Estimation of Lift Force on a Rough Vertical Pile of Platform to Random Sea Waves

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, Milne forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two afferent approaches have been used to determine time series of lift forces. Along these lines, the determination of lift coefficients is discussed which have then been used to obtain transverse forces and compared with experimental data. The experimental data used in this study were collected at Delft Hydraulics Laboratory on a full-scale rough vertical cylinder.
