New Trends in (Renewable) Power Generation
Modular Construction, assembled at the shoreline, floated and towed to location ready for anchor to the sea bed with all equipment installed and ready for operation. It is a coordinated system for extracting energies form; Sea Waves, Tidal, Solar Cold Water and Wind all Floating on a common tension leg platform (TLP).
The FloatNRG is a coordinated system for extracting renewable energies from; sea waves, ebb/tidal currents, solar, deep sea cold water, OETC and wind turbines. The system consists of an immersed (TLP) platform developed by submerged fixed floats whose top is below the trough line of sea waves, to support all energy extraction equipment, electric conversion and related switch and control equipment. The floating (TLP) develops a net uplift of 3-tons per square meter and a resisting moment of 80.599 ton-meters to resists storms with wind speeds up to 240Km per hour and is not affected by high waves. The system consists of modular fixed floats forming a (TLP) to support “floating construction units” (FCU)’s that provide closed space for energy extraction equipment and support for solar system. The (TLP) and (FCU) units are assembled at the shore line, floated and towed to location ready for operation.
a) Direct drive sea wave energy extraction,
b) Develops additional 0.932 KW or 2,992 KW hours per year, at each floating wind turbine support, and additional 4,462 KW or 14,577 KW hours per year at each 250m space between the wind turbine supports
c) Uses one unidirectional hydro-turbine to extract ebb/tidal and wave kinetic energies,
d) Provides compressed air storage of 3,772 cubic meters and 5,235 Cum. respectively at the Floating WT support and at the space between Floating WT Supports
e) Provides 16% additional power from each wind turbine support and additional 74% from the space between adjacent floating wind turbine supports.
Floating: wind turbine support, conventional Power Plants and substations, Marine laboratory Bridges and vehicular Causeways, islands, Docks and Wharfs for large tourist ocean liners and Residential Islands.
DESCRIPTION – (TLP)
The (TLP) consists of modular rectangular 3-D hollow shaped Fixed Floats (FXFL) whose tops are 50-centi meters below the trough line of the wave, made of high strength marine reinforced steel concrete to provide a net uplift of 6-tons per square meter.
The (FCU)’s “Floating Construction Units” are supported by the (TLP) to provide hermetic space for the equipment and to support the Solar System.
“Floating Construction Unit”
(FCU)’s are provided as two types; Active and Dummy.
(FCU-A) is an active unit providing support for wave, ebb/tidal and solar extraction equipment at a deck 5-meters above mean sea level (MSL) capable of handling waves up to 8-meters high including ebb/tidal level variations.
(FCU-D) is a dummy unit providing support for the (FCU-A) and for the solar system.
“Buoyant Floats” (BF) move up and down with wave undulations. The up and down movement is directly converted through a pulley system and sprag type clutch to rotary motion to drive electric generators at the (FCU-A) deck. Each (BF) develops a constant vertical uplift force of 2.65 tons. Three or more (BF)’s are installed in line with the incoming wave. Novelty……Direct Energy Extraction.
Wave Kinetic energy is extracted by the falling wave water directed through a hydro-turbine with vertical shrouds to increase its speed and installed below the trough line of the wave, to directly drive an electric generator at the (FCU-A) deck. Novelty Wave Kinetic Energy Extraction.
Ebb/Tidal Energy “kinetic energy” (KE) is extracted by channeling the water flow through horizontal shrouds to the same hydro-turbine, to develop unidirectional rotation and drive an electric generator at the deck of the (FCU). Novelty One Hydro-Turbine for Wave and Ebb/Tidal Kinetic Energy Extraction.
Solar Energy is extracted by (PV) cells installed at the roof of the (FCU) units.
Wind Energy is extracted using up to 6MW wind turbines installed on the floating (TLP).
Fixed Floats are the main elements of the (TLP) are installed below the wave trough line provide a net up lift of 3-tons per square meter sufficient to support the floating wind turbine, the (FCU)’s and respective equipment and necessary resisting moments to counter bending moments developed by storms.
Fixed Floats, (FCU)’s and equipment are assembled at the shoreline, floated and towed to location for mooring to the sea bed with all equipment ready for operation.
Deep Sea Cold Water available at 800m water depth is extracted for use as Air Conditioning medium (SWAC).
Floating Wind Turbine Support: Using FloatNRG system extracts 0.932 KW or 2,992 KW hours per year at each wind turbine support. Novelty…Power and Energy extraction at the floating wind turbine support.
Space between Floating Wind Turbine Support: Using FloatNRG system extracts 4,462 KW or 14,577,500 KW hours per year at each 250m space between the floating wind turbine supports.
Power and Energy extraction at the floating wind turbine supports.

COST per KW Hour
The given physical data, energy outputs, country, project location, project size and special requirements are sufficient for a main contractor/developer to estimate the total cost of the project and the resulting sale price of one (1) KWh.
A good and simple practical way for proving the viability and economy of the system, is for the Client/Consultants to request Bidders to submit in addition to their Bid, an Alternate Bid using the (FloatNRG) system.
