The introduction of the IACS Common Structural Rules for Bulk Carriers and Oil Tankers (CSR BC & OT) mean advanced rule calculation tools are more important than ever for designers and yards.
Whilst this will give a better picture of how a design will perform in reality, it can be a time consuming and extensive process without automated tools to assist.
DNV GL have announced that they have addressed this issue with the latest release of DNV GL’s integrated calculation tools Nauticus Hull and Sesam GeniE.
Designers will now need to work with an increased number of models and load cases.
There are therefore significant gains to be had from a streamlined and efficient design iteration process.
The newest versions offer increased calculation speed and efficiency in design, CSR BC & OT rule calculations and the approval process.
A newly developed FE fatigue tool 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.
Whilst load application has been improved by integrating the adjustment of hull girder loads.
Additionally, the graphical display and reporting of loads have been improved to support model verification and the large number of load cases.
“Advanced software tools will continue to grow in importance in the future, with the increasing emphasis on making more realistic determinations of loads and structural strength” says Erik Ian von Hall, Head of Product Centre at DNV GL – Software.
