Japanese ship classification society ClassNK has released a new version of its ship design support software PrimeShip-HULL (HCSR).

The newly launched PrimeShip-HULL (HCSR) Ver 4.0.0, is designed to meet the latest amendments made to the International Association of Classification Societies’ (IACS) common structural rules for bulk carriers and oil tankers (CSR BC & OT).

The CSR BC & OT will apply to all vessels contracted for construction on or after 1 July 2017.

ClassNK claim that PrimeShip-HULL (HCSR) Ver 4.0.0 helps fast-track design evaluation and reduces calculation times in the prescriptive calculation software.

The new update was developed based on the existing ClassNK programme, and includes a new function that helps to preview direct strength assessment software reports, improving overall performance and usability.

"PrimeShip-HULL (HCSR) Ver 4.0.0’s new direct strength assessment software features a detailed setting for outputting images when creating reports, extra display options and a preview function."

Calculation times have also been reduced in the prescriptive calculation software included in the new PrimeShip-HULL (HCSR) version, and the initial design function for quick sectional evaluation can now be linked with other sectional data in order to automatically remove longitudinal parameters.

The improved functionality is capable of recalculating the required thickness of structures based on modified parameters of the buckling panel, in order to generate a reinforcement plan for stiffener buckling.
