Numerical and Experimental Analysis of Fire Resistance for Bulkhead and Deck Structures of Ships and Offshore Installations

Investigating the loss of integrity (E) in cabin walls and decks, as well role insulation capabilities, holds significant implications for preventing serious human, economic environmental damage caused by ignition cabins ships ocean platforms due to fires explosions. In this study, fire resistance A-60 class ship bulkheads decks was evaluated through two groups standard tests. first test, steel structure side bulkhead exposed fire, while second mineral wool L-shaped stiffeners deck fire. Numerical material models were established based on standards, temperature distribution structural deformation simulated using Abaqus. The results showed a good correlation with experimental data. maximum average increases unheated surface during test 158 °C 136 °C, respectively. corresponding values 176 138 °C. Upon conclusion experiment, displacement direction towards furnace from center wall 54 mm, deck, 28 mm. This research can provide guidance design fire-resistant compartment structures.
