Mooring of multiple arrays of buoy-like WECs

For reducing the number of anchors required for mooring a plurality of WECs in a body of water, the WECs are arrayed in two patterns enabling the sharing of anchors among the WECs. One pattern comprises pluralities of WECs disposed in polygonal shaped cells with an anchor disposed beneath each cell connected to all the WECs in the cell. A second pattern comprises a tessellated pattern of contiguous cells with WECs at the interface between contiguous pairs of cells being common to both cells of the pairs.
