Many features of the design have been patented internationally. Submersible mechanical and electrical machinery is becoming relatively commonplace and large submersible pumps of similar power levels to the generators needed for a tidal turbine are standard commercial products. This is familiar to most mariners; peak spring tide velocities of the order of 4 to 5 knots (2 to 2.5m/sec) are needed, with depths of water between 20 and 35m, for economic exploitation. This poses a significant structural or mooring problem. Modeling and Control of Marine Current Turbines and Energy Storage Although the relentless energy of marine currents has been obvious from the earliest days of seafaring, it is only now that the development of modern offshore engineering capabilities, coinciding with the need to find large new renewable energy resources, makes it technically and economically feasible to exploit it. The turbines have a patented feature by which they can take advantage of the reversal of flow every 6hours and generate on both flow and ebb of the tide. It is owned by the German automation company, Siemens. Marine Current Turbines - Headquarter Location, Corporate Office [4] It was the largest tidal turbine operating until SeaGen started. A decline in porpoise activity during installation that normalized after construction crews departed. Marine current turbine (MCT) blades are continuously exposed to seawater, making them extremely susceptible to marine biological attachment and causing MCT blade imbalance fault. [7], Two approaches are being followed, one for relatively shallow waters, up to 30 metres (98ft), and the other for deeper waters. The power train may be encased in an air filled nacelle using sealing arrangements for the drive shaft much like those used for ship propeller shafts, or alternatively it is possible to use dedicated sealed gearbox/generator units that can run immersed in water and therefore need no external casing. In order for wind turbine to generate the same power, wind turbine blades would need to be much larger than water turbine blades; the wind turbine would have to spins in much faster speed, and have to take over much more land than water turbine. Pelamis, Marine Current Turbines and other firms were named successful bidders for wave and tidal energy farm development leases in UK waters. A second phase of the R&D programme will follow a year later to develop and install a twin rotor commercial prototype of around 700 to 800kw.
