The sloshing phenomenon is one challenging event in fluid-structure interaction especially for the liquid carrier such as a ship. Sloshing can endanger ships when there is energetic sloshing with volatile liquid inside the tank. One of the LNG carriers is membrane type which the tank is prismatic. The study aims to reproduce long-duration sloshing using a prismatic tank. The particle method so-called smoothed particle hydrodynamics is used to deal with long-duration sloshing. To accommodate of experiment condition a two-phase SPH is used. To accelerate SPH computation, a GPU solver is used in this study. The hydrostatic pressure from SPH is compared with an analytic solution and dynamics pressure is compared with experimental data to validate the results. The result shows SPH has good accuracy for hydrostatic pressure and dynamics pressure shows a similar trend to experiment with spurious pressure. Finally, free surface deformation has a tendency similar to experiment with void of air trapped in the water that can capture by SPH.
