Core features of PSE® Offshore Structural Analysis software
A structural analysis software for Oil&Gas professional engineers.
Compliance with the API 5th Edition
PSE Petroleum Structural Engineering® software is based on the API 4F (5th edition) Specification for Drilling and Well Servicing Structures.
Wind loads, based on the velocity component approach, and vessel dynamic motions are defined according to API 4F Specification for Drilling and Well Servicing Structures. PSE® systematically incorporates the latest requirements and recommendations for suitable steel structures for drilling and well servicing operations for the Oil&Gas industry.
PSE® software is an innovative solution aiming to increase productivity of international companies helping them to achieve the most complex structural engineering projects.
Automatic wind wall calculation
Wind loads, calculated using the velocity component approach, are defined according to the API 4F Specification for Drilling and Well Servicing Structures (5th edition).
PSE® includes a specialized tool for generating wind and ice loads on open structures, such as drilling rigs. This feature enables automated calculation of wind and ice loads on each structural element.
PSE® software streamlines wind load application by computing loads based on projected area, projected pressures, or velocity components. It offers a range of wind profiles and automatically determines shape coefficients (drag factors) for accurate load estimation.
Automated Calculation of Member Unbraced Lengths
PSE® automatically determines unbraced lengths for structural members, ensuring accurate stability analysis. This feature optimizes design efficiency by eliminating manual calculations and improving reliability in load-bearing assessments.
Robust and comprehensive structural analysis
PSE® features comprehensive state-of-the-art structural analysis methods, including:
• Finite Elements Analysis (FEA) including plates and shell elements
• P-Delta Analysis, Linear and Nonlinear Analysis, Buckling Analysis
• Static Equivalent Seismic Analysis, Seismic and Dynamic Time-History Analysis
• Non-linear analysis using load control and displacement control strategy
• Linear and exact non-linear cable elements
• Direct Analysis Method (DAM) and the Effective Length Method (kL) for AISC 360
• Possibility to add non-structural components using Spatial Objects and Spatial Loads to automatically calculate dead, ice, and wind loads
Structural insights animation
PSE® allows to animate analysis results, including static, P-Delta, buckling, seismic, and dynamic analyses. This visualization highlights displacements, internal forces, stresses, reactions, mode shapes, and time-history data, offering clear insights into structural behavior.
Animating envelopes focuses on critical regions, simplifying complex data for better decision-making during dynamic events.
Vessel Dynamic Motions
PSE® integrates advanced vessel dynamic motion analysis, adhering to the API 4F (5th edition) Specification for Drilling and Well Servicing Structures.
• Accurate inertial force calculation: Accounts for vessel dynamic motions and the impact of radial, tangential, and translational forces from mass acceleration.
• Comprehensive motion simulation: Models roll, pitch, and yaw rotations along with heave, sway, and surge translations, ensuring precise structural response analysis.
• Optimized for offshore environments: Designed for offshore drilling structures on vessels, semisubmersibles, and floating hulls, enhancing design reliability and safety.
Wave and Current Loads
PSE® provides advanced analysis of wave and current loads on submerged structural members in platforms and floating hulls, following API RP 2A specifications.
• Comprehensive load analysis: Accurately computes wave and current forces acting on structural members.
• Linear & nonlinear kinematics: Supports Airy’s linear theory and Fenton’s nonlinear theory for precise wave kinematics modeling.
• Optimized for offshore structures: Ensures stability and performance of submerged components in dynamic marine environments.
Executive custom reporting - editable professional reports
PSE® software offers advanced custom reporting tools, enabling users to create tailored, professional reports with ease. With options to select relevant data, add individual or multiple tables, and customize settings, users can design layouts that meet specific project needs.
Editable titles, table reordering, and predefined templates enhance efficiency, while saved custom layouts streamline future reporting. Reports can be customized and exported to Microsoft Word and Excel, streamlining workflows.
Intuitive graphical ribbon-based interface
PSE® features an intuitive, ribbon-based graphical user interface powered by DirectX 11 and OpenGL 2.0 for enhanced performance. Users can efficiently create, analyze, and design complex models, visualized as lines, wireframes, or 3D solids.
Users benefit from key functionalities such as detailed element creation, and transparency options for components like members, plates, surfaces, spatial objects and panels.
Additionally, powerful edition features allow to model very complex and non-standards towers. The software supports metric, imperial, and mixed unit systems, which can be modified at any time.
PSE® Software Reviews
