EMSA finalises third passenger ship safety study

摘要

A consortium coordinated by DNV GL has recently finalised a study on the damage stability of passenger ships. This is the third study on this topic funded by the European Maritime Safety Agency (EMSA). The research work has led to recommendations for updated requirements, new software tools and new knowledge of the risks from watertight doors and grounding. The final output from the work has also been forwarded to the IMO Sub-Committee on Ship Design and Construction (SDC) for further consideration. The probabilistic concept of damage stability was made applicable to cargo ships by the 1990 Amendments to the SOLAS Convention. The probabilistic concept implies that a factor A (Attained Subdivision Index), which is the weighted sum of the probabilities of damage occurring (p-factor) multiplied by the respective probability of survival (s-factor), shall be bigger than the target value R (Required Subdivision Index). A = Σ p * s ≥ R.
