HYDRODYNAMIC COEFFICIENTS OF MOORING TOWER

Wave tank tests have been performed on an articulated tower to determine the hydrodynamic coefficients associated with the tower. The tower was a uniform diameter rigid cylinder and incorporated a localised sensing device. It was tested in three different phases: <1> fixed in regular waves, <2> mechanically oscillated in still water, and <3> free to move in regular waves. The Morison equation has been modified and extended to deal with each of these cases. The results are used to make comparisons of the drag force due to tower motion and water particle motion, to determine the functional relationship of the inertia force coefficient, added mass coefficient and drag coefficient over a wide range of Keulegan-Carpenter and Reynolds numbers and to determine the effect of tower orientation on these functional relationships.
