2.3.3 TerminatorsTerminators are perpendicular to the wave propagating direction. Their lengths are alsocomparable or longer than the wavelengths. Salter’s Duck depicted in Figure 2.3 is anexample of a terminator (Drew, 2009).Figure 2.3 Salter’s Duck (http://www.jeron.je/anglia/learn/sec/science/sn005/page02.htm)2.4 Operating PrinciplesOperating principles include (Drew, 2009):Oscillating Water ColumnsOscillating BodiesOvertopping Devices2.4.1 Oscillating Water ColumnAn oscillating water column (OWC) has two main components a partially submergedcapture chamber and a bidirectional turbine. The rise and fall of the water level increases anddecreases the air pressure. The change in air pressure rotates a turbine sitting above thecapture chamber. A typical shore-based OWC device is presented in Figure 2.4. The Limpetis an example of an OWC device.24
Figure 2.4 Oscillating Water Column (http://www.esru.strath.ac.uk)2.4.2 Oscillating BodiesOscillating bodies can further be categorized as floating, oscillating devices; oscillating wavesurge converters; or submerged pressure differential devices. Floating, oscillating devices caneither be fully or partially submerged. The kinetic energy of the waves moves the device.Multiple power take-off systems can be used for these devices. Examples of floating,oscillating devices include: Pelamis, PowerBuoy, and Searev (Falcão, 2010).An oscillating wave surge convertor also moves due to the kinetic energy of the wave. Theoscillating wave surge convertor is hinged to the sea bed, and is also a terminator since it ispositioned perpendicular to the incoming waves depicted in Figure 2.5. As the deviceoscillates it drives two hydraulic pistons, which are coupled with a hydraulic turbine. Anexample is the Aquamarine Power Oyster (Drew, 2009).Figure 2.5 Oscillating Wave Surge Converter (Callaway, 2007)25
