About the Software:

IRHULL Rule Scantling Calculation Software assists users in verifying the compliance of ship designs against the Rules and Regulations set forth by Indian Register of Shipping. IRHULL supports the design of multiple ship types and also multiple frames of a single ship within the same file. The modeler available within the software assists the User with the creation of transverse sections which can be put through analyses such as Longitudinal Strength, Local Strength, Buckling Strength, Shear Strength etc. The data input by the User is stored in a single file (with extension of .IRClass) which enables easy retrieval of the data for future use and makes handling of large and complex data easier.

Key Features

  • Intuitive Modeler with standard CAD functions
  • Support for multiple Ship Types
  • Panel approach to Scantling checks
  • Global Strength Analyses (Longitudinal Strength and Buckling)
  • Local Strength Analyses (Scantlings, Shear Strength etc.)
  • Execution of all analyses on a single click
  • Customized Tools and Calculators for specific structural elements
  • Analysis Results available in standardized report formats 
  • Efficient data handling
