WWP -
Construction
 |
The WWP consists of a large Major Float
floating at the sea surface, connected by flexible lines and
a rod to a piston inside a submerged small
diameter reciprocating water pump. The WWP is anchored to
the sea bed and kept vertical by a submerged Pump Float. |
 |
Suction and Discharge Check Valves
regulate the flow of water into and out of the pump. |
 |
Pumped water is collected in a piping
network run at the sea bed and discharging into hydro-turbo
generator to provide power at required voltage and
frequency. |
 |
The WWP needs a minimum water depth of 14
meters. |
 |
Installing sets of 10-Pumps would
increase wave energy extraction.
|
 |
Discharge
pipes and cross dummy piping are in integral part of the
system mooring. |
WWP – Operation
 |
The Major Float moves up and down with
the incoming. For a 4 meter high wave the large volume
Major Float develops an uplift force up to 2,650 kilo-grams
that acts on the piston of a small diameter piston pump to
extract an average of 119 liters per cycle to 50 m head.
This is equivalent to extracting 58.14 KW from a 108 KW
incoming wave at an extraction efficiency of 53.83 %.
|
WWP - System
Construction
 |
A WWP field consists of multiples of
10-Pump sets to provide the required generator power output. |
 |
Installing ten sets of 10-Pumps each
(total 100 pumps) occupies 13.5 by 30 meters space. Water
pumped to 50 m and generator output are shown below. |
 |
System costs depend upon location, power
output and Client requirements. |
 |
The system output in KW-Hours per year is
the sum product of generator output in KW and the respective
wave height durations in hours per year. This information
would provide system yearly gross income. |
 |
The above data determines system
viability and profitability. |
