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.

这项研究开发了一种预测水中很长管道运动的方法，该管道用于将化石燃料资源从海底输送到海洋表面。管道的运动有时会导致管道塌陷。该方法对于考虑运动的管道设计很有用。并且，这项研究检查了小凸块的附着对减少运动的影响，并表明该附着物可以根据凸块所附着的管道的位置来增强运动。
