TwinScie Project: Digital Twin for Oil Platforms

Project Overview

In collaboration with Petrobras and the University of São Paulo, I am contributing to the TwinScie project, which aims to develop an advanced digital twin ecosystem for oil platforms. This innovative project focuses on using artificial intelligence algorithms to detect mooring line breakages, a critical safety and operational concern in offshore oil extraction.

My Role and Contributions

As a research assistant specializing in concept drift detection and analysis, my primary responsibilities include:

1. Data Analysis and Pattern Recognition:

   • Analyze complex datasets comprising weather conditions, platform positioning, and mooring system status.
   • Identify patterns, trends, and seasonalities in the data using advanced statistical techniques and machine learning algorithms.

2. Visualization and Interpretation:

   • Create comprehensive graphical representations of the collected data.
   • Develop intuitive visualizations to effectively communicate trends and anomalies to both technical and non-technical stakeholders.

3. Statistical Analysis for Concept Drift Detection:

   • Conduct in-depth statistical analyses to detect potential concept drifts in the data.
   • Implement and refine algorithms capable of identifying subtle changes in data distributions over time.

4. Model Monitoring and Improvement:

   • Contribute to the continuous monitoring of AI models used in the mooring line breakage detection system.
   • Propose and implement improvements to enhance model accuracy and reliability based on concept drift findings.

5. Integration with Digital Twin Ecosystem:

   • Work closely with the team to integrate concept drift detection mechanisms into the broader TwinScie ecosystem.
   • Ensure seamless data flow and real-time analysis capabilities within the digital twin framework.

Key Project Objectives

• Enhance the accuracy and reliability of mooring line breakage detection using a combination of real and simulated data.
• Develop robust AI algorithms capable of functioning effectively across various platform types and environmental conditions.
• Implement a comprehensive data quality validation system to ensure the integrity of AI algorithm training.
• Create an adaptive system capable of identifying and responding to concept drifts in real-time.
• Establish a scalable solution that can be deployed across multiple platforms in Petrobras’ fleet.

Technical Challenges and Innovations

1. Data Scarcity: Addressing the limitation of real failure event data through advanced simulation techniques and transfer learning approaches.

2. Algorithm Ensemble: Combining multiple AI approaches to improve overall fault detection accuracy and robustness.

3. Automated Lifecycle Management: Developing systems for automated training, deployment, and monitoring of AI models within the digital twin ecosystem.

4. Real-time Processing: Implementing efficient data processing pipelines capable of handling high-volume, high-velocity data streams from multiple sensors.

5. Concept Drift Adaptation: Creating adaptive learning mechanisms that can automatically retrain models in response to detected concept drifts.

Impact and Future Directions
