Abstract: The present invention relates to a hydroelectric turbine recovery system, and in particular a system which significantly reduces the complexity of recovering a base mounted hydroelectric turbine from a deployment site on the seabed by providing a frame having an open mouth which can be advanced around the turbine before the frame is fully lowered into locking engagement with the base, thereby allowing the base, with the turbine thereon, to be recovered from the seabed.

Abstract: A security device includes an optically variable device (OVD) having diffraction-based micro-optics including at least one moiré magnified visual representation of a micro-object. A diffractive structure provides micro-objects with unique optical effects when the OVD is viewed through the micro-object structure from a predetermined relative observation point. In addition to magnifying the micro-objects, the diffractive structure can impart optical effects such as change in observed color, enhanced contrast, animation of the observed visual representation, and change in size or shape of the observed visual representation. The micro-objects and the diffractive structure can be disposed on the same or different portions of a substrate. A method of making OVDs, and an article employing such OVDs are also disclosed.

Abstract: There is described a method for controlling the output of a tidal hydroelectric turbine generator from a remote location, with the need for control circuitry to be housed local to the generator. The rotational speed of the turbine, and consequently the output power level of the generator, is controlled by varying the transmission line voltage of the submarine power cable connecting the off-shore turbine with an on-shore substation.

The method provides for a number of safety features, ensuring that all components are safe to handle during the installation operation, and also ensuring that the turbine will not start spinning during the installation operation.

Abstract: An optically variable device (“OVD”) with an integral image system that includes a focusing element and an array of micro-objects which, when viewed through the focusing element, changes in appearance depending on the relative location from which the OVD is observed. A security device including the OVD and methods for creating the OVD are also disclosed.

Abstract: The present invention provides a hydroelectric turbine support system, and in particular the combination of a base on which the turbine is supported on the seabed during use, and a vessel used to transport the turbine and base to a deployment site, and which are designed to allow, when the system is docked at a quayside or the like, the base to contact the seabed during periods of low tide and to support the vessel thereon during such periods, without damage to either the base or the vessel.

Abstract: The present invention provides a method of securing a hydroelectric turbine at a deployment site, for example on the seabed and in an area of significant tidal flow, which method enables the turbine to be located securely without risk of overturning or sliding out of position, but without requiring the use of piling or other complex fixing operations, by using the tidal flow to generate a downwardly acting force on one or more legs of a base on which the turbine is mounted.
