ABS and Akselos partner to reshape FPSO Digital Twins Offshore Operations
The offshore oil and gas industry, a cornerstone of global energy production, faces relentless pressure to balance safety, efficiency, and cost in some of the planet’s harshest environments. Floating Production Storage and Offloading (FPSO) units, the workhorses of deepwater oil extraction, are among the most complex and capital-intensive assets in operation, often pushed to perform decades beyond their original design life. A groundbreaking collaboration between the American Bureau of Shipping (ABS) and Swiss software firm Akselos is redefining how these critical assets are managed, leveraging structural digital twin technology to enhance safety, reduce costs, and extend operational lifespans. This development, rooted in a recently completed technical assessment, signals a transformative shift in offshore structural integrity management.
A New Era of Asset Management
FPSOs operate in punishing conditions, battered by waves, wind, and corrosive saltwater while handling volatile hydrocarbons. Their structural integrity is paramount—not just for safety but for maximizing return on investment. Traditionally, operators have relied on periodic inspections and reactive maintenance, a costly and labor-intensive approach that often leads to unplanned downtime. Akselos’ Structural Performance Management (SPM) software, paired with ABS’s condition management tools, introduces a data-driven alternative: a high-fidelity digital twin that provides a near-real-time view of an FPSO’s structural health.
This digital twin integrates inspection records, metocean conditions (such as wave and wind data), and cargo operations into a dynamic model. The result is a continuous, live simulation of the FPSO’s structural performance, enabling operators to monitor stress concentrations, conduct on-demand fatigue analysis, and implement risk-based inspections. According to Akselos, this approach can reduce inspection and maintenance costs by up to 33%, as noted by Akselos. While exact savings vary, the reduction is considered significant across long-term 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, in a statement to Offshore Energy on May 7, 2025.
The collaboration builds on years of joint efforts, including deployments in Brazil’s Cessão Onerosa oil field, where digital twins have already demonstrated their value. By combining Akselos’ simulation technology with ABS’s Eagle Unified suite, the partnership offers operators a unified platform for asset performance management and regulatory compliance, streamlining operations across the asset lifecycle.
What is FPSO?
A Floating Production Storage and Offloading (FPSO) unit is a specialized vessel used in the offshore oil and gas industry to extract, process, and store hydrocarbons from deepwater fields. Anchored in remote ocean locations, FPSOs receive crude oil and gas from subsea wells, process them onboard, and store the output in large tanks until it can be offloaded onto tankers for transport. These complex, capital-intensive assets are critical for operating in harsh marine environments, often designed to withstand extreme conditions while ensuring safety and efficiency over decades of operation.
Safety and Efficiency in Focus
The stakes for FPSO operations are extraordinarily high. A structural failure can pose serious environmental and safety risks, along with high financial consequences for operators. Yet, the industry’s push for efficiency often clashes with the need for rigorous safety protocols. Digital twins address this tension by enabling predictive maintenance, which anticipates stress and fatigue before failures occur. This proactive approach not only enhances safety but also minimizes human exposure to hazardous environments, a critical consideration as the industry grapples with workforce safety standards.
Matt Tremblay, Senior Vice President of Global Offshore at ABS, emphasized the broader implications: “This collaboration reinforces the role of high-fidelity digital twin technology in the future of offshore structural integrity management. 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,” he told Riviera Maritime Media on May 8, 2025. ABS’s Condition Manager and Eagle Twin tools further enhance this capability, providing real-time load and condition monitoring within a digital twin framework that supports an FPSO from commissioning to decommissioning.
The financial upside is equally compelling. FPSOs are often deployed in remote fields where downtime—planned or unplanned—can cost millions per day. By reducing maintenance intervals and optimizing inspection schedules, digital twins improve operational cash flow while extending asset life. Offshore Engineer Magazine reported on May 6, 2025, that this data-driven approach “unlocks hundreds of millions of dollars in value through extended FPSO life and avoided production losses.” For operators, this means not just cost savings but the ability to extract more value from existing assets in an era of volatile oil prices and tightening environmental regulations.
A Proven Partnership
The ABS-Akselos collaboration is not a new venture but a deepening of a long-standing partnership. Their work in Brazil’s Santos Basin, particularly in the Cessão Onerosa field, has served as a testing ground for digital twin technology. There, the integration of Akselos’ SPM software with ABS’s condition management tools has enabled operators to simulate the structural integrity of entire FPSOs in real time, supporting data-driven decisions that enhance safety and efficiency. This success has paved the way for broader adoption, with Akselos signing a strategic enterprise agreement with Shell to further their collaboration on digital twin applications, as noted in Offshore Energy on May 7, 2025.
ABS, meanwhile, has been a pioneer in advancing digital technologies for offshore assets. Its work with BP on a floating production unit in the U.S. Gulf of Mexico and its approval of SBM Offshore’s NearZero FPSO design underscore its commitment to innovation. MarineLog reported on May 12, 2025, that this technical assessment builds on the long-standing collaboration between Akselos and ABS, highlighting the integration of Akselos’ software with ABS’s Eagle Unified suite for seamless asset management.
Industry-Wide Implications
The implications of this technology extend far beyond individual FPSOs. As the offshore industry faces increasing scrutiny over environmental impact and operational efficiency, digital twins offer a path to align with global sustainability goals. By reducing maintenance-related downtime and optimizing resource use, operators can lower their carbon footprint while maintaining production levels. This is particularly relevant for aging FPSO fleets, many of which operate in regions with stringent regulatory frameworks.
Moreover, the technology has potential applications in other high-stakes industries, such as offshore wind and maritime shipping, where structural integrity and real-time monitoring are equally critical. The ABS-Akselos model could serve as a blueprint for digital transformation across these sectors, driving innovation in manufacturing, logistics, and smart infrastructure. For enterprises managing complex assets, the ability to predict and prevent failures in real time represents a competitive edge in an increasingly data-driven world.
Challenges and Opportunities Ahead
While the promise of digital twins is undeniable, challenges remain. Implementing high-fidelity digital twins requires significant upfront investment in sensors, data infrastructure, and software integration. Operators must also navigate the complexities of regulatory compliance, particularly in regions with varying standards for digital asset management. Yet, the long-term benefits—cost savings, extended asset life, and enhanced safety—make a compelling case for adoption.
The ABS-Akselos collaboration is a testament to the power of partnership in overcoming these hurdles. By combining ABS’s expertise in classification and condition monitoring with Akselos’ cutting-edge simulation technology, the two organizations are setting a new standard for offshore asset management. As Offshore Energy noted on May 7, 2025, “This is expected to be accomplished by reducing inspection and maintenance costs, curbing planned and unplanned downtime, and enhancing safety by limiting human exposure in hazardous operational areas.”
