The purpose of this study is to obtain the base shear force and overturning moment of the jacket at the three wave heights of 20, 23 and 28 cm. In this regard, the model of the jacket structure is constructed at a height of 4.55 meters, 402 meters in length and 4 meters in depth of water, exposed to random waves of the sea and is subjected to the JONSWAP spectrum in the flume of Fars National Marine Laboratory (NIMALA). Based on the results obtained, in all examinations, deep water conditions prevail. Considering the effective wave, for the wave height decreases from 28 to 23 cm, 14.17%, 23 to 20 cm, 52.9%, 28 to 20 cm, 74.57%, reduction of the base shear; and for the decrease of wave height reduction from 28 to 23 cm, 33.79%, 23 to 20 cm, 17.06%, 28 to 20 cm, and 56.63%, overturning moment reduction were obvious.
