Two class societies – ABS and LR – have tried to dispel this idea by jointly establishing Common Structural Rules Software LLC (CSRS) to provide industry with a validated and verified suite of software tools for CSR. However, despite the concept of common rules having been devised to address the issue of individual classification societies competing on lowered standards, there were still many who did not believe that the rules would be applied equally. The rules are applicable to all IACS members and with the advent of the common rules, class societies developed software to check and compare newbuilding designs against the requirements of the rules.
That work was completed in 2013 and the new harmonised common structural rules adopted in December that year took effect in July 2015. Napa worked with Tekes, the Finnish funding agency for innovation, and design agency Idean on Napa Designer.Class societies update CSR software suitesĪlthough the original CSRs were developed separately for oil tankers and bulk carriers by two different working groups, it was soon recognised by IACS that there was a need to harmonise the two sets into a single version. Napa Designer was developed as an interactive 3D modelling interface for ship designers that use a conventional 2D approach. The bottom line is, Voz makes fine harmonies, looks young and attractive, has a good sense of humor, and judging by the number of websites about them, has a legion of appreciative fans!

These include Bureau Veritas’ Mars2000, PrimeShip-Hull from Napa parent company ClassNK, Lloyd’s Register’s RulesCalc as well as DNV GL’s Poseidon and Nauticus Hull programs. With the changes implemented, Napa Steel and Napa Designer can interface with independent rule check software that class societies have recently developed.

The CSR unifies and expands on existing structural rules from the International Association of Classification Societies (IACS).
The updates will eliminate duplication between software systems and reduce the work needed to ensure designs are compliant with the new rules. Napa Steel is used for 3D modelling of ships and Napa Designer is a geometry modelling tool. This should streamline ship design compliance with harmonised common structural rules (CSR) for bulk carriers and oil tankers, which were introduced earlier this year.
Napa Steel and Napa Designer have been updated with improved interfaces with class society software. Napa software analyses ship hull designs Finnish software group Napa has released new versions of its design and shipyard software.
