Structural analysis and life extension of fixed offshore assets

Oil and gas platforms operate in demanding conditions that require a real time assessment of risk and cost to operate efficiently. Traditional approaches to structural analysis don’t support global system models at a level that accurately reflects physical models, and can’t accurately capture cumulative effects in the global structural model. Akselos offers a full-cycle approach with a predictive Digital Guardian that offers a step change in Asset Management.

Structural analysis and life extension for offshore floating structures

Offshore floating structures used within the oil and gas industry must withstand extreme environmental loads, and are consequently designed not only for safety, but also for long-term performance and reliability. Akselos is the only near real-time structural integrity tool providing holistic, detailed models that help you enhance durability of offshore installations with greater upfront confidence in designs and life extension decisions.

RB-FEA based Digital Twin for structural integrity assessment of offshore structures

The speedup and level of detail achieved through the reduced basis finite element analysis (RB-FEA) technology is a key enabler for the Akselos’ digital twins. Thanks to sensor data integration it enables true condition-based modeling of large and critical assets, allowing all relevant structural details to be included in the model. The result is the ability to operate critical assets beyond their design life.

Accurate fatigue failure analysis with Akselos Decision Support System

The Decision Support System is a powerful tool within the Akselos Integra platform that provides engineers with a holistic view of the model’s strength and stability, at the same time, for different loading conditions. It can be used to automate standards-based analyses by post-processing load case results using codes from class societies (e.g. Lloyd’s Register, DNV-GL, ABS, etc.). The tool then generates reports that summarize critical issues. Results are displayed on the model so users can see which specific components are over-strength or under-strength based on predefined tolerances. This is an immense timesaving tool that aids engineers in assessing the reliability of their designs and assets quickly and efficiently.

Akselos seamless workflow for 3D joints

Move from beams to a fully-meshed 3D joints model - according to DNVGL-RP-C203. Akselos RB-FEA technology allows for more accurate hotspot stresses, less conservative fatigue results to support decisions regarding life extension.

Akselos’ Optimal Workflow for Structural Assessment

Floating structures, such as FPSOs, tankers, and semisubmersibles, are very large and complex assets that greatly benefit from the fast, holistic, and detailed modeling provided by Akselos’s RB-FEA technology. In this report we provide documentation of the accuracy and reliability of Akselos’s solvers for floating assets.

Akselos SIMLAB series #1: Continual Remote Monitoring of Large Assets with Simulation

Akselos is a new simulation technology that can evaluate structural behaviour 1000x faster than traditional techniques. Akselos is capable of producing high-fidelity, physics-based models of large complex assets which may be connected to sensor data to regularly update the simulation model and provide the required assessments in a timely manner. Such simulation models are termed Structural Digital Twins and provide a continual picture of structural integrity that can be used to optimise operations and maximise life.

Offshore Wind: Smart Design and Fabrication with Digital Twins co-hosted with Lamprell

In this webinar, you’ll hear about the collaboration between Lamprell and Akselos to fully optimize the end to end design process of each of the components in a wind turbine through constructible designs and structural digital twins. The partners aim to achieve a reduction in CAPEX, improved future design and optimized operations through Risk Based Inspection when the turbines / foundations are operational.

Digital twins for high performance wind system engineering and exascale deployment

Akselos Physic-Based Predictive Digital Twin, a mechanical simulation of the wind turbine that can be continually analysed, and re-analysed, throughout the life of the asset. Combined with sensor data from real turbine, the Digital Twin provides Top Predictive Power.

Akselos SIMLAB series #3: Advanced Contact and Plasticity Analysis for Large Problems

Large, three dimensional contact problems are among the most challenging problems for structural simulation systems. Converged solutions are often difficult to obtain, especially when the additional effects of friction and material plasticity are significant. Akselos Reduced Basis Finite Element Analysis (RB-FEA) is a new approach to structural simulation which is 1000x faster than conventional techniques. Akselos contains a hybrid solution capability that may be used to greatly increase the speed and stability of contact models. These computational benefits allow contact effects to be included within models of in-service scenarios resulting in enhanced predictive capabilities. This webinar will provide an overview of these capabilities and how they may be applied to both design and in-service applications.

World’s Largest Digital Twin: Akselos’ successful deployment for Shell’s Bonga Main FPSO

Our structural Digital Twin technology was applied to the Shell Bonga FPSO, becoming the largest asset in the world to be protected by a structural Digital Twin. With near real-time analysis, the physics-based model of the asset allows Shell and Akselos to monitor the overall health of the asset, reduce down time and boost efficiencies, all while enabling safe asset life extension. Watch our latest video to find out how Akselos’ RB-FEA technology is helping transform the future of the FPSO industry.
