Abstract
A structure for a tidal flow energy generation system is fabricated from tubular framework having tubular modules with mounts for respective tidal flow turbine nacelles. The node modules include tubular limbs extending in transverse directions and elongate tubes and provided to interconnect with the tube limbs of the node modules. The structure can be pre-fabricated and transported to a location for deployment. The structure can be deployed by means of hovering the assembled structure to the seabed, for example by means of flooding the structure.

A structure that is deployed on a seabed for use in a tidal flow energy generation system that includes three tidal flow turbine nacelles, the structure comprising:
- three node modules each including a pair of limbs;
- and
- elongate members extending to interconnect with the limbs of the three node modules;
- wherein the pair of limbs of a respective node module extend at an acute angle relative to one another such that the three node modules are arranged in a triangular footprint with the three node modules positioned at respective vertices of the triangular footprint, and wherein the three node modules and the interconnecting members of the structure are configured to rest on or closely adjacent the seabed;
- wherein the three node modules each include a respective mounting structure and a shaft, wherein the shaft is received by the mounting structure and extends upward above the mounting structure, the shaft for supporting a corresponding one of the three tidal flow turbine nacelles above the level of the node modules and interconnecting members such that the three tidal flow turbine nacelles are operably disposed above the level of the node modules and interconnecting members, wherein the shaft extends along a first axial direction that intersects the corresponding tidal flow turbine nacelle;
- and
- wherein the three node modules each include a respective ground engaging element for transferring vertical loading to the seabed, the respective ground engaging element extending downward along a second axial direction to a tapered distal end for contacting the seabed.
