How do you plan and execute subsea wellhead maintenance and intervention?

For assessing the will condition, data is key. Utilising advanced inspection technologies and methodologies and collecting refined data to be able to analyse and create an execution plan. NDT methods coupled with digital twins are effect in planning the scope so a visual aid is available. Incorporating environmental and geological assessments for the immediate surroundings help us with evaluating external factors. The key is predictive maintenance and being proactive. I prefer a life-cycle management approach to understand the history of the wellhead and not just the immediate maintenance requirements, the goal is long term performance and factoring life of the assets including decommissioning strategies.

The latest techniques for subsea wellhead assessment include failure prediction methods for risk identification, a Subsea Wellhead Retrieval Tool for one-step cutting and recovery, diagnostic methods for high-voltage components, and finite element analysis for structural assessment. These approaches enhance the understanding of potential failures, retrieval processes, insulation conditions, and structural behavior, contributing to improved subsea wellhead management.

Utilize ferramentas de monitoramento remoto e inspe??o, como sensores submarinos e ROVs para coletar dados precisos sobre a condi??o do po?o. Uma inspe??o visual e a análise de dados históricos ajudam a determinar o escopo exato da interven??o necessária.

Equinor utilizes Remote Operated Vehicles (ROVs) and Unmanned Underwater Autonomous Vehicles (UAVs) for efficient subsea operations. ROVs, operated remotely from the surface, perform tasks such as inspections and repairs. UAVs, autonomous underwater vehicles, contribute to data collection and surveillance. Equinor's deployment of these technologies enhances safety and precision in their subsea activities, allowing for effective monitoring, maintenance, and exploration beneath the ocean's surface.

Resource review is important, once personnel and equipment are selected, compatibility checks are needed for technology integrations. Operational excellence comes from having the right gear such as remote option abilities like ROV technologies which reduce high-risk human exposure. It's crucial to implement robust contingency planning and prepare for failures, changes and challenges.

A pragmatic approach using stages or steps within the project to get it right the first time. Ensuring remote operations and in some cases with AI-assisted decision making capabilities with management oversight. Communication is key, the interface between surface operations and subsea equipment on high speed communication links. Use integrated controls to your advantage from various system sources like cameras, sensors and instruments. Precision is key so high resolution imagery and new technology is paramount for testing and verification. In trouble shooting a systematic approach is best, going back to basics and back to the book.

Well intervention, essential for oil and gas wells, involves maintaining, repairing, or enhancing their performance. It extends well life, boosts productivity, and prevents environmental issues. Recent IT technologies in this field include Digital Twins—virtual models optimizing well performance, reducing costs, and enhancing safety. Artificial Intelligence (AI) analyzes complex data, offering insights and predictions for improved interventions. Robotics, focusing on robot design and operation, aids in hazardous or challenging tasks like inspection and repair, contributing to safer and more efficient well interventions.
