A clamping arrangement 30 clamps a mounting portion, eg flange 15, of an underwater power generating apparatus, eg turbine, to a mounting portion, eg flange 21, of a support structure 20. The clamp 30, eg one of several, has an open position, fig.6, allowing the power generating apparatus to be removed from the support structure; a closed position (fig.7) and a bearing position (fig.8) in which the power generating apparatus is rotatable relative to the support structure eg to reorient the turbine with tidal flow direction. Each clamp 30 comprises a clamp member 34 rotatable relative to a mounting portion 32 about a first axis in an actuation plane, the clamp 30 having a bearing surface 35 and an actuation point 37. An actuation ring 38 is rotatable by an actuator (44, figs.12-17) relative to the mounting portion 32 about a second axis (M, fig.3) perpendicular to the first axis. A spring 40 is attached between a point 43 on the actuation ring 38 and the actuation point 37 of each clamp member 34. |
