The latest version of DNV Sesam, as of available information, introduces several advanced features aimed at enhancing efficiency, accuracy, and usability for offshore and maritime structural engineering. Below is an overview of the key features and improvements based on recent updates:
Key Features of the Latest Sesam Version
Enhanced Cloud Computing with Sesam Cloud Compute:
Enables thousands of parallel simulations in the cloud, significantly reducing analysis time from days or weeks to a few hours. This is particularly beneficial for offshore wind structure design, allowing engineers to focus on model optimization rather than waiting for results.
Improved Eccentricity Modeling:
Simplifies modeling of eccentric members by eliminating manual recalculations. Changes to eccentric or segmented members are automatically updated, reducing tedious work and saving time, especially for complex offshore jacket structures with hundreds of beams.
Advanced Wind Load Analysis in Sesam GeniE:
Automatically recalculates wind loads, including suction effects, when wind strength or direction changes. This is critical for assessing loads on large equipment and living quarters on jackets, improving accuracy and reducing analysis time.
Expanded Code Checking for Jackets:
Allows users to define code-checking details directly on the structure, not just on capacity members. This enhances flexibility and precision in strength assessments, particularly for jackets, ensuring compliance with DNV Rules and Common Structural Rules.
Model Import from Other CAE Tools:
Supports seamless import of models from tools like SACS, StaadPro, Ansys, and Nastran, as well as older Sesam versions. This reduces remodeling efforts, simplifies modification and requalification projects, and leverages Sesam GeniE’s advanced graphic and modeling capabilities.
Tension/Compression and Wave Load Analysis:
Includes improved tension/compression analysis and the ability to calculate wave loads underwater, enhancing the accuracy of hydrodynamic assessments for fixed and floating structures.
Sesam Manager Enhancements:
The latest Sesam Manager (version 6.2) provides a unified environment for creating and executing analysis workflows based on best practices. It integrates various Sesam modules and external applications, streamlining project management.
Support for Offshore Wind Applications:
Tailored features for fixed and floating offshore wind structures, including time-domain and frequency-domain analysis workflows. These optimize the design of wind turbine support structures, ensuring safety and longevity under extreme weather conditions.
Earthquake Design and Pile Code Checking:
Supports earthquake design of tubular joints per API 21st and 22nd editions, crucial for regions like Asia. Additionally, pile code checking enhances the reliability of foundation designs.
Section Stiffness Editing:
Allows users to modify section stiffness, supporting design, operation, and life extension of newbuilds and existing assets.
Integration with MSC Apex:
Through a partnership with MSC Software, Sesam integrates with MSC Apex as a CAD-to-CAE translator, streamlining workflows and reducing design and verification time by weeks. This enhances productivity for maritime and offshore engineering tasks.
