Abstract
In the recent years, the intact stability rule framework witnessed progressive but certain shift towards probabilistic analysis, as already happened in with the damaged stability framework thanks to SOLAS. This paradigm shift is emphasized by introduction of Second Generation Intact Stability criteria (SGISC). This paper implements and renders operational techniques, procedures and indications presented in Direct Stability Assessment (DSA) within SGISC, with a particular focus on pre-process of input data for the assessment, post-process of output data using direct counting method and results presentation. The parametric resonance in following and heading irregular sea stability failure mode has been studied using analysis of probability of failure direct counting procedure for the C11 containership. Besides, a sensitivity analysis on relevant design parameters has been undertaken. The post-processing outcomes have been presented and comments about the expected future role of the DSA are given.
