Classification society ClassNK has released PrimeShip-HULL 2026.1, the latest version of its hull structure assessment software for shipbuilders and design firms.
The update integrates evaluation functions for the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR-B&T) into the platform, which complies with Part C of the Rules for the Survey and Construction of Steel Ships.
Previously, users were required to employ different versions of the software depending on whether they were applying the Part C hull structure rules or CSR-B&T requirements. PrimeShip-HULL 2026.1 introduces a unified interface that can be used consistently across different rule requirements and ship types.
ClassNK launched the new platform in 2022 following a revision of Part C of its rules. Other features of this latest release include automated functions to reduce workloads, and improved data interoperability with 3D CAD systems.
Current users can download the software from the PrimeShip-HULL support site.
