of fixed inflation air bag technology could be used to secure hydrostatic stability during evacuation and perhaps be of significant value to the underwriter given the potential to recover the vessel in a repairable state.
8. CONCLUSION
A computational method has been developed to assess the structural integrity and crash pulse signature of a very large high speed vessel. This method has also been able to evaluate
occupant crash kinematics. The crash
simulation shows that the crash bulk head works ensuring hull hydrostatic stability after impact. Oblique test need to be carried out to validate this over a range of conditions, as well as including water buoyancy. The use of a rigid wall as a worst case scenario crash target implies that if the CLF hit another vessel the crash pulse would be less. While this would be beneficial to occupant injury, the potential for the bow to penetrate the hull of another vessel and cause pollution needs further examination.
The crash simulation clearly identifies the issues of potential injury trauma and associated evacuation challenges. This requires a very different approach to the design
of CLF based on crash injury risk
simulation. A more detailed risk analysis of passenger location on the GA is required to inform passenger safety requirements as an integral part of the design process.
