摘要：The flotation ring, a vital component of the gravity-type fish cage in open ocean engineering, oscillates under the action of water waves. The wave forces on the element of the flotation ring can be represented by Morison formula. However, the computing results according to the common Morison formula can not be in good agreement with the experimental data. Therefore, the attempt to substitute the relative acceleration of water particle in the inertial forces is made. The fresh results improve the surge displacements in the negative direction to some extent. It is said that that the modification for Morison formula may provide another angle of view to describe the wave forces acting on the floating structures.
