In recent years, shock trials for surface ships have been conducted in many countries for qualification of ship integrity, systems and subsystems in response to shock. A ship trial identifies design and construction deficiencies that negatively impact ship and crew survivability. Such a trial also validates shock hardening and performance of shipboard equipments. However, live-fire ship shock trials and underwater explosion testing are both complex and expensive. As a possible alternative, numerical modelling and simulation may provide viable information on the details of dynamic characteristics of ships, including at the component and sub-component levels. Ship shock analyses were conducted using a finite-element-based coupled catamaran-type ship with a fluid model. This model is also applicable to underwater explosion (UNDEX) simulation for movements of a high-speed catamaran-type ship. Catamaran-type ship shock modelling and simulation were performed and the simulation results were compared with the empirical data. The high-speed catamaran-type ship shock analysis approach is presented and the important parameters are discussed.
