Ship operations take place in hostile and corrosive environments meaning that the structural strength of the ship’s hull may deteriorate with time leading to buckling or structural instability. Buckling has long been recognised as one of the main modes of failure of ship structural elements and IACS has, for many years, had in place a number of Resolutions to address this.
Recognising, however, that the rules for buckling varied across different IACS Unified Requirements (URs), such as S11, S11A, S21, S21A and Common Structural Rules for Bulk Carriers and Oil Tankers (CSR for BC & OT), in 2018 IACS agreed to develop a standalone Unified Requirement (UR) dedicated for Continue reading “IACS adopts new unified requirement on buckling strength assessment of ship structural elements”
