CREST CSR-T/BC: Evaluation of ship structures according to IACS common structural rules

The methodologies for structural evaluation of tankers CREST CSR-T and bulk carriers CREST CSR-BC for the new buildings and ships in service has been developed in cooperation with Croatian Register of Shipping (CRS). It includes: (1) modules for the structural model data generation, (2) modules for loading generation, (3) modules for determination of the minimal scantlings, (4) modules for direct calculation of the longitudinal strength, (5) modules for the transverse strength calculation, (6) modules for the data acquisition of the corrosion measurements and the structural model update, (7) modules for the structural safety calculation based on the library of structural safety criteria and permitted stress levels, (8) modules for the graphic presentation of the model, loading, deformations, stresses, safety factors, corrosion data, etc. All modules are based upon relevant IACS Common Structural Rules (CSR). Through cooperation with DRS-C3 Advanced Technology Center (Stevensville, MD, USA) MAESTRO Modeler software is used for the generation of model data compatible for analysis in both CREST CSR-T/BC and MAESTRO software. Practical application and validation of methodology on the example bulk carrier structure is presented.
