<p>A method of installing a barrage across a body of water for generating electricity from tidal or current flow, the barrage being formed from a series of modules each of which comprises a base structure carrying a number of substantially vertical pipe structures in a spaced, side-by-side arrangement, and a deck structure that extending across the top of the pipe structures and is supported by at least two pipe structures, the method comprising: preparing a series of foundation terraces across the bed of the body of water substantially perpendicular to the direction of tidal or current flow, each foundation terrace providing a substantially flat base on which the base structure of one or more modules can be positioned; and positioning a series of modules on the terraces side by side such that the base section of each module rests on a terrace and the deck structure of each module is located at substantially the same height as that of its neighbouring modules. A module for use in the method comprises: a base structure defining a manifold; an inlet in the manifold housing an impeller that is connected to drive a generator; a number of substantially vertical pipe structures in a spaced, side-by-side arrangement mounted on the manifold so as to connect thereto, each pipe having a series of holes formed along its side facing its neighbouring pipe such that flow between adjacent pipes causes a venturi effect such that water is drawn from the manifold through the holes causing water to be drawn into the manifold through the inlet to drive the impeller; and a deck structure that extends across the top of the pipe structures and is supported by at least two pipe structures.</p> |
