given paper is grabbed so much attention of 2nd year guys during brief explanation about "modern disruptive techniques".you will find out sweet and simple explanation of modern disruptive techniques to control pollution from ship at sea.

3. Our Goal…
•To make an Ultimate
Green Ship1.
•To Comply with IMO
Regulations2.
•Least Carbon
Footprint.3.

4. SOLAR SAIL TECHNOLOGY

5. NEED OF SOLAR SHIP:-

6. ENERGYSAILS

7. • A Rigid Sail device designed by Eco Marine Power
that allows ships to harness the power of the wind
and sun
• It is to reduce fuel costs plus lower noxious gas and
carbon emissions.
• It can be used even when a ship is at anchor or in port
and has been designed to withstand high winds or
even sun heat
• It will also help ships collect and store energy even
while docked.
• The sails — made of carbon fiber or steel — can also
be lowered during rough weather conditions.

8. FEATURES

9. Energy Sail - Key Features
 Flexible design. Can be upgraded and modified
after installation if required.
 Automatic positioning via computer control
system.
 Can be integrated with other systems and
equipment on-board ships via control system
architecture.
 Designed to be safe, robust & reliable. Multiple
layers of safety are incorporated into the design.
 Can be lowered and stored when not in use.
 Suitable for a wide range of ships and vessels.
 Pathway to low emission & low carbon shipping.

10. WASTE HEAT RECOVERY SYSTEM

11. MAIN ENGINE
EXHAUST
 PRIMARY SOURCE
OF WASTE HEAT
APPROXIMATELY
25% OF FUEL
ENERGY
HEAT FLOW AND
TEMPERATURE

12. UTILISATION
POSSIBLE TO PRODUCE
ELECTRICITY FROM A GAS
AN ELECTRICAL OUTPUT OF
UPTO 11% OF MAIN ENGINE
POWER
INCREASE IN TOTAL
EFFICIENCY TO ABOUT 55%
FOR A SLIGHT REDUCTION
IN MAIN ENGINE EFFICIENCY

13. Power turbine stand alone unit: PTG – Power Turbine Generator
Unit
Steam turbine stand alone unit: STG – Steam Turbine Generator
Unit
Combined turbines unit: ST–PT – Steam Turbine & Power
Turbine Generator Unit
TYPES
RECOMMENDATIONS…
 Main engine power > 25,000 kw – ST-PT
 Main Engine Power < 25,000 kw – PTG or STG
 Main engine power < 15,000 kw – PTG

14. Based on a HFO fuel saving of 3,555 tons per
year (with 3% sulphur content), the installation
of a WHRS on a large container ship will save
the environment for the following emission
amounts:
 CO2 emission saving per year: 11,260 tons
 NOx emission saving per year: 319 tons
 SOx emission saving per year: 214 tons
 Particulates saving per year: 29 tons

15. NO BALLAST SHIP

16. {
 A constant flow of local seawater through a network of
large pipes, called trunks.
The trunks runs from the bow to the stern, below the
waterline.
Ship continuously sweeps water through the ship and
out.
Ship is always filled with local sea water rather than
hauling seawater.
Reduces the harmful effects on the marine
environment.

17.  The pipes will function as longitudinal ballast tanks with
valves at fore and aft end of the ship which can be
controlled.
 Valves will be open to the sea during the ballast voyage to
ensure loss in buoyancy and closed during the loaded
departure and the sea water will be pumped out.
 Water will enter the pipes at the bow region of ship and will
flow out from stern region of ship.
 By this the local sea water will be present in the ship at any
point of time.

18. ADVANTAGES DISADVANTAGES
• Provides a significant
savings in power as much
as 7.3%.
• Difficulties in running at
rough seas.
• Construction costs are
much low.
• Difficult to maintain safe
draught while loading.
• No filtration system and
ballast tanks.

19. CONCLUSION
• The Disruptive technologies discussed would help in
making the Oceans cleaner & local species safe.
• Significant reduction in NOx and SOx, keeping in
mind the International Maritime Organization(IMO)
regulations.
