Full scale study of the wash of high speed craft

摘要

The Barcelona-Palma route is divided into various segments to perform the wave wash study. As regions near to Barcelona and Palma have restricted water depths, the wave wash effects are expected to be more significant compared to regions away from coastal areas. The operating condition of High Speed Craft (HSC) in many of the segments in the region is found to have shallow water effect. The wave washes created by the HSC is studied for the cases when inbound and outbound routes are same. The variations in vessel speed in different segments of the route in both directions have been considered separately for analysis. The direction of propagation of the waves generated by the craft in the outbound trip is generally away from the shore region in Barcelona and Palma. Hence impact on the shore region is much less compared to the impact due to waves generated by the vessel in the inbound trip, where the vessel created waves are directed towards the shore. Finally guidelines for HSC route optimisation is provided.
