    • In an aspect the invention concerns a hydroelectric installation (10). The hydroelectric installation (10) comprises a turbine (12) for operative location within an aquatic environment. The turbine (120) comprises a first blade and a second blade formation (14, 16) disposed about a turbine hub (18). The turbine hub (18) longitudinally extends about a turbine hub axis (20). The hydroelectric installation (10) further comprises a turbine support (22) for operative support of the turbine hub (18) within the aquatic environment. The turbine hub (18) is secured to the turbine support (22) so as to be pivotal about the turbine hub axis (20) responsive to water flow across the first and second blade formations (14, 16). The first blade formation (14) is operatively adapted to be driven by water flow in a first direction and the second blade formation (16) is operatively adapted to be driven by water flow in a second opposite direction.

    • The present invention describes a floating yawing spar buoy current/tidal turbine. The spar includes a spreader above the rotor(s) with the spreader tips connected to fore and aft cable yokes that transition to opposing mooring lines connected to anchors on the seabed. The spreader comprises a yaw motor, which drives gears that engage with a ring gear fixed to the outer perimeter of the spar. Flow direction sensors activate the yaw motor for automatic yaw adjustments of the spar turbine. As tidal direction changes, the entire spar and turbine are yawed to maintain the rotor plane facing the tidal flow. The bottom end of the spar extends to approximately the bottom sweep of the rotor plane and contains a winched vertical mooring line, extending to the seabed and attached to a gravity or suction pile anchor. The turbine drive train can be accessed for servicing from the surface via hatches and ladders within the spar to enter the drive train and generating system vessel. The spar turbine is deployed by towing it in a horizontal position. At the operating site, the yokes are connected to the forward and aft mooring lines and the winch line is connected to the gravity anchor. The winch inside the keel draws the bottom end of the spar down and may be assisted by flooding the keel to reach a vertical position for the spar. The winch is then locked to retain required operating depth, or can actively control operating depth in areas of wide tide level range.
    • 本发明描述了一种浮动偏航翼梁浮标电流/潮汐涡轮机。 翼梁包括在转子上方的吊具,吊具末端连接到前后电缆轭,其过渡到连接到海床上的锚的相对的系泊绳。 吊具包括偏转马达,其驱动与固定在翼梁的外周边的齿圈啮合的齿轮。 流动方向传感器激活偏航马达,用于翼型涡轮机的自动偏航调整。 随着潮汐方向的变化,整个翼梁和涡轮机被偏转以保持转子平面面向潮汐流。 翼梁的底端延伸到转子平面的大致底部扫掠,并且包含绞合的垂直系泊绳,延伸到海床并附接到重力或抽吸桩锚。 涡轮传动系可以通过翼梁内的舱口和梯子从表面进行维修,以进入传动系和发电系统容器。 翼梁式涡轮机通过将其牵引在水平位置来部署。 在操作现场,轭架与前后系泊系连接,绞车线与重力锚连接。 龙骨内部的绞车将翼梁的底端向下拉,可以通过淹没龙骨来达到翼梁的垂直位置。 然后锁定绞盘以保持所需的操作深度,或者可以主动控制潮汐水平范围内的操作深度。
