DEVELOPMENT OF CAD BASED STABILITY CALCULATION SOFTWARE FOR PURE-LOSS OF STABILITY AND PARAMETRIC ROLLING FAILURE MODE OF 2ND GENERATION INTACT STABILITY CRITERIA

Abstract

Although the IMO mandates IS Code Part A to build and operate ships, ship safety is not guaranteed due to the problem of dynamic stability. So, IMO prepared the second-generation stability standard with five modes. However, since the software supporting the second-generation stability calculation is insufficient, CAD-based stability calculation SW that supports the second-generation stability calculation was developed. And in this paper, we calculated the change in resilience by waves, and calculated the restoration performance in Pure-Loss of Stability and Parametric Rolling Failure Mode.
