The document discusses the development of solar-powered ships, specifically highlighting the m/v Auriga Leader, which is the world's first cargo ship partially powered by solar energy, generating about 10% of its operating power through over 300 solar panels. The initiative aims to reduce reliance on fossil fuels while addressing environmental concerns, with further projects being developed, such as the Indian Navy's solar-powered ship Sarvekshak and the solar ferry Aditya. The advantages of solar power on ships include a cleaner energy source, lower operational costs, and the potential for retrofitting existing vessels.

1. SOLAR POWERED SHIP
AN INITIATIVE…..

2. SOLAR POWER:- Solar energy is radiant light and heat from the Sun that is harnessed using a range of
ever-evolving technologies such as photovoltaic cells and battery arrangement.
It is an important source of renewable energy and its technologies are broadly characterized as
either passive solar or active solar. Active solar depending on how they capture and distribute solar
energy or convert it into electricity. Active solar techniques include the use of photovoltaic
systems, concentrated solar power and solar water heating to harness the energy.

3. NEED OF SOLAR SHIP:-

4. INSTALLATION OF SOLAR PANEL ONBOARD FOR COST EFFICIENCY:
As we know, these days everything from
rooftop to cellphones comes equipped
with solar power.
Now huge cargo ships are the latest
entities to join the solar power fray THE
M/V AURIGA LEADER organized by
PORT OF LONG BEACH,TOKYO
constructed by NYK SHIPPING LINES
R&D DEPARTMENT
That will power the ship’s main
electrical grid making First Ocean going
ship propelled by sun’s ray. The project
aims to reduce dependency on diesel
and heavy fuel oil. Solar power has
been used from decades to generate
power for auxiliary machineries, deck
lighting and electronic equipment

5. THE M/V AURIGA LEADER (NYK SHIPPING LINES R&D DEPARTMENT)

6. AURIGA LEADER’S SPECIFICATION:
• Auriga Leader, a RoRo Ship, is
the world’s first partially
propelled cargo carrier ship
fitted with over 300 solar arrays
that generate around 10 percent
of its required operating power.
• The solar powered ship
measures almost 200 meters
lengthwise with a width of
slightly over 32 meters
• With a depth of over 34 meters,
the Auriga Leader has a DWT of
almost 19,000 tonnes and a GRT
of around 60,000 tonnes.
• . The vessel’s owners, the
Nippon Yusen and the Nippon
Oil companies have invested
almost US $ 2 million in order to
ensure the successful working of
the Auriga Leader RoRo Ship.

7. POWER PRODUCED BY AURIGA LEADER:
• M/V AURIGA LEADER consist
300 panels is helping to power
the ship’s thruster, hydraulics
and steering gears that provides
sufficient energy to run
machineries. It produces
400kwatt energy to run auxiliary
and electronic equipment like.
• POWER CONSUME BY:-
1. ENGINE ROOM EQIPMENT
2. BRIDGE EQIPMENT
3. GALLEY & ACCOMODATION

• Etc.

9. CIRUIT DESIGN AND INSTALLATION
CIRDUIT DESIGN INSTALLATION OF SOLAR SET

10. COST & MAINTENANCE OF PHOTOVOLTIC CELLS
• COSTY OF SOLAR PANELS:-
Currently solar cells for a very wide range of prices, with most marine
grade panels priced from around £200 to well over £500 per 100 watts.
It depends upon the quality of solar plates is been order by respected
marine company.
• MAINTENACE OF SOALR PANELS ON BOARD:-
Solar panels generally require very little maintenance since there are
no moving parts. A few times a year, the panels should be inspected for
any dirt or debris that may collect on them.

11. Advantages and Benefits of Solar Power on Ships:-
• Clean source of power particularly useful when a ship is in port or near
populated areas.
• Can be used as source of power for emergency lighting which will outlast
traditional back-up systems.
• The use of special lightweight & flexible solar panels allows for more solar
to be installed on ships e.g. on awnings, angled surfaces, areas where
access is needed.
• The solution meets Classification Society requirements and the basic
configuration has received acceptance from ClassNK.
• When combined with efficient marine LED lights the effective output of
the system can be increased by a factor of x5 or more.
• Suitable for retrofitting to existing ships or for inclusion into new
shipbuilding projects.

12. FUTURE ASPECTS AND INITIATIVES:-
Indian Naval Ship Sarvekshak has
undertaken an innovative project for
provision of electricity onboard using
solar energy. The ship has installed 18
light weight flexible panels of 300 W
each, which are 100% marine
compatible. This power source can be
used at sea as well as in harbor. This
green initiative of the Indian Navy saves
approximately 89.1 kg of carbon
emission per day when compared with a
diesel generator. The estimated savings
in a service life of 15 years is expected to
be about Rupees One Crore.

13. ANOTHER EFFORT SHOWEN BY “CUSET” STUDENTS AND ITS
R&D DEPARTMENT :
1. They constructed ferry named “ADITYA”
powered by 50 solar panels.which
produces 40KW power & attain speed
upto 7 knot.
2. The operational cost of the boat, Aditya,
is Rs 163 per day against a diesel boat’s
Rs 7,000 says Shaji Nair, director of
Kerala’s water transport department.
3. Two electric motors and a lithium battery
is used in the boat. The boat is 20 meter
long and seven meter wide. It can travel
at a speed of 14km per hour. The
construction of the Rs 1.50-crore boat
took nearly two years. The boat has a
seating capacity of 75.

14. CONCLUISON:-
• Since it has been decades that human race is depend on oil
based fuels (nonrenewable source) for transportation because of
its availability, but now not only resources are reducing, pollution
is also increases due to over consumption.
• It is a time when human has to use its intellectual idea to
implement technology that can use renewable sources like
sunray, wind power and thermal energy to run the system to
maintain cost efficiency and environment stability.
