It is very economically important for the planner of the submarine pipeline construction to estimate the required days for the construction. In generally speaking offshore constructions as the laying submarine pipeline are strongly affected by the waves. Therefore, it is important for estimating the workability of the submarine pipeline construction to predict the combined behaviors of the pipe laying barge, pipeline and stingers in waves. In this paper, the theoretical predicting method and the model test conducted verify such predicting method are shown. The predicting method, described in this paper, is the finite element method and directly solves the equation of motions in frequency domain. The predicted results were compared with that from experiments. Consequently, it is verified that the accuracy of the prediction method shown in this paper can be practicaly satisfied. As the first report, in this paper, the behaviors under forced oscillation test and test in waves are described.
