Hull software

ClassNK has released PrimeShip-HULL 2026.1, the latest version of its hull structure assessment software for shipbuilders and design firms. This release integrates the evaluation functions for IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR-B&T) into the new PrimeShip-HULL platform, which is compliant with the Rules for the Survey and Construction of Steel Ships, Part C. Previously, when applying the Rules for the Survey and Construction of Steel Ships, Part C related to hull structure and, when applying the CSR-B&T, it was necessary to use different versions of PrimeShip HULL for each. The new release offers a unified interface that can be used consistently across different rule requirements and ship types.
