Integration Of Safety Studies Into A Detailed Design Phase For A Navy Ship

A. Fulfaro & F. Testa
The latest generation of Italian Navy ships has moved a giant step forward in the approach to the main relevant transwarship activities which have an impact on all the design phases and at the whole warship level. Among all the activities developed, the safety topics have been implemented more and more, shifting from prescriptions essentially based on past experience to goals based on risk considerations, that were included in the scope of the contractual specifications. In its supplier role, Fincantieri for the first time has been challenged with the requirement of demonstrating the vessel safety by means of risk assessment studies during the developed design phases. The studies followed a twofold stream of activities, that is, analysis of the ship’s systems (including Platform and Combat System) and analysis of the health and safety of the persons onboard. The safety analysis was essentially based on the study of some contractual hazards already selected by the Client. By means of the typical risk assessment tools (such as Fault Tree Analysis), properly injected as far as possible with Navy operating experience, a level of probability and severity was associated to each hazard, a risk matrix was constructed and the results checked against the Navy acceptance criteria. The process has been completed with the integration of the main safety requirements into the design. The aim of the present paper is to give an overview of the process. Keywords: transwarship, safety cases, design measures, requirements, hazard, risk analysis, fire propagation, preliminary, final, navy, military ship.
