Release of CSR Structural Assessment Software Version 7.0.0

30 August, 2013 – Leading classification society ClassNK (Chairman and President: Noboru Ueda) has announced the release of the latest versions of IACS Common Structural Rules (CSR) structural assessment software.

The following software packages have been updated:


PrimeShip-HULL(Rules)/CSR is software designed to perform structural
evaluations using the scantling formulae defined in the CSR. This software possesses a number of powerful functions such as user friendly interfaces and result displays. This software can be used for both bulk carriers and tankers.


PrimeShip-HULL(DSA)/CSR is software designed to perform the direct calculations defined in the CSR. Using FE models, users can easily execute complicated FEM analyses through the use of special features like the automatic identification of structural members and compartments. In addition, a function to help user navigate the operation process is also provided.

Both packages have been updated to reflect feedback from the users of the software to include new functions and strengthen existing features to improve usability, and help make design work more efficient. ClassNK is constantly looking for new ways to develop even better user-oriented software in the future.

These software products are provided free of charge to customers planning to perform CSR structural assessments. Please contact our Hull Department or Natural Resources and Energy Department if you wish to apply to use these products.
