IACS common structural rules

On 14 December 2005 the Common Structural Rules for Tankers and Bulk Carriers were unanimously adopted by the IACS Council for implementation on 1 April 2006. The Council was satisfied that the new rules have been based on sound technical grounds, and achieve the goals of more robust and safer ships.

IACS now implements the CSR maintenance program (IACS Procedural Requirement No.32) via the IACS CSR Knowledge Centre (KC). All the agreed Q&As and CIs (Common Interpretations) are published on the IACS web site without delay in order to assist its Member Societies and Industry in implementing the CSR in a uniform and consistent manner.

IACS has also put in place a long-term plan to further increase the harmonisation between the Tanker and Bulk Carrier rule sets.
