The project FLOODSTAND presents two main objectives with eight sub-objectives:
a) to increase the reliability of flooding simulation tools in design and onboard use by establishing modeling principles and uncertainty bounds, in particular:
- by establishing new experimental and computational data and guidelines for modeling leakage through closed doors and the critical pressure head for collapsing under the pressure of floodwater
- by simplified modeling of pressure losses (discharge coefficients) in flows through typical openings.
- by feasible and realistic modeling of compartments with complex layout, such as cabin areas, for flooding simulation tools.
- by the use of flooding monitoring systems and time domain simulation for assessing the damage and flooding extent onboard the damaged ship
b) to establish a method for instantaneous classification of the severity of ship flooding casualty, with the following key objectives:
- Stochastic ship response modeling: establish requirements and uncertainty bounds for methods for prediction of the time it takes a ship to capsize or sink after damage.
- Rescue process modeling: establish requirements and uncertainty bounds for models of mustering, abandonment and rescue operations.
- Standard for decision making in crises: establish a loss function loss(N) and pN|i(N|decisioni) for the integrated standard. The loss function must reflect in a balanced manner the societal concerns pertinent to a “large” loss. The pN|i(N|decisioni) will reflect the above requirements on the methods to be used for generating basis information on stability, evacuation and rescue process as well as the associated uncertainty.
- Demonstration: develop implementation system and test effectiveness of the standard in rating different decisions for various casualty cases as well as test the approach in design environment.
