It is a comprehensive and consistent rule set which will set the standard for oil tankers and bulk carriers. The new rule set consists of two main parts: The first is a common part covering general hull requirements applicable to both ship types, such as wave loads, hull girder strength, buckling and fatigue requirements. The second part covers ship-type specific requirements only applicable to bulk carriers or oil tankers. The rule application has not changed from CSR-OT and CSR-BC. The rules will also comply with SOLAS II-1 Regulation 3-10 “Goal-based ship construction standards for bulk carriers and oil tankers” (GBS).

For which vessel types and sizes is the CSR BC & OT applicable?

CSR BC & OT applies to:

• Tankers for oil and oil product, with length 150m or above
• Bulk carriers with length of 90m or above

Excluded by the CSR are: Ore carriers, open hatch bulk carriers without hopper and top side tanks, OBOs, self-unloaders and some other specialized bulk carriers

Key features of the CSR BC & OT compared to CSR-OT and CSR-BC

• Extended verification scope, including FE analysis of all cargo holds
• More transparent and consistent requirements, including technical background
• Improved load model/formulations based on direct wave load analysis
• Enhanced fatigue standard, including detail design standard
• Hull girder buckling, also including lateral pressure and the combination with shear stress
• Hull girder ultimate limit state assessment, including damaged condition
• Compliance with IMO Goal Based Standards (GBS)
• Increased design grab weight for Panamax and Capesize vessels (Applicable only for Bulk Carriers)
