Title:

Model-based approach for re-evaluating the multi-discipline performance of a Check Valve for Hydrogen processing

Abstract:

Renewed interest in a low-carbon economy by governments and companies across the world to achieve a net-zero vision have reinvigorated efforts to re-qualify or re-engineer industrial facilities that can make this vision a reality. In particular, interest in a Hydrogen-supported economy, where Hydrogen is first used for long-term energy storage and eventually used as fuel, has meant that facilities initially certified for other applications (like natural gas storage), need to be re-evaluated to satisfy new demands on their equipment.  In this presentation, we focus our efforts on the multi-physics virtual validation of a check valve operating in one such facility assuming an increased demand on its operating pressure conditions and a requirement to sustain a wider temperature range.

By using Dassault Systèmes 3DEXPERIENCE platform, we demonstrate how the engineering work required for validating the performance of a check valve can be carried out in a model-based collaborative engineering environment.  The multi-physics validation encompasses the use of both, fluid and structural mechanics disciplines that operate in synchrony to provide a complete assessment of the flow characteristics and structural integrity of the valve. The model-based approach has been proven to reduce cycle time in assessing the multi-discipline evaluation of this piece of engineering equipment, while maintaining full traceability of the overall process.

Title:

Fully coupled multi-physics modeling of hydraulic fracturing using Abaqus

Abstract:

In this presentation, we will provide an overview of fully coupled multi-physics simulation capabilities for modeling of fluid-driven (hydraulic) fractures. These models are based on a fully-implicit non-linear FE solver, and comprise two widely established fracture modeling methods: Cohesive Zone Method or CZM (mesh conforms to a pre-defined fracture path) and eXtended Finite Element Method or XFEM (fracture geometry evolves independently of the finite element mesh). Through a series of illustrative examples, we will also demonstrate the applicability of these fracture modeling capabilities in capturing the influence of various geomechanical and operational parameters on hydraulic fractures, such as in-situ stress, fracturing fluid viscosity, formation permeability, presence of other fractures in near vicinity and effect of depletion.

Title:

Design Verification of Downhole Completion Tools Using Abaqus

Abstract:

Completion tools are installed for oil/gas production after drilling operation. The main completion tools include flow control, safety valve, liner hanger, packer, etc. Design verification is a rigorous analysis process to ensure that the designed tool has enough margin or protection against failure for the anticipated downhole operating conditions. A completion tool is usually designed and test validated along a performance envelope. In the performance plot, one axis is the axial load, the other axis is the (differential) pressure. The performance envelope illustrates the combined effects of (differential) pressure and axial loads at the rated temperature and defines the maximum safe operational limit of the tool. The performance envelope is usually derived from a customer’s Statement of Requirement (SOR), and the customer’s well operating conditions are on/within the rated performance envelope. In this presentation the latest design verification requirements for safety valve (API 14A), packer (API 11D1), and liner hanger (API 19LH) are compared, the safety margin/load factor and failure mode analysis for the performance envelope of a liner hanger using Abaqus are demonstrated. As geometry imperfections (such as ovality, eccentricity and non-uniform thickness) from manufacturing have great effects on the collapse pressure rating, the effect of ovality on the performance rating is also investigated.

Title:

Welding Simulation with Abaqus & QustomWeld

Abstract:

Welding simulation has long been performed using Abaqus, but Abaqus lacked the specific capabilities required to perform welding simulations efficiently. That changed in 2018 when Dassault Systems released it first capabilities for simulating the additive manufacturing processes. Although the tools were developed for the additive manufacturing process, the on-the-fly element activation, moving heat fluxes, phase transformation and other capabilities lend themselves well to simulating the welding process. QustomWeld is the first commercial tool to take advantage of the capabilities and make them easy to use within a fully integrated interface inside of Abaqus/CAE. This discussion will cover the capabilities of QustomWeld including deposition welding, beam welding, phase transformations, robot controls, and more.

Title:

Integrating Laser Scan Data into FEA Model to Perform Level 3 Fitness-for-Service Assessment of Critical Assets in Refinery & Process Industries

Abstract:

Fitness-for-service (FFS) assessment of safety critical equipment in process and petrochemical industries is an important engineering activity from the perspective of determining the structural integrity of assets. FFS enables an engineer to determine whether the equipment or facility needs a repair, or replacement, or whether it is good to continue for its remaining life or until a planned outage. One of the key aspects for an accurate FFS assessment is to include the current geometric configurations of the structure. With new inspection technologies such as laser scan it is common to gather very accurate information on the current deformed state of the structure. However, the challenge remains in how to utilize and integrate a large volume of data in subsequent high fidelity structural analysis. 

This work describes a methodology used to analyze a structure for Level 3 FFS, such as storage tank. Using field laser scan data, the surface points of the storage tank is imported to create geometrical surface in a CAD software (CATIA), and then importing that surface in an FEA model (Abaqus) for FFS assessment. The step of direct import of scan data 
into CAD software to generate the digital twin of the structure eliminates the ambiguity of assuming a surface by an engineer that may not be a realistic representation of the true damaged surface. This work shows the complete workflow of importing a laser scan data of a storage tank into CAD, creating a realistic surface from the scan data, and importing that realistic surface into FEA software to perform detailed Level 3 FFS of the tank using Abaqus.

Title:

Abaqus Plug-in Library and Hybrid Performance of Abaqus Standard

Abstract:

There is considerable interest in add-ons to Abaqus pre and post processing (plug-ins) and hybrid architecture performance of Abaqus solver on HPC systems. JBL Technologies presents a library of pre and post processing plug-ins to generate parametric models, create material properties using ASME codes, and post-process for data management. 

Further, with the acquisition of a local HPC of 128 cores, hybrid computing performance of Abaqus is studied. While scaling of the Abaqus explicit solver has been studied extensively, Abaqus standard scaling tests are rather limited. Such simulation cases can arise in many industries like the automotive industry where pre-loading of the cylinder head onto the engine block with plastic loading of the gasket can be studied. For the test case, an engine model with a large DOF (> 1e6 DOF) is studied.  It is demonstrated that a 10-15% performance improvement can be achieved when using a balanced hybrid computing mode and should be the preferred mode of solving such problems.

Endurica DT Co-simulation for Elastomer Material Property Evolution under HPHT Conditions

Abstract:

At elevated temperatures, elastomers undergo thermochemical changes that drive the evolution of elastic and strength/fatigue properties. Endurica DT’s incremental co-simulation workflow is applied to the analysis of a seal under dynamic HPHT conditions. The ageing effect is specified via the Arrhenius law (ie an activation energy), in combination with master curves detailing the evolution pathways for stiffness, tear strength and fatigue limit. Due to material property evolution, the stress-strain fields in the seal must be updated periodically by Abaqus through Endurica DT’s cosimulation interface. The combined effects of ageing and fatigue on material property evolution and crack growth through a specified thermomechanical operating history are thus tracked, enabling lower risk materials selection and design.

Title:

Mechanics and Simulation of Double-Shoulder Threads for Downhole Applications

Abstract:

Thread analysis is a critical structural analysis for downhole applications in the oil and gas industry, where strength and sealing performance of the thread connection is evaluated under the design load envelope. The first step of thread analysis is to model the pre-stressing effects caused by the initial make-up-torque. This modelling is typically done by applying an interference fit in 2D axisymmetric simulations using the well-known power-screw equation. However, interference calculations become challenging if the thread design and geometry are not conventional, such as double-shoulder threads, because the power-screw equation is no longer applicable. The goal of this paper is to establish a general method to numerically calculate the interference fit applicable to both single-shoulder and double-shoulder threads using 2D axisymmetric models. The torque mechanisms of single-shoulder and double-shoulder threads are first compared, and then a new equation is developed to extend the application of power-screw equation to double-shoulder threads. Full 3D simulations followed by 2D axisymmetric finite element analyses are conducted to better understand the mechanics of the problem and verify the proposed method. The analysis results confirm the substantial difference in mechanics of the single-shoulder and double-shoulder threads and the way torque-induced axial force is distributed. Finite element analyses reveal the high fidelity of the proposed methodology, where the results of 3D and 2D simulations as well as the predictions of the proposed equation come into good agreement. The results of this study can substantially improve the make-up torque simulation of threads using 2D axisymmetric models.

Engineering and design of shrouding for LNG pipes using Abaqus

Abstract:

In the United States, regulatory code 49 CFR Part 193, and standards such as NFPA 59A provide safety guidelines for Liquefied Natural Gas (LNG) facilities. These stringent structural design requirements are enforced to ensure no loss of structural and functional integrity. Conventionally inside LNG facilities pipe shrouding is installed as a protective structure surrounding the LNG pipelines. Therefore, the pipe shrouding must meet the design requirements under wind forces and various design spill scenarios.  In this study, Abaqus was used to perform the mechanical and thermal analysis of the pipe shrouding. In this case, nonlinear inelastic analysis was performed where both geometric and material nonlinearities were considered. Additionally, for the design checks under environmental loading elastic analysis was performed. In performing the analysis Abaqus’ in-built parallel processing was utilized. The strength and serviceability design checks were performed using the state variables - von Mises stress and displacement. Python scripts were employed to extract state variables and to plot the stress contour from the output files. Finally, the shroud geometry was exported from the model database files into files of ‘STP’ format to perform clash check with field cloud point data using the software Navisworks. The same ‘STP’ files were also applied to create models for the fabricator in the Tekla software.

Title:

Modelling Bow Spring Centralizers for Casing Stand-off Estimation

Abstract:

Optimal casing centralization is critical in achieving proper fluid displacement. In cementing applications, proper casing stand-off helps in the prevention of mud channeling and hence increases the likelihood of achieving zonal isolation objectives. In open-hole completion applications, it benefits fluid displacement when swapping drilling mud with completion fluids. The use of a stiff-string formulation in addition to the real bow centralizer behavior will provide the best possible solution for casing stand-off estimation in the industry. This study will demonstrate how to use tube-in-tube elements to mimic the non-linear force-displacement behavior of bow spring centralizers.

Fitness-for-service (FFS) assessment of safety critical equipment in process and petrochemical industries is an important engineering activity from perspective of determining the structural integrity of assets. FFS enables an engineer to determine whether the equipment or facility needs a repair, or replacement, or whether it is good to continue for its remaining life or until a planned outage. One of the key aspects for an accurate FFS assessment is to include the current geometric configurations of the structure. With new inspection technologies such as laser scan it is common to gather very accurate information on the current deformed state of the structure. However, the challenge remains in how to utilize and integrate a large volume of data in subsequent high fidelity structural analysis. 

This work describes a methodology used to analyze a structure for Level 3 FFS, such as storage tank. Using field laser scan data, the surface points of the storage tank is imported to create geometrical surface in a CAD software (CATIA), and then importing that surface in an FEA model (Abaqus) for FFS assessment. The step of direct import of scan data into CAD software to generate the digital twin of the structure eliminates the ambiguity of assuming a surface by an engineer that may not be a realistic representation of the true damaged surface. This work shows the complete workflow of importing a laser scan data of a storage tank into CAD, creating a realistic surface from the scan data, and importing that realistic surface into FEA software to perform detailed Level 3 FFS of the tank using Abaqus.

Optimization of Aerospace Structures via Abaqus and Tosca: A Survey of Senior Student Projects

Abstract:

With its wide range of analysis capabilities, ease of use, and powerful scripting capabilities, Abaqus has become the tool of choice for teaching the concepts of structural analysis and design to senior Aerospace Engineering students at Texas A&M University. Since 2013, students seeking to build standout capabilities in this area have taken one particular course that reviews FEA concepts and the use of Abaqus/CAE and Abaqus/Standard, introduces Python-based scripting and the concepts of Design of Experiment and optimization, and then requires synthesis of all of these into a single final project. Such projects must include multiple parts, at least five design variables and four performance metrics, and include rigorous DOE and optimization studies to arrive at a final best design. Finally, a preconfigured workflow is used to allow students to step “inside” their designs regardless of scale using one of a number of virtual reality – VR – options. 

This talk will review the technical sequence of the course and the impact it has had on students with an interest in solid mechanics, but will focus on highlighting the wide range of impressive analysis and design studies that students have completed – including a diversity of wings, morphing rotor blades, rocket assemblies, astronaut gloves, and even surfboards - many of them rivaling the work performed in many companies. Finally, the role of immersive VR visualization in increasing student understanding and excitement will be demonstrated.

Sharpening the Pencil on Live Loads: A Design Story

Abstract:

Thread analysis is a critical structural analysis for downhole applications in the oil and gas industry, where strength and sealing performance of the thread connection is evaluated under the design load envelope. The first step of thread analysis is to model the pre-stressing effects caused by the initial make-up-torque. This modelling is typically done by applying an interference fit in 2D axisymmetric simulations using the well-known power-screw equation. However, interference calculations become challenging if the thread design and geometry are not conventional, such as double-shoulder threads, because the power-screw equation is no longer applicable. The goal of this paper is to establish a general method to numerically calculate the interference fit applicable to both single-shoulder and double-shoulder threads using 2D axisymmetric models. The torque mechanisms of single-shoulder and double-shoulder threads are first compared, and then a new equation is developed to extend the application of power-screw equation to double-shoulder threads. Full 3D simulations followed by 2D axisymmetric finite element analyses are conducted to better understand the mechanics of the problem and verify the proposed method. The analysis results confirm the substantial difference in mechanics of the single-shoulder and double-shoulder threads and the way torque-induced axial force is distributed. Finite element analyses reveal the high fidelity of the proposed methodology, where the results of 3D and 2D simulations as well as the predictions of the proposed equation come into good agreement. The results of this study can substantially improve the make-up torque simulation of threads using 2D axisymmetric models.
