ClassNK container carrier design software updated

ClassNK has released the latest version of PrimeShip-HULL for Container Carriers, its structural design support software for container ships.

{mprestriction ids="1,2"}The application consists of prescriptive calculation software and direct strength assessment functionality.

The prescriptive calculation software enables designers to perform assessments for structural strength requirements such as yield strength and fatigue strength assessments, as specified in ClassNK’s Rules for the Survey and Construction of Steel Ships, in addition to longitudinal strength requirements as specified by IACS.

It also features a function to create a model of transverse members as well as longitudinal members, and a function to assess the outside of the cylindrical part of the hull structure, including the fore and aft parts.

The direct strength assessment software has an additional function for torsional strength assessment of the hull. ClassNK amended its rules for torsional strength based on new research results in June 2017.

Torsional strength assessments can be performed by superimposing stress components generated by working hull girder loads on an FE model of an entire ship.{/mprestriction}
