Japan-based ship classification society ClassNK has unveiled a new version of its design support software, PrimeShip-HULL (HCSR) Ver.3.5.0.

The software has been designed in response to the IACS common structural rules for bulk carriers and oil tankers (CSR BC & OT).

The new HCSR version has been designed to provide better overall performance and usability, as well as help the users in designing safer ships in compliance with CSR BC & OT.

"The bottom slamming function uses FE models for the hold analysis required."

Besides, the calculation software has cut the time required for calculations and improved user interface performance, and has added more functions including an evaluation function for bottom slamming.

The bottom slamming function uses FE models for the hold analysis required, and features automatic creation functions for evaluation panels, slamming loads and reports.

It also includes an improved manhole modelling function, batch edit for multiple opening information and registering function for screening evaluation points.

The updated version, which has been offered free of charge to the industry, helps designers to perform rule calculations in line with the CSR BC & OT and optimise their designs.

Designed to improve user interface performance, the latest HCSR version has been developed on the basis of ClassNK’s existing software.

Additionally, its initial design function can now be used for structural arrangements such as engine rooms, in addition to the cargo hold region of the ship.

Till February, ClassNK provided over 800 HCSR software licenses to more than 90 shipyards.
