AW Energy Oy´s WaveRoller is the original concept to tame the surge in the nearshore areas. Although the major wave energy potential is clearly offshore in larger depths, apparently there still exist major drawbacks for the commercial-scale deployment of offshore devices, due to the necessity to rely on offshore maritime technologies, which on one hand are rather expensive and on the other hand are yet to prove their suitability for wave energy applications. For this reason, it shall be worth while to assess the value of on- and near-shore devices in particular in the present development phase: it is possible to use lower-cost modular technology and the devices are also much easier to maintain due to the proximity to the shoreline. WaveRoller is a unique, proven and patented product design for near-shore bottom wave (surge) energy conversion, and it was the first solution of its type (invented 1993 by Finnish professional diver). The detailed engineering, construction, deployment and monitoring of the simple and robust near-shore wave energy concept WaveRoller north of the Portuguese coastal town Peniche is an important step towards the large-scale reality of submerged near-shore wave energy utilisation. In addition to of the robust component and structural design, easy manufacturability and assembly, extensive technical and environmental monitoring activities will assure the appropriate assessment of the demonstaration plant .
