The following wave energy extraction system leads up to a “Coordinated Floating Energy Equipment” (COFEQ), extracting offshore energies from waves, tidal, solar, thermal and wind, supported by a “Floating Construction Unit” (FCU).
An (FCU) measuring 24.5 by 22.5 meters is completely assembled onshore, floated and towed to location with all equipment completely assembled ready for operation, can provide a peak output of 2.048 MW and 4,527,527 KW-Hours per year.
Adding fixed floats to the (FCU) and floating wind turbine floats, up scales the system for use as a floating wind turbine support, and adding floating floats would increase the compressed air storage capacity and area for solar system.
A 100MW wind farm using the (COFEQ) system provides the following:
The 899,772 to 509,686 cubic meters of compressed air reservoir are used as “Compressed Air Energy Storage” (CAES) system. In addition, the system provides a floating surface area of: 266,805 to 150,920 square meters for floating solar farms. These figures are for 3MW and for 7NW wind turbines respectively.
This would entice developers and owners to install a floating power plant with; security and freedom from political and local influential groups, provides access floating bridge and accommodation for operation and maintenance personnel.
Relocating the step-up gear and generator from the Nacelle of the wind turbine to the base of the floating support at the (FCU) deck removes the limitation of installing wind turbines in deep sea water, considerably reduces construction and operation and maintenance costs.
The cost of the project and positive long term cash flow based on electrical energy produced per year and the sale price of one (1) KW-Hour would determine the Return on Investment (ROI), which is estimated above fifteen (15%) percent. The project is practically self- financing.
The challenge for owners and developers is to request Developers and Contractors to provide an Alternate Bid based on the (COFEQ) system as herein described. This would provide a practical way for Bid Analysis and choice of a competitive system.
