DNV Software is pleased to announce the release of Nauticus Hull January 2009. Building further on the successful January 2008 version with enhancements such as import of hull form and import of relative deflections for fatigue analysis of bulk carriers the release confirm the position of Nauticus Hull as the leading software for hull strength calculations.

The new release has been in production in DNV Maritime since the 4th of March and the DVD is currently being distributed to our customers. It is also available for download at the Nauticus downloads and update site.

Some of the improvements are:

• Import of hull form
• Support for the IACS unified requirements for polar ships
• Import of relative deflections from FE analysis for fatigue calculation of longitudinals according to the CSR Bulk rules
• GeniE template for 1A1 loads

The new hull form import makes modelling of cross sections faster as the frame profile can be extracted at any position along the hull and serve as basis for modelling of cross sections. The hull form import support the most common dxf formats and also have a built in scaling functionality and export of lines to HydroD.

Another important update that improves work efficiency is the import of relative displacements from finite element analysis for fatigue strength calculations of stiffener end connections at transverse bulkheads for CSR Bulk. Nauticus Hull for CSR Bulk with GeniE as the tool for direct strength assessment is the most comprehensive and efficient calculation package in the market today. With GeniE all the information needed to perform direct strength calculations as defined by the class rules is gathered in one concept model including gross scantlings, corrosion additions, compartment data, loads and categorisation of structural members. By keeping all information in one model, the scantling iteration and redesign capabilities in GeniE are unique. Combined with the strong 3D modelling environment in GeniE, finite element analysis can be performed faster than ever.

In the January 2009 release of Nauticus Hull the GeniE template is also made available for finite element analysis according to the DNV 1A1 rules, and it is planned to complete the GeniE interface with a template for CSR Tank by the end of 2009. “As in the offshore market we want to position GeniE as the obvious choice for all aspects of finite element analysis in the maritime industry”, says Nauticus Product Manager Torbjørn Lindemark. “GeniE is a generic finite element analysis tool and can be used for any finite element analysis purpose. With it’s strength on fast modelling and the ease of making changes in the model, GeniE is by far the best tool for finite element analysis during the design phase.”
