... of an underwater explosion (UNDEX) on a near-shore submarine pipeline. The response has been assessed for two pipeline configurations: lying on the seabed and suspended in a free span. Moreover, the influence of internal pressure was studied. A purpose-built finite-element model has been used to predict the local...

On this basis, the crashworthiness of the airbag anti-ship collision device with different sizes, thicknesses and initial internal pressures is analyzed by the finite element method. The results show that: with the increase of airbag radius, the peak acceleration of the ship does...
