The IACS harmonised CSR will be applied to tankers over 150m and bulk carriers over 90m contracted after July 1 2015. The rules will demand deeper structural analysis at the design stage, including FEM analyses of cargo hold structures, and new criteria to enhance safety and reliability.
The Japanese classification society claims the updated software system is the first to reflect the new rules, and will facilitate ship design based on the latest prescriptive and direct strength calculation requirements.
ClassNK says version 2.0.0 of PrimeShip-HULL(HCSR) will also feature improved data linkage with commercial CAD software such as NAPA Steel, as well as improved modelling and calculation functions.
In December 2014, ClassNK announced a project with Finnish software provider NAPA to integrate both companies’ respective shipbuilding software in an effort to eliminate duplication of work and improve the design process.
