Common Structural Rules Software (CSRS) has released a software upgrade that simplifies compliance with current and pending International Association of Classification Societies (IACS) Common Structural Rules (CSR).

(CSRS) is a joint venture company established by American Bureau of Shipping (ABS) and Lloyd's Register (LR) to provide industry with a validated and verified suite of software tools for CSR.

“As requirements change, it is imperative for classification societies to provide services and solutions that keep pace. By updating this software, we ensure our tools are effective and provide the most help to end users,” says ABS Chairman, President and CEO Christopher J. Wiernicki.

Improvements to this leading software facilitate compliance to existing and future IACS Common Structural Rules, providing users with an easy way to evaluate designs.

Developed from the technical strengths of LR and ABS, version 2.5 of the CSR Prescriptive Analysis and CSR Finite Element (FE) Analysis software allow 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 July 1, 2015, as well as for the rule changes that come into force on July 1, 2017.

Both class societies will use these tools to evaluate new designs against the CSR.The updated CSR Prescriptive Analysis software requires only that the user input the appropriate data. All of the outputs are clear, straightforward and easy to read. A summary report provides required and offered scantlings with graphic representation of any deficiencies.

An intermediate report summarizes dominant criteria for each structure and a detailed report provides data for every parameter value. In conjunction with CSR FE Analysis, this complete tool makes verifying compliance with CSR possible with minimal effort.

The software, which was licensed to nearly 500 users prior to the production release, is now being employed by nearly 1,000 users. Regular updates for additional structural coverage and functionality will address ongoing CSR changes.
