In addition, use of caissons has been maximized as this gives flexibility in construction sequence and programme and also minimizes requirements for rock which may be difficult to supply in the very large quantities required.

3m. Such heads are only available on approximately 55% of tides when the range is above about 7-5m. 5 m. 17. Inertia Requirements - The need for an inertia higher than that normally associated with bulb turbines arises from consideration of transient stability, that is the ability of the generators to maintain synchronism with the power system to which they are connected following a severe short-circuit fault in the interconnection. 18. Bulb turbine generators have lower inertia constants than vertical machines of equivalent rating due to the constraint on the diameter of the generator, lying as it does, within the water passageway.

5m by removing the top layer of very soft mud by dredging. 41. An alternative to placing embankment across the soft muds would be a landfall at the tip of Brean Down with the roads and cables taken under the Down in tunnels. This option could prove an attractive technical solution; however 41 DEVELOPMENTS IN TIDAL ENERGY it raises sensitive environmental issues as Brean Down is National Trust property and an area of outstanding natural beauty and this solution could presumably only be contemplated if it was shown to be preferable environmentally to disturbance of the soft mud area.
