Description of work

Task 2.1 Experiments with leaking and collapsing structures
(Responsible: CTO; STX, MEC, MW, AALTO)

The scope of the first part of the following Work Package includes experimental investigation of leaking and collapsing structures (partitions) with a use of new build mock-up stand. The work is divided into two stages:

Task 2.2 Numerical modeling and criteria for leaking and collapsing structures
(Responsible: MEC)

Task 2.3 Experimental studies on pressure losses
(Responsible: AALTO, Participants: STX, MW)

This task will be devoted to hydraulic experiments on specific configurations encountered in the flooding of a large passenger vessel. Special attention is put on the cross-flooding arrangement. The detailed parts of the ship to be tested will be selected. Tests with different modifications of a typical arrangement will be performed in order to derive conclusions on the effects of parameters, such as the number of girders and openings. In addition, doorways, manholes, down-flooding hatches, etc. will be tested. Large scale models will be used in order to minimize the possible scale effects. Measurements will be carried out in dynamic case, which enables the results to be used both in conceptual mathematical models and in the validation of the CFD-codes.

Task 2.4 Computational studies & RANSE CFD
(Responsible: CNRS, Participants: STX, CTO)

Task 2.5 Model tests for cabin areas
(Responsible: MARIN, Participants: STX, MW, NAPA)

In the EC funded SAFEDOR project flooding in RoPax ferries is investigated by means of model tests on cabin arrangements and simulations for ships. This work focuses on basic cabin arrangements with not too much level of detail. All available results from the previous studies will be used as a starting point for this new study in Task 2.5.

Task 2.6 Sensitivity of simulation model
(Responsible: AALTO, Participants: NAPA)

This Task will consist of simulations with a typical layout of ship. The input parameters of the simulations will be systematically varied in order to assess the sensitivity of the simulation results on these parameters. The sample ship designs produced in the WP1 will be used. Guidelines for the preferred accuracy of the input data along with simple error estimations will be provided.
