Abstract
This report offers guidance for the matching of wave and tidal energy devices to marine energy sites and also for interaction between devices that make up an array. At the stage of writing this document arrays are in their infancy with most development focussing upon individual commercially viable devices tested in real sea conditions. There is however sufficient understanding and research to begin to offer generic guidance for the arrangement of devices within arrays. This information is collated herein to offer guidance for all aspects of the marine energy industry.
