N2 - Tidal energy generators are usually deployed in high velocity near-shore channels, and consequently the foundations may have to be placed on exposed rock seabeds, as surface sediments may have been eroded. In this paper, key engineering characteristics of some rock types found at locations with high energy potential around Scotland are presented, along with practical issues for foundation deployment that have been identified during field visits. Geomorphological features found at beach locations and wave cut platforms, along with the effect of weathering on rock strength, are presented and discussed. Laboratory characterisation and results from rock-steel interface testing utilizing the direct shear box apparatus suggest that relative surface roughness has the potential to significantly affect foundation-rock horizontal capacity.
