IR-CSR Software

Common Structural Rules are applicable for self-propelled bulk carriers and double hull oil tankers with unrestricted navigation. Ships contracted for construction on or after 1st July, 2015 must comply with Common Structural Rules. The CSR Rules aim at analyzing the structural response of the ship to Yield, Fatigue and Buckling Loads and prescribe minimum compliance parameters.

The IR-CSR software has been designed with an intuitive graphical user interface featuring

2d modeler

Finite element modeler

Global strength analysis

Local scantling analysis

Direct strength analysis

Prescriptive Assessment is carried out for individual sections based on Panel Approach. Static and Dynamic Loads based on formulae provided in the Rule Text are used for Analysis. Prescriptive Assessment includes Yield, Buckling and Fatigue Checks. Provisions for CAD modeling of 2D Ship Sections are provided in the software.

The main features are:

Section Modeling

Compartment Attachment

Section Modulus Calculations

Global Strength Assessment

Local Scantlings VerificationThe main features are:

Direct Strength Analysis is to be carried out using Finite Element Method. 3 holds of the Vessel are analyzed at a time. Pre-processing is done using a customized version of MSC Patranand MSCNastran is used as the solver.

The features below have been automated:
