| الملخص: | The major component of environmental loadings on offshore structures is the wave-induced loads. The time-domain analysis has been commonly preferred to assess offshore structures because it provides considerable benefits to the practicing engineer without losing accuracy. However, such assessments are high computational demands and time costs due to complex numerical procedures in completing the hydrodynamic loadings on the offshore structures. Moreover, a huge number of simulations is required to increase the accuracy, leading to a long processing time. Hence, a simplified analysis-based time domain is introduced by applying direct calculation procedures to overcome this issue. It refers to an efficient time simulation regression method called the ETS-RegSE model. The result of the Monte Carlo Time Simulation (MCTS) will be used to compare the performance of the ETS-RegSE model’s output. Provided with reasonable accuracy, the ETS-RegSE model offered a more efficient approach to optimal and costeffective structural analysis. |
