ClassNK unveils strength assessments software

ClassNK released a new longitudinal strength assessments software “PrimeShip-HULL(Rules)/PartC15”, as part of its prescriptive calculation suite “PrimeShip-HULL(Rules)”.

For ensuring further safety and streamlining structural design of ships, ClassNK issued amendments for Chapter 15, Part C of its Rules for the Survey and Construction of Steel Ships relevant to the longitudinal strength in June 2017. The amendments included clearer standard for transverse members at the buckling strength assessments.

The software has been released corresponding to the latest rule amendments. It enables designers to perform the hull girder bending strength assessments, the hull girder shearing strength assessments and the hull girder buckling strength assessments based upon elastic buckling quickly, as well as the hull girder buckling strength assessments based upon ultimate strength for transverse members and the ultimate strength assessments of cross sections now required by the amended rules.

In addition to the longitudinal strength assessment, the software aims to assist improvements of the efficiency and quality of ship design by its function to model cross sections for any ship types applicable to Part C of ClassNK rules and output the calculation result reports, as Microsoft Word or Excel files.
