Abstract

A new formulation for the assessment of ship's survivability in damaged condition, based on the probabilistic concept, was developed in the framework of the EU-funded research project named GOALDS. The investigation of the impact of the new formulation on the design and operational characteristics of cruise ships is the main objective of the present paper. An additional objective is to investigate the possibility of raising the required subdivision index compared to current SOLAS 2009 levels; this is supported by demonstrating the feasibility of representative sample ship designs of enhanced survivability through formalized, multi-objective optimization studies, while considering a risk and cost effectiveness analysis.
