In this paper, the seismic response of a simple dynamometer model of a real outdoor jacket platform in Bohai Gulf in China was explored using experimental LabVIEW®2020 software and using ANSYS-2020 R1 software numerically, the experiments were carried out at the University of Baghdad on a shaking table with earthquake acceleration and on two different types Of the tremors: the first was uniform with a displacement (4.75 mm) and the second was EI Centro (PGA = 0.32 g). In order to simulate the actual operating conditions. The model was subjected to a series of random wave loads. A finite element model was created to determine the seismic response of the model. The results were obtained, and there was an excellent agreement between the numerical and experimental results
