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

The software provides users with an easy way to evaluate designs. It has been validated by IACS and both software products demonstrated very high accuracy for calculations against comparable software. Both LR and ABS will use these tools to evaluate new designs against the CSR.

CSR PA now provides the flexibility to allow users to directly import the NAPA cross sectional structural data. Using this feature, users can seamlessly 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.

The FEA software is now enhanced to carry out local model analysis. This feature will allow a fine mesh model to be built outside of the global model allowing multiple engineers to work simultaneously on the design. Both the PA and FEA software are also now compatible with the Windows 10 operating systems, as well as Windows 7.

Nick Brown, LR Marine and Offshore Director, commented: “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.”

“We have worked together with Lloyd’s Register and the CSR Software 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 Senior Vice President, Engineering and Technology.

The software is now employed by over 600 users. Regular updates will continue to improve functionality and address rule changes.

Further details can be found in the Release Notes and User Guide bundled with the software installation. The updated CSR Prescriptive Analysis and CSR Finite Element Analysis is available for download from the Common Structural Rules Software LLC website at www.commonstructuralrulessoftware.com.

The Journal

Published every February the journal is now recognised as the highest quality publication that covers all aspects of maritime technology and regulation and a must read for the industry.
