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.

Horizontal Mooring System 6 m OD Suction Pile Anchors (Suction piles are lowered to the seabed by an MPSV’s AHC crane. The MPSV’s ROV which helps pump the pile to design penetration in the same way that suction piles are installed worldwide. When all piles and mooring lines have been installed by the MPSV, the MPSV will pretension the mooring lines and leave the mooring lines with messenger cables to surface floats.)

Vertical Mooring System Gravity Anchors (If Vertical Mooring Loads Become Too High, The Gravity Anchors Lift Off The Seabed Limiting the Load On The Vertical Mooring Legs. The Guide Piles Return The Gravity Anchors To Their Original Location. Iron Ore Weight Requirement Is Reduced By Gravity Anchor Suction.) Gravity anchors at the bottom of each vertical mooring line prevent mooring line overload in the event mooring line clutch disengagement failure. May 9, 2016 26
