ABS and Akselos advance digital twin technology for FPSOs

The American Bureau of Shipping and Akselos S.A., provider of structural performance management software have completed a joint technical assessment for structural digital twin technology, enabling more accurate and reliable assessments of structural integrity for FPSOs

The digital twin solution can reduce inspection and maintenance costs by up to 33%, minimising both planned and unplanned downtime by predicting stress and fatigue before failures occur, and enhancing safety by limiting human exposure in hazardous operational areas. This ultimately saves millions of dollars by extending FPSO life and minimising production losses.

Akselos’ SPM software provides a high-fidelity, near real-time digital twin of the entire FPSO. By combining inspection records, metocean conditions, and cargo operations into one dynamic model, operators have access to a live, continuous view of structural performance. This facilitates real-time monitoring, identification of stress concentrations, and on-demand fatigue analysis to support data-driven maintenance and risk-based inspections.

When combined with ABS’ Condition Manager and Eagle Twin inspection data management and condition tracking software tools, the Akselos software is capable of monitoring real time load and condition information within a digital twin framework that enables full life cycle support of an offshore asset. Akselos’ SPM software also integrates with ABS’s Eagle Unified suite, providing operators with a unified platform for asset performance management and class compliance.

“This collaboration reinforces the role of high-fidelity digital twin technology in the future of offshore structural integrity management,” said Matt Tremblay, senior vice president, Global Offshore at ABS. “By combining real-time operational data with advanced simulation, Akselos is enabling a more predictive and performance-based approach to asset management—fully aligned with the industry’s drive toward safer, more efficient operations.”

“This joint work confirms the robustness of our software and reinforces the growing momentum for digital transformation in offshore oil and gas,” said Claus Reimers, chief product and technology officer at Akselos. “We enable operators to simulate the structural integrity of the entire FPSO in real time and at full fidelity—supporting smarter, safer decisions across the asset lifecycle.”
