Description

Using the results of numerous studies made on cylindrical columns and angular columns -- the major constituent members of semisubmersible structures -- a method of predicting the vortex making damping force on the overall structure is proposed, and the suitability of this prediction method is studied by comparing the predicted results with the experimental results. In addition, the results of this method were compared with the experimental methods in the treatment of the joints of members, the effects of mutual interference between the joints, and three-dimensional correction. thus a practical method has been proposed.
