Abstract [en]

Intact stability describes a ship's stability in waves to avoid incidents. Operational safety measures are an important aspect of a holistic safety approach for intact stability. The aim of this study is to provide a structure of the relationship between key elements of the intact stability risk concept. Such a structure has implications for risk assessment and risk management. The developed structure is discussed in relation to the proposed second generation intact stability criteria, which highlights how the measures relate to safety. The definitions are also analyzed in relation to seven incidents. Operational decisions and the human element are shown to have strong ties to exposure, vulnerability and recoverability. However, the results herein show that the interdependency between risk and operational decisions differ between the three areas; the effective measures are thus different. The actual exposure, vulnerability and recoverability for a ship is not known nor can it be fully assessed. However, all three aspects of intact stability safety must be considered in a structured manner to reach a cost effective intact stability.
