Powerful Version of PrimeShip-HULL Design Software from ClassNK

Posted to Powerful Version of PrimeShip-HULL Design Software from ClassNK (by on June 5, 2013

Taking a giant lead in the creation of a new ship designing support software ClassNK is set to give a major boost to ship efficiency

The new version of its PrimeShip-HULL (HCSR) ship design support software is the latest creation by ClassNK that could bring about a sea-change in ship building. Amongst other features this version incorporates the new second draft of the IACS Harmonized Common Structural Rules, or H-CSR, for bulk carriers and oil tankers and is set to redefine the way ship designing takes shape.   

It not only incorporates the latest changes and amendments found in the second draft of H-CSR, but also features a number of new and improved functions to help ship designers evaluate and implement the new standards. This powerful software easily interfaces with and export HCSR calculations to commercial CAD software, among other features that are designed to greatly reduce the amount of time necessary to carry out the direct strength calculations of all the vessel’s cargo holds as required by the H-CSR.  

PrimeShip is the collective name for the technically advanced and reliable systems and services comprising a total ship care system developed and offered by ClassNK and aimed at contributing to ensuring the comprehensive safety of ships throughout their operating lives as well as the prevention of marine pollution. 

Dramatically enhancing the standards of ship building this latest version incorporates the Finite Element Method (FEM) Pre- and Post-processor from Altair Engineering’s HyperWorks software used extensively in the aerospace and automotive industries due to its high-performance meshing functions as well as its solver and construction optimization functions. The method originated from the need to solve complex elasticity and structural analysis problems as in civil and aeronautical engineering.

Calculating the intensity, stress and strain, etc of the myriads of torturous forces that buffet a ship’s hull as the cargo laden vessel makes its way on the high seas through torrential waves, rough weather or storms is more of assumption and conjecture. FEM makes it possible to have more accurate details of these forces and that too the exact location of the hull that would be subjected to where these forces would be coming into play. New tools to automatically generate evaluation reports and other improvements to support functions have also been included to improve usability.

“The biggest advantage of this new version,” says A. V. Pradhan, Regional Manager of Nippon Kaiji Kyokai, ClassNK, “is the optimization of steel usage. That is we avoid putting in steel into the ship’s hull where it is not required and add steel where it is necessary. As a result of this optimization the efficiency of the ship is greatly enhanced.”          

Initially released in July 2012, ClassNK’s PrimeShip-HULL (HCSR) was the world’s first design support software to incorporate the requirements of the new IACS Harmonized Common Structural Rules, and is already used by shipyards and designers in China, Korea, and Japan.

This new version of PrimeShip-HULL (HCSR) also boasts enhanced modelling functions to simplify the creation of detailed hull construction models, as well as more efficiently carry out rule calculations for not only the central section, but also the bow and aft portions of the vessel.
