Technical seminar on

pelamis wave power

INTRODUCTION :

In fact that a large percentage of electricity is being

generated by using natural sources such as coal, gas etc.

By the end of this century coal will be almost extinct.

PELAMIS WAVE POWER is the world’s first

commercial scale machine to generate electricity in to

the grid from offshore wave energy.

Among the various options of Non conventional

sources of energy the WAVE ENERGY is considered as

the best option for the production of electricity.

why wave energy?

To protect the environment for future generations.

To reduce the carbon emissions of greenhouse gases and

consumption of limited resources.

wave energy is the one of the most environmentally nature

friendly form of electricity generation.

Wave energy could play a major part in the world’s efforts

to combat climate change.

It potentially displaces 1–2 billion tonnes of CO2 per

annum from conventional fossil fuel generating sources.

Pelamis Wave Power

The Pelamis Wave Energy Converter is a semi-

submerged, articulated structure composed of

cylindrical sections linked by hinged joints.

The Pelamis Wave Energy Converter also known as

GAINT SEA SNAKE .

CONSTRUCTIONAL DETAILS :

Each pelamis machine is of 120 mts long.

It has a diameter of 3.5 mts.

Each pelamis machine has three power conversion modules.

Each machine is rated to produce 750 KW.

Depending on the wave resource, machines will on

average produce 25-40% of the full rated output over the

course of a year.

Working process

• Waves resisted by

hydraulic rams.

• Hydraulic rams pump high pressure oil to hydraulic motors.

• Hydraulic motors drive electrical generators.

PRODUCTION OF PELAMIS :

Power module fabrication

Tube fabrication

Final assembly

The power conversion modules contains the power

capture systems.

The module consists of a fabricated and a painted

steel structure that is installed with motor generator

set, hydraulic Cylinders, and electrical control cabins.

POWER MODULE FABRICATION :

TUBE FABRICATION :

The main structural fabrication consists of steel tubes,

nose

and yoke sections.

The nose section is installed with transformer, switch

gear and

control system and is commissioned.

Each tube is fitted with cabling and connecting

transists

to ensure the correct displacement.

FINAL ASSEMBLY :

The completed module and tube segments are joined

together to complete the assembly of the machine.

These joints can be made both on the land and in the

water depending upon facilities used.

The fully assembled machine undergoes

commissioning

at on-site installation.

100% available technology.

No maintenance carried out at offshore site.

Minimum work on-site..

Lowest kWh costs in the market.

Each machine can provide sufficient power to

meet the annual electricity demand of

approximately

500 UK Homes.

ADVANTAGES :

Disadvantages

Disturbance or destruction of marine life (including

changes in the distribution and types of marine life near the

shore.

Once device is damaged we must replace with new device.

It is the world’s first commercial scale

machine to generate electricity in to the grid from

offshore waveenergy. It promises to be efficient

one.

So our request is to

“save energy, save the world,

save ourselves”.

CONCLUSION :

Any Queries…?
