ClassNK Releases New Container Guidelines/Software

October 4, 2011

ClassNK Releases New Guidelines and Software for Container Carrier Structures.


ClassNK has released a new revised edition of its “Guidelines for Container Carrier Structures – Guidelines for Direct Strength Analysis”, as well as a new version of its PrimeShip-HULL(DSA) software for use in designing container carriers in line with the new guidelines.


ClassNK released the first edition of its “Guidelines for Container Carrier Structures” in 2003, providing shipbuilders and designers with a wealth of information on ship performance that the Society had accumulated over its many years in ship classification, as well as the latest information on new technologies and other advances related to container carrier construction. In the years since that first release, however, technological advances have made it possible for larger and more advanced container carriers to be developed, and ClassNK began to review and update its Guidelines in order to address these changes and incorporate the latest container carrier design philosophies.


The release of the “Guidelines for Direct Strength Analysis (Revised Edition)” mark the completion of the first phase of this project and provide updated information on carrying out Direct Strength Analysis of container carriers. The new Guidelines are available free of charge for use by shipyards and designers and can be downloaded from the ClassNK website at the following address:


As part of the second phase of this project, ClassNK is currently reviewing and updating the contents of its “Guidelines for Hull Girder Torsional Strength Assessment” and “Guidelines for Fatigue Strength Assessment” and plans to release revised versions of each of these guidelines in the near future.In addition to the new guidelines, ClassNK has also released version 2.0 of its direct strength assessment software for container carriers,   PrimeShip-HULL(DSA)/Guideline for Containers.


PrimeShip-HULL(DSA)/Guideline for Containers (Ver.2.0.0) is software designed to perform the direct calculations defined in the revised Guidelines. Using an FE model, users can easily execute complicated FEM analyses through the use of special features such as the automatic identification of structural members and compartments. This revised version of the software not only incorporates all of the revisions of the new guidelines, it also includes a handy user assistance function to guide users through the entire operation process.


This software is provided free of charge to shipyards and designers who plan to perform structural assessments based on the Guideline. Applications for the software should be made to the ClassNK Hull Department
