Summary:A method for mounting a tidal turbine and an associated support structure in a river or sea bed includes mounting the tidal turbine to a support structure and mounting the support structure upon a base, the base being of such weight as to involve gravitational forces of such magnitude as to be sufficient to withstand forces acting in such manner as to tend to displace the turbine and the associated support structure. A periphery of an underside of the base is provided with expandable members, the expandable members being selectively expanded to position the base more nearly horizontal when in contact with a sea or river bed. The base is formed as a hollow shell enabling the base to be floated into position, and, when the base is in a desired position, sinking the base to the sea or river bed in a controlled manner.
