FIG. 5.17 Pelamis power matrix—power output in kW. Hatched regions are either conditions
prior to cut-in of the device (low energy) or survival (large or steep waves).

FIG. 5.18 (A) Theoretical and (B) technical wave resources at Bernera, Scotland, based on a sin-
gle 750 kW Pelamis device applied to a 10-year modelled time series. The wave input data were gen-
erated by a modified version of the wave model presented in [15], extended to a longer-time period.
technical wave resource requires access to a power matrix for the selected
technology (e.g. Fig. 5.17). A comparison between the theoretical resource and
the technical resource (based on a single Pelamis device) at Bernera in the
west of Scotland is shown in Fig. 5.18. Although both theoretical and technical
