<p>An underwater structure 1 comprises a power generation unit such as a turbine 4, attached to a support structure 2 via a mounting portion 31. The mounting portion connects to the support by continuous support surfaces e.g. annular flanges 32, 51, which can engage in any relative rotational position, thereby reducing the need for accurate alignment during installation. An actuator 39 moves electrical connectors 57 in rotation to the correct alignment, and linearly to make up the connection. One of the connectors may be provided with positional float, e.g. through flexible mountings (figures 9-14) to allow for any misalignment due to manufacturing and assembly tolerances. The electrical connector 57 of the support part may be removable by locking actuators 53, 54 e.g. to allow for maintenance without requiring underwater cutting and welding.</p> |
