4Subsea Secures Supply Agreement to Monitor Steel Catenary Risers Offshore Brazil

4Subsea has been awarded a supply agreement to monitor steel catenary risers on the Floating Production Storage and Offloading’s (FPSO) on the Bacalhau field in Brazil.

The service is delivered using 4insight® Subsea Asset Integrity which combines advanced strain and motion sensors to measure vessel motions and riser load with algorithms to calculate riser pressure and hoop stress to monitor the integrity and risks to steel catenary risers on the FPSO. The digital service is delivered as monitoring dashboards and data fed into Equinor’s data platform for further analysis.

The riser monitoring service provided at Bacalhau is an application of 4insight® Subsea Asset Integrity, a digital service that continuously monitors the physical integrity of different subsea and offshore infrastructures using retrofittable autonomous sensors and algorithms and machine learning methods optimised for different assets and measurements. The results are presented as easy-to-interpret insights and dashboards, simplifying the complex analysis and effectively support critical decisions. The data is also available through open APIs, which the Operator’s own data platforms can access for further analysis.

Peter Jenkins, CEO of 4Subsea, said: “We are pleased to be chosen to monitor the integrity of the risers at Bacalhau. 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.”

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