11. Decision-support system (Integrated Standard - iSTAND) Monitoring of ship status – Monitoring of sensors / alarms concerning flooding / fire / explosion / – Status of relevant actuators (WT doors, valves, slide doors,, fire fighting, etc.) • Diagnosis / Prognosis – Evaluation of time evolution of ship status (current and forecast) – Evaluation of residual functionality of pertinent critical systems – Evaluation of mustering / abandonment, as appropriate – Evaluation of proposed actions by operator (e.g., compartment sealing, bilge pump activation, boundary cooling and so on) • Advising – Proposed procedure to be followed for the specific emergency and current ship condition, supported by suitable advisory information. – Dynamic evaluation of the proposed procedure based on new ship status and the result of actions taken • Execution and follow-up – Execution of the proposed procedure – Triggering of actions

13. Damage stability & Survivability Parametric subdivision and layout for damage stability and survivability in conceptual ship design Addition of watertight subdivision above freeboard deck.

14. Damage stability & Survivability In order to study the behaviour of the damaged ship in waves we need to produce as detailed a model of it as possible Through time-domain simulations we get information about ship movements and flood water mass and location as well as floating position and ship dynamics.

15. Damage stability & Survivability Visualisation of the test cases can allow us to follow the flood water progress and trace any vulnerabilities in a particular design We can also determine the significant wave height a ship can survive so as to check compliance with damage stability regulations

16. Damage stability & Survivability The process can be verified and enhanced by physical experimenting. Again the models used are highly elaborate and detailed and testing is carried out for various loading conditions and sea states as well as various damage cases.
