At the International Maritime Organization (IMO) the new generation intact stability criteria is now under development. This paper describes a current status of this development for facilitating discussion among experts in stability research. It was already agreed to consist of 3 levelled criteria and onboard operational guidances for four different stability failure modes, which include pure loss of stability, parametric rolling, broaching and stability under dead ship condition. Member states submitted available methodologies with sample calculation results so far but the first level criteria for pure loss of stability and parametric rolling are still missing and the first level criterion for broaching is required to be further upgraded. More verification and validation are essential for finalising this criterion set.

Abstract
At the International Maritime Organization (IMO) the new generation intact stability criteria is now under development. This paper describes a current status of this development for facilitating discussion among experts in stability research. It was already agreed to consist of 3 levelled criteria and onboard operational guidances for four different stability failure modes, which include pure loss of stability, parametric rolling, broaching and stability under dead ship condition. Member states submitted available methodologies with sample calculation results so far but the first level criteria for pure loss of stability and parametric rolling are still missing and the first level criterion for broaching is required to be further upgraded. More verification and validation are essential for finalising this criterion set.Pubblicazioni consigliate
