摘要

From July 2010, new passenger vessels are expected to comply with requirements regarding operability of defined essential systems in given casualty scenarios. Such scenarios include flooding and fire damages, as well as loss of single main vertical zones. Ship systems are extensive and topologically complex; in addition their physical components are intrinsically linked to the watertight and fire-rated boundaries of the vessel's layout. The systems' common dependency on power generation and distribution adds challenges to the problem of verification of their operability when subjected to damages affecting individual spaces or group of spaces, as damage in a space may impact on the functionality and availability of one or more systems in different parts of the vessel. In this paper, a quantitative method for undertaking this assessment at early design stages is presented. The method is a practical application of Binary Decision Diagrams, used to model the functional relationships and dependencies of the physical components of the systems. These dependencies are defined on the basis of the design principles and diagrams of the ship systems, which may vary in detail and resolution, making the assessment possible even at concept design stages. A software tool developed specifically to undertake such assessment during the design process will be demonstrated along with a case study and general observations made from recent applications.
