SLIDE 3 Super Watt Wave Catcher Barge Full Scale Dimensions
This presentation documents the basis of costs for the Super Watt Wave Catcher Barge for an offshore Oregon or Washington type installation site in about 100 meters of water. The costs include recent design updates, a design for most components, vertical and horizontal mooring system cost quotes, 20% contingency, etc. and are based on the economies of scale and the efficiency of a large power farm
- installation. The resulting CAPEX and OPEX are significantly less than land based wind power. With an expected capacity factor of about 60%, Super Watt Wave Catcher Barges should be the lowest LCOE
power plant option near significant wave locations. Super Watt Wave Catcher Barges can be sized for larger swell wave locations and produce even better economics. Super Watt Wave Catcher Barges can be sized for smaller swell wave locations and still produce better economics than land based wind power.
