3.  The WEC is a new, highly efficient technology that harnesses
the immense, renewable energy contained in ocean waves. Its
unique ability to extract and convert energy from both the
rising and falling of waves represent a technological
breakthrough .
 A wave energy conversion apparatus comprises at least two
devices .The apparatus uses mooring system that maintain
the complete apparatus in a position

4.  In fact that a large percentage of electricity is being
generated by using natural sources such as coal, gas etc by
the end of the century coal will almost extinct
 Among the various options of renewable sources of energy
the WAVE ENERGY is considered as the best option for the
production of electricity
 PELAMIS WAVE POWER is the world’s first commercial scale
machine to generate electricity into the grid from offshore
wave energy

5.  The Pelamis wave energy converter (PWEC) is a semi-enclosed
, articulated structure composed of cylindrical sections linked
by hinged joints
 The Pelamis wave energy converter (PWEC) also know as
GAINT SEA SNAKE

6.  Main tube segment
 Power conversion module
 Main tube segment : The main tube is a semi submerged
articulated cylinder linked by hinged joints swings head on to
incident waves

7.  Power conversion module : The power conversion
module mainly consists of sway hinged joints, hydraulic rams,
high pressure accumulators, motor/generator set, main flod,
reservoir and heave hinged joint

10. ADVANTAGES AND DISADVANTAGES
Advantages
• Renewable
• Enivronment Friendly
• The energy is free of cost
• Not expensive to operate and maintain
• Can be produced a great deal of energy

11. Disadvantages
• Problem of Power transmission to shore
• Noise production at the site
• Navigation disruption are possible

12. CONCLUSION
Waves represent one of the most denesly powered natural fluxes which
can be directly used for renewable energy generation.
Furthermore , it can have a relatively large utilization time as the power flux
variations are attenuated when the waves are induced by winds which in turn
originates from solar power . In this present scenario of injudicious use of natural
resources wave energy will definitely play an important role in accounting for the
future energy needs
