| Research Abstract |
This study developed a method for predicting the motion of a very long pipe in water, which is used to convey fossil fuels resource from sea floor to the surface of the ocean. The motion of the pipe can occasionally cause collapse of the pipe. This method is useful to design the pipe considering the motion. And, this study examined the effect of attachment of small bumps on the reduction of the motion, and showed that the attachment can enhance the motion depending on position of the pipe where the bumps are attached.
