The greatest vibration occurs in the engine room, but all other parts of the ship also experience vibrations because it is propagating. Even though there are methods to reduce these vibrations such as engine beds, they can only reduce the damaging effects and cannot completely eliminate the vibrations themselves. The method used in this research is to compare the measurement of good vibrations in the conditions before the addition of construction and after the addition of construction for later comparison with numerical calculation data. The purpose of this study is to obtain the maximum vibration value in the conditions after the addition of the gorger construction before the addition of the side deck girder construction as a means of evaluating the side deck girder construction planning in the ship engine room ship 2000 DWT. The result consideration of adding construction becomes one or the alternative in providing reinforcement so that it can reduce the vibration that occurs. From analyze results after addition of a sized T profile FB 180 x 8 mm FP 75 x 10 mm, which ranges from 28 - 29 m/s2 for the x-axis vibration value, while for vibrations on the y-axis the maximum is 10-11 m/s2, and on the maximum z-axis. at 20-21 m/s2, this analyze vibration is based on the time between 0 - 15 seconds or per 15 second interval, able to reduce percentage of vibration in the ship engine room area is 34.91%.
