摘要： A foundation structure for locating an object mounted on the foundation structure on a sea bed or a river bed comprises an integral buoyancy device having variable buoyancy and a rigid control surface. The integral buoyancy device is movable relative to the foundation structure to vary the position of the rigid control surface and to control the position of the center of buoyancy relative to the position of the center of gravity. This stabilizes the foundation structure during submergence and surfacing. A method for controlling the deployment and retrieval of the foundation structure is also described.

The installation (100) comprises a machine (1), an alternator (2), a first converter (41), an electrical cable (3) which links the terminals of the alternator (2) to the first converter (41), a second converter (42), means of measurement (8, 41, 43), a control unit (5), the first converter (41) modulating the frequency and the current of the first electrical signal (S2). The method comprises a first prior step in which the value of a first quantity proportional to a reactive power is implemented in the control unit and a main step in which the control unit (5) determines the drive frequency and the drive current on the basis of an error equal to the difference between the first quantity and a second quantity which is both homogeneous to the first quantity, dependent on the reactive power of the first converter (41) and determined on the basis of a measured value of the current of the first electrical signal (S2).

摘要： An apparatus is provided for modifying the geometry of at least one part of a turbine, which can include a shell assembly that includes an outer shell that is shaped to modify the shape of a pre-existing element of a turbine. The outer shell of the shell assembly can be composed of a fiber-reinforced polymeric material and can at least partially define an inner cavity. The outer shell can be bonded to a structure to modify the geometrical shape of that structure. Thereafter, a polymer casting can be injected into the inner cavity via at least one injection port attached to the shell assembly. In some embodiments, one or more stiffeners and/or a core can be positioned within the inner cavity to help improve the bonding of the polymer casting to the shell and/or improve a structural property of the apparatus.
