This study deals with the recently finalized and decidedly possible candidate of state-of-the-art intact
stability criteria for ships; namely second generation intact stability criteria of International Maritime
Organization, IMO. As a United Nation’s agency, IMO is responsible for regulating ship design,
construction, operation and safety internationally through its adopted rules and regulations. The
above-mentioned criteria have been on the agenda of the organization for about 20 years. It is
undoubtedly will be a breakthrough in ship stability when put in effect very soon. Basically, the
criteria are based on purely dynamic behavior of ship motions and candidate to supersede the existing
statical criteria. This study details key points of the criteria starting from the genesis until the last
form referring to the foundation of each failure modes of motion. A brief summary of the comparison
with the existing criteria is also made. Possible impact of the criteria on ship design and safety is
evaluated addressing the strong and weak points. Finally, a few examples on the application of the
new criteria is provided on different ship types for the purpose of early validation.
