An engine support mount including an airframe structure having a first anchor surface and a length extending along an x-axis, with a second axis defined perpendicularly to the x-axis. A support member is fixed to the airframe structure and defines a first aperture and a second aperture. A mounting assembly includes an elongated arm and first and second primary attachment assemblies respectively attaching the arm to the support member at the first and second apertures, the arm having a second anchor surface. A moment arm reduction feature includes a lug fixed to one of the anchor surfaces and a corresponding fastener fixed to the other of the anchor surfaces. The first anchor surface is positioned on the airframe structure outside of the first and second apertures, and the second anchor surface is positioned on the arm outside of the first and second attachment assemblies.

A modular system of generating electrical power from mechanical energy of kinetic motion originating in current, waves, and tides, where the system resembles natural habitat and illustrates options for optimizing the transmission of current through the system. One or more branches elongate members containing current generators extend up from the bottom of a body of water. The elongate members move with water, in the manner of kelp, to actuate the current generators, and thus transform mechanical energy due to forces inherent in a body of water to electrical power.

The invention relates to a method for estimating a clearance (7) between a tower (2) and foundations (6) of a wind turbine (1), comprising the following steps: S1: acquiring N maximum accelerations of the tower (2) of the wind turbine (1); S2: associating a predefined interval of accelerations with each maximum acceleration; S3: determining the number of occurrences of each interval of accelerations over the N time intervals; S4: deducing therefrom a mode for the N time intervals; S5: repeating steps S1 to S4 multiple times so as to obtain multiple modes; S6: comparing the modes obtained in this manner and deducing therefrom a change in the clearance (7).

The invention provides a tool for moving a drivetrain component in a nacelle of a horizontal axis wind turbine, the nacelle comprising a nacelle structure, the component being connected, in operation of the wind turbine, to a rotor of the wind turbine, the tool comprising at least drive unit for moving the component in relation to the nacelle in a direction parallel to the rotational axis of the rotor, and a plurality of position adjustment devices adapted to be located between the nacelle structure and the component, and distributed so that rotational movement of the component can be provided by coordinated control of the position adjustment devices.

An underwater structure including a power generation apparatus including a main body; a mounting portion connected to the main body defining a mounting axis; a connection carrier, a connector mounted on the connection carrier; and an actuation mechanism in communication with the connection carrier. The structure further includes a support structure adapted for engagement with a bed of a body of water; a support housing; a support connection carrier attached to the support housing; and a support connector mounted on the support connection carrier. The mounting portion and the support housing are adapted to cooperate with one another for mounting of the power generation apparatus on the support structure. The connection carrier is releasably engageable with the support connection carrier, such that the connection carrier is moveable between an engaged position and a disengaged position.

The preset invention relates to wind turbines and, in particular inclining a wind turbine from the vertical position. A tower (102) of a wind turbine may be inclined from the vertical position in order to reduce the loads on the tower (102).

A hydro turbine with a runner unit allows adjusting the gap clearance downstream and between the runner end tip portion and the inner edge of the blades. This gap clearance may depend on the angular position of the runner blades.
