process data.
• Integration Backbone: APIs linking the twin with PI System, SAP PM, and maintenance dashboards.

Deployment Process
The rollout followed a structured four-phase approach:

1. Pilot Phase (Q1–Q2 2022): A limited deployment to validate data flows and model calibration. The pilot identified early optimization opportunities worth 2% production gain.
2. Scale-Up (Q3–Q4 2022): Integration extended to four additional platforms. Edge gateways standardized data formats across heterogeneous control systems (ABB, Honeywell, Yokogawa).
3. Operations Adoption (Q1 2023): Cross-disciplinary training delivered to 120 engineers and offshore supervisors.
4. Full Rollout (Q2 2023): System replicated across the entire North Sea portfolio, enabling real-time benchmarking of production KPIs between assets.

After six months of steady-state operation, measurable results included:

• 7% uplift in overall production efficiency, attributed to optimized choke settings, compressor sequencing, and flow assurance adjustments.
• 18% reduction in unplanned deferments, driven by early detection of hydrate formation and pressure anomalies.
• 30% faster troubleshooting, as engineers could simulate and validate interventions virtually before field execution.
• 10% energy efficiency gain, thanks to improved compressor load management and reduced flaring events.

Moreover, the digital twin allowed client’s central operations center to run “what-if” scenarios in real time, improving coordination between offshore and onshore teams.
