Abrégé

A water current power generating system includes a support structure located on a bed of a body of water. A power generating apparatus, such as a water current turbine device, is mounted on the support structure, by way of a mounting portion. The system also includes a measurement unit operable to determine operating information relating to operation of the system, and a controller operable to determine loading on the system from such operating information, and to adjust a controlled parameter of the system such that loading on the system falls below a predetermined threshold value.

Abrégé

An underwater structure includes a power generation unit, which includes a main body, a mounting portion which extends from the main body and which defines a mounting axis, and a support structure adapted for engagement with a bed of a body of water, and support housing. The mounting portion defines a substantially continuous mounting surface which extends substantially completely around the mounting portion, and the support housing defines a substantially continuous support surface which extends substantially completely around the support housing. The mounting surface and support surface are arranged to abut one another substantially continuously when the power generation unit is mounted on the support structure. The mounting portion and the support housing are adapted to cooperate with one another for mounting of the power generation unit on the support structure in any polar orientation about the mounting axis.

Abrégé

An underwater structure includes a power generation apparatus and a supporting structure. A coupling is provided that allows attachment of the power generating device to the submerged support structure. The coupling incorporates the function of a yaw bearing allowing rotation of the power generating apparatus about a substantially vertical axis.
