| Research Abstract |
On an ocean development in the deep sea in the future, the introduction of the riser system using the flexible tube is examined as well as a conventional steel riser system.
It is predicted that external force by the motion of riser inside fluid becomes large as well as the external force such as a tide, waves and motions of the floating platform in this system. Therefore we produced 10m flexible riser model made by silicon and carried out the experiment in the water tank which showed the relationships among the flow quantity, the vibration and the shape and developed computational model for the analysis.
