<p>A support system for a least one water drivable turbine (1) that when in operation is immersed in a column of flowing water, characterised in that the system includes a deck or raft (3) for supporting said at least one turbine when immersed, the deck or raft (3) having an inherent buoyancy which is such as to enable the deck or raft (3) to rise through the column of water upon reduction of the buoyancy, the arrangement being such that the associated turbine or turbines (1) can be raised above the surface of said column in order to access the turbine for maintenance purposes.</p> |
