Abstract:

A critical assessment of the Morison equation is provided. The Morison equation is used to calculate the loading on offshore structures due to ocean waves. The assessment covers both the original equation and the modifications currently in use by industrial designers. A review of the literature is provided. It is concluded that the Morison equation provides an adequate design tool provided careful consideration is given to the selection of the fluid kinematic representation and the empirical coefficients. Improvements in the accuracy of the operation can be achieved through research leading to 1 improved descriptions of the sea state, 2 better representations of the water particle velocities and accelerations in combined wave-current flows, 3 improved quantification of the drag and inertia coefficients, and 4 inclusion of the fluid-structural interaction.
