CSR BC & OT requirements
With the new CSR rules, fine mesh modelling of local details and fatigue assessment is extensive and time-consuming without the use of advanced rule calculation tools. DNV GL provides modelling support for FE fatigue models and fatigue assessment for efficient ship structural analysis and design.
The newly developed FE fatigue tool in Nauticus Hull includes methods for adjusting the stress components for element sizes differing from the net thickness, allowing mesh consistency while updating plate thicknesses in design iterations.
