Common Structural Rules Software (CSRS), a joint venture company formed by ABS and Lloyd’s Register (LR), has released updates with new functionality added to both the Prescriptive Analysis (PA) and FE Analysis (FEA) applications.

“We have worked together with Lloyd’s Register and the CSRS Team to ensure our tools continue to evolve and meet the needs of our clients, keeping pace with technological developments in the maritime and offshore industries.  This latest release offers many new advantages over earlier versions,” said Patrick Ryan, ABS SVP, Engineering and Technology.

Nick Brown, LR Marine and Offshore Director, said: “LR and ABS’s partnership continues to improve functionality, integration and modularity of the CSR Software to ensure that we provide the best tools for the industry to use when applying Common Structural Rules.”

CSR PA now allows users to directly import the NAPA cross sectional structural data. Using this feature, users can quickly create new ship models using an existing NAPA model. PA also now includes features to model multiple small openings within transverse primary supporting members. The transverse assessment will take into consideration these openings while performing various calculations.

FEA software is now capable of carrying out local model analysis. This feature allows a fine mesh model to be built outside of the global model so that multiple engineers may work on a design simultaneously.

The software has been cross-checked by IACS and both software products: CSR Prescriptive Analysis and CSR Finite Element (FE) Analysis, demonstrated very high accuracy compared to other software. Improvements to this software facilitate compliance to IACS Common Structural Rules (CSR), providing users with an easy way to evaluate designs. Developed from the technical strengths of LR and ABS, the CSR Prescriptive Analysis and CSR Finite Element (FE) Analysis software is now employed by over 600 users and growing every day. Regular updates will continue to improve functionality and address rule changes.
