3.  The International Maritime Organization (IMO) has chosen “New technologies for greener
shipping” as the theme for World Maritime Day 2022.
 This theme reflects the need to support a green transition of the maritime sector into a
sustainable future, while leaving no one behind.
 The IMO actively supports a greener transition of the shipping sector into a sustainable future, and
showcases maritime innovation, research and development, and the demonstration and
deployment of new technologies.
Introduction

4. TYPES OF SHIPS
1. Container Ships
2. Bulk Carrier
3. Tanker Ships
4. Passenger Ships

5. Causes of Pollution
 Ships are responsible for a significant amount of pollution in the world’s oceans.
 They transport more than 10 billion metric tons of cargo each year, including clothing, electronics, and oil.
 The combustion of fossil fuels in ships’engines releases carbon dioxide, nitrogen oxides, sulfur oxides, and
particulate matter into the atmosphere,contributing to climate change and public health issues .
 Additionally, ships generate waste and garbage, including plastics, dunnage, packing material, cleaning
material, rags, paper products, food waste, remains of paints.
 solvents, and chemicals, which can contribute to marine pollution.

6. Methods to reduce Pollution
There are several green technologies that could be applied to existing vessels
 to reduce sulphur oxide emissions
 improve their carbon footprint
 These include fuel cells
 solar panels
 LNG as marine fuel,
 wind propulsion
 systems, SOx scrubber systems,
 waste heat systems,
 smart pumps,
 advanced propellers & rudders.

7. GREENSHIP TECHNOLOGY

8. DEFINITION
• GREENSHIP is a term used for ships that
contributes to improving the environmental
condition by using cleaner fuels, reducing
energy wastage, and minimizing carbon
output. It can also mean a brand name of
a company that provides natural and eco-
friendly products. Or it can mean a new
way to transport cargo in bulk faster than
conventional methods.

9. specification
• It is self sufficent ,zero carbon super yatch
• it gets energy form 3 sustainable
• avability of enegry
• 1.sun.
• 2.wind
• 3.wave
• speed of yatch :18+knots
• produces 50 kw of electricty per day
• delivers 360mwh of electricty per year

10. 2. LNG Fuel for Propulsion:
It is said that LNG fuel is the future of
the Shipping industry. LNG fuel helps in
reduction of air pollution from ships,
and a combination of LNG fuel with
diesel oil will lead to efficient engine
performance, resulting in fuel saving.

11. • 3. LNG Fuel for Auxiliary engine:
Auxiliary engines on ships are main
sources of power. Moreover they are
one of those machines that are
continuous running onboard vessels.
LNG fuel for such engines can
drastically reduce air pollution from
ships.

12. • Speed Nozzle: Speed Nozzles are
generally used in small supply vessels and
tugs to provide power to the ships. Along
with new design features of merchant
vessels, they can improve the propulsion
efficiency of the ship by saving power up
to approx 5 %.

13. • Exhaust Gas Recirculation:
In this system, NOx emissions
from the engine is reduced by recirculation of
exhaust gas from engine cylinder with
scavenge air which lowers the temperature
of the combustion chamber. Some part of the
exhaust air is re-circulated and added to
scavenge air of the engine which reduces the
oxygen content of the scavenge air along
with temperature of combustion cylinder.
With this method NOx reduction of up to 80%
can be achieved.

14. • Improved Pump and Cooling Water
System: An optimized cooling water
system of pipes, coolers and pumps can
result in decreased resistance to the flow.
This will lead to savings of up to 20% of
electric power of the ship and fuel
consumption up to 1.5 %.
