Zhan, Canada COMMITTEE MANDATE: Concern for the dynamic structural response of ship and floating offshore structures as required for safety and serviceability assessments, including habitability. This should include steady state, transient and random responses. Attention shall be given to dynamic responses resulting from environmental, machinery and propeller excitation. Uncertainties associated with modelling should be highlighted. 2.4.3 CCS structural response 2.4.4 Current approaches for sloshing assessment 2.5 Air blast and underwater explosion 2.5.1 Air blast 2.5.2 Underwater explosion 2.6 Damping and countermeasures 2.7 Monitoring 2.7.1 Hull structural monitoring system 2.7.2 New sensors technology and application 2.7.3 New full scale monitoring campaigns and related studies 2.8 Uncertainties 2.9 Standards and acceptance criteria 2.9.1 Habitability 2.9.2 Underwater noise 2.9.3 Others 3.
