Abstract: An underwater structure including a power generation apparatus including a main body; a mounting portion connected to the main body defining a mounting axis; a connection carrier, a connector mounted on the connection carrier; and an actuation mechanism in communication with the connection carrier. The structure further includes a support structure adapted for engagement with a bed of a body of water; a support housing; a support connection carrier attached to the support housing; and a support connector mounted on the support connection carrier. The mounting portion and the support housing are adapted to cooperate with one another for mounting of the power generation apparatus on the support structure. The connection carrier is releasably engageable with the support connection carrier, such that the connection carrier is moveable between an engaged position and a disengaged position.

Abstract: Power generating equipment comprises a support structure adapted to be disposed on the bed of a body of water, a buoyant power generating apparatus having a center of buoyancy, a winching device releasably engageable with the power generating apparatus, and operable to pay out and to retract a flexible winch tether. The flexible winch tether has first and second portions releasably connectable to one another, the first portion being connectable at one end thereof to the support structure and at a second end thereof to the second portion, and the second portion being attached at one end thereof to the winching device, and being connectable at a second end thereof to the first portion.

Abstract: A method of securing a load bearing structure to the bed of a sea, river or estuary. The method comprises placing the load bearing structure on the bed; forming a pile-receiving hole in the bed by means of drilling equipment which is connected to a surface vessel by flexible lines only so that the weight of the drilling equipment is supported by the bed, the drilling equipment being guided by the load bearing structure, and the load bearing structure resisting any non-vertical loads imparted to the drilling equipment; and withdrawing the drilling equipment and installing an attachment pile within the formed hole.

Abstract: Power generating equipment comprising a buoyant power generating apparatus and a support structure for the power generating apparatus, which support structure, in use, is disposed on the bed of a body of water, the power generating apparatus comprising a motor-driven winching device having a tether which is connectable at its free end to the support structure whereby retraction of the tether causes the power generating apparatus to be drawn downwardly through the body of water into engagement with the support structure, the power generating apparatus and the support structure being provided with means for aligning and latching the power generating apparatus with respect to the support structure upon engagement with the support structure.
