Common Structural Rules Software Update

New features enable swift compliance evaluation for both current and upcoming CSR requirements

Common Structural Rules Software LLC, a joint venture company formed by LR and ABS, has released an update that simplifies compliance with current and pending IACS Common Structural Rules (CSR). 

The software provides users with an easy way to evaluate designs, enabling assessment of whole vessel structures. It consists of two applications – the CSR Prescriptive Analysis (PA) application, which is used to assess HullGirder Ultimate Strength and Hull Local Scantling on different tanker and bulk carrier structures, and the CSR FE Analysis tool, which uses a Finite Element Analysis (FEA) approach for strength and fatigue assessment of different tanker and bulk carrier structures.

The new updated PA and FEA releases have multi-rule year capability, which allows users to evaluate ships for both 2017 and 2015 IACS rules – the 2017 IACS rules will become effective on 1 July 2017.  

“The Common Structural Rules provide the only industry route to compliance with IMO’s Goal-Based Standards for tanker and bulk carrier structures,” commented LR’s Marine and Offshore 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 in use by almost 1,000 users. Regular updates for additional structural coverage and functionality will address ongoing CSR changes.

Detailed information on structural areas and functionality covered by this release can be found in the Release Notes and User Guide bundled with the software installation. The updated CSR Prescriptive Analysis and CSR FE Analysis are available for download from the Common Structural Rules Software LLC website at www.commonstructuralsrulessoftware.com
