{mprestriction ids="1,2"}Version 2.5 of the CSR Prescriptive Analysis and CSR Finite Element (FE) Analysis software allows assessment of whole vessel structures – including new bulk carrier and oil tanker designs – using compliance information for the current CSR, which entered into force on 1 July 2015, as well as for the rule changes that come into force on 1 July 2018. Both class societies will use these tools to evaluate new designs against the CSR.

The updated CSR Prescriptive Analysis software can be used on both Windows 7 and Windows 10, and offers summary reports providing required and offered scantlings with a graphic representation of deficiencies. The reports summarise dominant criteria for each structure as well as data for every parameter value.

A new user interface for the CSR FE Analysis software has been added to enable automatic picking or manual selection to display the stress readout point for Cruciform Flange, Cruciform Web and Bracket Toe hotspots. Results are added to verification results for Fatigue Assessment.

“The Common Structural Rules provide the only industry route to compliance with IMO’s Goal-Based Standards for tanker and bulk carrier structures,” said LR Marine and Offshore Business director, Nick Brown.

“By working together, LR and ABS have provided fully up-to-date straightforward and accessible tools for the whole industry to use when applying CSR.”

The software is currently employed by approximately 1,600 users, with the updated CSR Prescriptive Analysis and CSR FE Analysis modules available for download from the Common Structural Rules Software LLC website.{/mprestriction}
