Software for CSR-BC and CSR-OT
ClassNK has developed and released advanced calculation software called "Primeship-HULL (CSR)" for the Common Structural Rules for Bulk Carriers (CSR-BC) and Common Structural Rules for Double Hull Oil Tankers (CSR-OT).
On this page you will find a summary of the software, the software's hardware requirements, and information on how to apply for the software.
PrimeShip-HULL(CSR) users can gain access the user support site, which offers beneficial information for users, such as updates, FAQs, bug information, etc. Please use the user ID and password assigned to your software to login.
The rule calculation systems provide the necessary information and report outputs for CSR-BC and CSR-OT application. The rule calculation systems can provide you with cross section calculations, hull girder strength assessments, local strength assessments, fatigue strength assessments and buckling strength assessments, etc. based upon inputs of arrangements and gross scantlings for cross sections as shown below in figure on the left.
Direct Strength Analysis
The direct strength calculation tool can conduct Finite Element Analysis (FEA) and provide strength assessments as shown below in the figure on the right. The system is based upon MSC.Patran and it strongly supports structural assessment work by providing design loads, boundary conditions, etc. in accordance with the requirements of the CSR-BC and CSR-OT so that a series of direct strength analyses can be performed.
