Application of CSR

Common Structural Rules (CSR) were adopted by the International Association of Classification Societies (IACS) with the encouragement and assistance of INTERTANKO to ensure that shipyards build and construct tankers to the same minimum structural standards.
This prevents shipyards from building and constructing tankers to lesser, unsafe standards at a reduced cost. CSRs were audited by IMO GBS (Goal-Based Standards) for initial verification and will continue to be audited by IMO for future changes.
The INTERTANKO Secretariat will monitor enforcement of the CSR by the individual IACS members and Port State Control authorities to ensure that a level playing field is maintained for INTERTANKO Members.
The INTERTANKO Secretariat will monitor IMO’s GBS verification audits for IACS CSRs and IACS Members’ responses to the audit findings.
