Dynamic Performance and Crashworthiness Assessment of Honeycomb Reinforced Tubular Pipe in the Jacket Platform under Ship Collision

The collision between the pipe legs of jacket platforms and bypassing ships is great concern for safety assessment platforms. Honeycomb structures have been widely used owing to their unique deformation mechanical properties under dynamic impact loads. In this paper, two typical honeycomb structures, namely hexagonal arrow honeycomb, were constructed protection inclined in platforms, present study aimed assess dynamical performance crushing resistance designed reinforced structure ship by using numerical simulation software ANSYS/LS-DYNA. leg was investigated considering various influential parameters, including velocity direction. crashworthiness types evaluated compared different criteria, maximum depth (?max), specific energy absorption (SEA) proposed index offset sliding (OS). results demonstrated that both can reduce damage caused collision, while provide better anti-collision capacity, which well protect from collision.
