CC2.5/10 is the seismic design code outlined in the International Maritime Organization (IMO)'s International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code). This code is used for the design of vessels to limit loss of life, minimize environmental damage, and prevent collapse of ships when transporting hazardous substances in bulk.
CC2.5/10 part of the IMO's IBC Code describes seismic parameters to be taken into consideration when designing or constructing a ship that is intended to transport dangerous chemicals in bulk. This includes specific measures such as considering seismic sources, local seismic hazard, site specific soil properties, and dynamic response to seismic motion. CC2.5/10 also prescribes seismic criteria for ship hull girder strength, integrity of system components, arrangement of hold-opening, strengthening of stiffeners, and the choice of construction materials.
