Evopod
Evopod™ is a floating tidal stream turbine and therefore has low cost of intervention in the event of component failure. Component failure is inevitable in a multi-device farm installation and intervention must be simple, cheap and fast. Floating solutions overcome the disadvantages of bottom mounted devices. Floating solutions are more accessible for first line maintenance and, with the Evopod™ patented disconnectable mooring and power export solution, easily recoverable to sheltered water for servicing or repair activities. It is important that the floating platform supporting the turbines does not pick up motions from passing waves and that the turbine can be kept away from wave action in average sea conditions. Evopod™, unlike surface floating platforms, has small waterplane area struts and a deeply submerged nacelle ensure low motion characteristics. The streamline struts avoid wake interference with the turbine. Evopod™ is tethered to the seabed using a catenary spread mooring system with simple pin-pile or gravity anchors. Mono and twin turbine Evopod™ units for deployment at coastal sites exposed to harsh wave climates employ a swivel mooring connection that allows the free floating device to maintain optimum heading into the direction of flow. The multi-turbine support platform for more sheltered estuarine conditions is moored fore and aft and allows access and removal of individual turbines for maintenance. The mooring and ballasting arrangement can cope with large changes in tidal elevation and can provide a more environmentally acceptable solution than barrages for exploiting tidal estuaries.
