Abstract

The hydrodynamic forces induced by combined irregular waves and currents acting on a small-diameter pipeline are investigated based on some physical tests. The results suggest that the Morison equation leads to poor predictions of the timevariant forces when the pipeline is mounted on the bottom. For the on-bottom cases, the method suggested by Jacobsen et al. (1988) is demonstrated to work better than the traditional Morison equation. However, the Morison equation performs reasonably well on describing the temporal forces when the pipeline is far away from the seabed.
