Vessels must have sufficient stability in order to sail safely. Vessels need to provide necessary stability criteria during entire voyage. First international stability regulations have been applied to vessels in 1968. The criteria proposed within these regulations are recommended to the vessels over 100 meters by IMO (International Maritime Organization). The criteria in the proposal have not considered any dynamic effects. Hence, IMO constituted weather criteria in 1985. IMO first constituted the previously applied stability criteria in 1993, and afterwards collected the current stability regulations under the IS CODE headline in 2008. In spite of all applied stability criteria, vessels those capsized lead IMO to consider new regulations. These potential regulations are mostly about dynamic effects that vessels are exposed to. Since 2005, subcommittee of IMO, SLF (Stability, Loading Lines and Safety of Fishing Vessels) has started to study over Second Generation Intact Stability Criteria. SLF subcommittee has stated the primary mode of stability failures, which is parametric roll, pure loss of stability and broaching. In this paper, the primary mode of parametric roll, which is Level 1 Vulnerability Criteria, was evaluated and the criteria was applied for a selected midsize container ship. The criteria gave the same results with the ABS Susceptibility Criteria.
