Version 2.5 of the CSR Prescriptive Analysis and the new CSR Finite Element (FE) Analysis software, allow assessment of whole vessel structures, including new oil tanker designs. Both class societies will use these new tools to evaluate new designs to the CSR.
"I am pleased that the strategy laid out more than a decade ago is achieving our objectives," said LR’s marine director, Tom Boardley. "Following the development of the CSR in 2005, LR and ABS quickly realised that only common software would support the industry desire for common scantlings, and our CSR Software tools had become widely used.
“With the introduction of the new Common Structural Rules, we have developed a completely new generation of CSR software that will enable shipbuilders and shipowners to easily and consistently address the requirements of the new IACS Rules," he said.
"This software constitutes a new industry standard," said ABS chairman, president and CEO Christopher Wiernicki. "In our collaboration as two of the world’s leading class societies, we continue to achieve our primary objective to enable the advancement of the maritime industry through reliable and dependable software applications."
The software requires only that the user input the appropriate data. All of the outputs are clear, straightforward and easy to read, the class societies claimed. A summary report provides required and offered scantlings with graphic representation of any deficiencies.
An intermediate report summarises dominate criteria for each structure and a detailed report provides data for every parameter value. In conjunction with CSR FE Analysis, this complete tool makes verifying compliance with CSR possible with minimal effort.
Nearly 500 licenses were issued prior to the production release and it will be followed with regular updates for additional structural coverage and functionality and to address ongoing CSR changes.
Detailed information on structural areas and functionality covered by this release can be found in the release notes and user guide bundled with the software installation.
In response to the latest amendments to the IACS CSR for bulkers and tankers, ClassNK has just released its latest version, PrimeShip-HULL(HCSR) Ver 3.0.0.
Although they represent a major step forward for ship safety, they also present a number of new challenges for shipyards and designers, due largely to the increase in overall vessel design time.
To alleviate the burden of these new rules on ship designers and cut down the required man hours, ClassNK released PrimeShip-HULL(HCSR), a multi-functional vessel design support tool that makes it easy for designers to carry out rule calculations and optimise their designs.
The new version builds on the success of ClassNK’s existing system, which to date, more than 800 licenses have been provided to over 90 shipyards.
It is up to speed with all the latest rules and is fully compliant with the February, 2016 corrections (Corrigenda 1) made to CSR.
