negative infinity. Thus, the maximum power absorption efficiency is calculated, and thevarious bodies may be compared in terms of efficiency. This work will hopefully haveimplications for wavemakers, wave energy conversion devices, and breakwater systems. Withrespect to WEC devices, this work mostly closely relates to terminators, which will bedefined in Chapter 2.3.20
CHAPTER 2. WAVE ENERGY CONVERSION DEVICE CLASSIFICATIONCurrent devices are listed and classified in Table 2.1. The classification systems are furtherdefined below, this is by no means an exhausted list of all classification systems. Theinformation in this chapter is a collection of the work done by Price (2009) and Carter(2005).2.1 LocationLocations to place WEC devices are:ShorelineNearshoreOffshore2.1.1 ShorelineShoreline devices are embedded into the coast, such as the Limpet, an OWC device in theU.K. (http://www.wavegen.co.uk/contact.htm). They are relatively cheap to maintain andinstall. It is also less expensive to transmit energy due to the relative proximity to the utilitynetwork (Drew, 2009). Shoreline devices are subject to a less powerful wave regime due toshoaling, friction, wave breaking, reflection, etc. This reduces the likelihood of the devicesdamaged by extreme wave conditions. However, there is less energy that could potentially beharvested. They are also site-specific, and thus cannot be mass produced. Additionally thereare aesthetic and noise impacts on nearby communities with shoreline devices (Drew, 2009).2.1.2 NearshoreNearshore devices are typically in relatively shallow water, approximately 20 meters deep.Again the devices are relatively easy to maintain and install compared to offshore devices.21
