A generating sub-assembly 101, comprising a turbine 104 and an electrical generator 105, is supported by support mechanism 103 upon a support structure 102 which includes a mast portion 108 extending from a submerged buoyancy portion 106 to support the generating sub-assembly 101 above the waterline. The support structure 102 is buoyant and is free to roll when floating in water and the support mechanism 103 is hinged to allow the generating sub-assembly 101 to maintain an operational angle during the rolling of the support structure. The mast 108 may be J-shaped to maintain clearance between the turbine blades and the mast during backward rolling. The buoyancy portion 106 may include a ballast tank (405, fig.4) located below a buoyancy tank (404). Rotor ballast (201, fig.2) may be provided to keep the centre of gravity of the generating sub-assembly 101 below the hinge. The support structures may be arranged in an array (501, fig.5). |
