4Subsea has been awarded a three-year service agreement with Vår Energi to monitor and analyse wellhead integrity to ensure safe operations for the Balder Future drilling and completion operations.  The SWIM™ service employs retrofittable subsea sensors to measure movement and strain on the wellhead. It applies advanced algorithms and machine learning combined with deep domain expertise to monitor fatigue damage accumulation, well support and structural integrity.  

The service creates a digital twin of the well and riser systems combined with boundary conditions and updated with sensor data. Sensor data is collected using remotely operated underwater vehicles and uploaded to 4Subsea’s digital service 4insight^®, which performs advanced analysis on the data. The results are presented as easy-to-interpret insights and dashboards, simplifying the complex analysis and effectively support critical decisions. No extra personnel are required and supported by advanced algorithms and machine learning. In addition, 4Subsea’s domain experts provide a digital service for improved decision support to Vår Energi’s engineering team to ensure safe operations.

The same sensors, technology, and algorithms have been adapted to monitor fatigue and integrity on offshore wind installations, demonstrating the versatility and robustness of 4Subsea’s sensor technology and digital services.

“We are pleased that Vår Energi has chosen SWIM™ and 4insight^® for their drilling and completion operations on Balder Future operations. These services have proven to reduce operational risk and costs during complex operations and are great demonstrations of the digital transformation of offshore operations to increase safety”. CEO of 4Subsea, Peter Jenkins.
