1. HI–FIN PROPELLER

6.
INTRODUCED BY HYUNDAI HEAVY
INDUSTRIES
 Energy saving device attached at the hub of the
propeller.
 Offsets the swirls generated by the propeller.
 The Fins counteracts the swirls to Improve
both thrust and efficiency.
 Hi-FIN can save up to 2.5 % of fuel in
comparison with the same type of vessels
without Hi-FIN.

ADVANTAGES
Improves Thrust and
Propeller Efficiency.
Fuel Savings up to 2.5%.
DISADVANTAGE
Generation of Noise.

2. SANDWICH PLATE SYSTEM

11.
SANDWITCH PLATE SYSTEM IN SHIP
BUILDING
 SPS is a structural composite material.
 Composed of steel and polyurethane elastomer.
 Replaces conventional metal plates and avoids usage of steel
which requires additional stiffening.
 In 1990, MV Golden Bell bulk carrier became the first vessel to
utilize this system.

12.
ADVANTAGES DISADVANTAGES
• Reduces welding and removes the
sources of stress concentration.
• Overlaying process is long.
• Less weight and low cost. • Requires specialized naval
architects for overlaying process.
• Vibrations are damped by the
elastomers.
• Sustains extreme loads and has
fire resistance properties.

• AIR BUBBLE LAYER
2
• AIR CAVITY METHOD
3
• WATER REPELLANT PAINT

16.
ADVANTAGES DISADVANTAGES
Reduces fuel consumption saving up
to 10%-13%.
Can not useful in rough weather.
Significantly decrease in Co2
emission up to 10-15%. Extra maintenance of double bottom
structure.
Does not affect hull integrity.
Reduces viscous drag.

4. NOSE JOB

18.
WAVE GENERATION

19.
OPTIMIZATION OF BULBOUS BOW.
Made using polymer or
thermosetting plastic.
since a ship’s bulb is not
exposed to high heat in
normal working
conditions and such
materials are easier to
work with than steel.
The bulb shape is
modified to a ‘reverse
pear-shaped’ section that
works well for working
drafts below design
drafts. .

20.
ADVANTAGES DISADVANTAGES
Reduced CO2 emissions by 23%. More prone to damage since
they are the first point of
contact with an obstacle.
Savings in bunker consumption
up to 20%.
May dig into the waves in rough
seas rather than lifting the hull.
Reduces drag and wave making
resistance.

21.
5. SPEED NOZZLE OR KORT NOZZLE

22.
ACCELERATING DUCT
 Propeller fitted with a
non-rotating nozzle is
known as a Ducted
Propeller.
 The inflow velocity is
increased by reducing the
pressure resulting in
increase in inflow velocity
& efficiency of the
propeller.
 Decelerating Ducts-inflow
velocity is reduced and
pressure is increased,
reducing the cavitation.

23.
ADVANTAGES DISADVANTAGES
• More efficient at low speeds.
• The additional shrouding
results in drag.
• Most beneficial for slow
moving vessel.
• They lose their advantage
over conventional propellers
at about ten knots.
• Increased propeller efficiency
with accelerating ducts.
• Unsuitable for propellers with
larger diameters.

24.
5. BUCKY PAPER SHIPS

25.
A thin sheet made up of carbon nanotubes (CNT).
Each CNT is 50,000 times thinner than human hair.
1/10th the weight of steel but potentially 500 times stronger in
strength and 2 times harder than diamond when its sheets are
compiled to form a composite.
The vessel built from this lighter material would require less fuel.
A research has already been initiated for the use of bucky paper
as a construction material of a future ship.

26.
ADVANTAGES DISADVANTAGE
• Reduces weight of the ship.
• Very High capital cost
approximately 200$ per gram
of CNT.
• Corrosion resistant ship shell.
• Less chances of fire since
flame retardant.

CIRUIT DESIGN AND INSTALLATION
CIRDUIT DESIGN INSTALLATION OF SOLAR SET

35.
ADVANTAGES OF SOLAR SAIL ONBOARD:-
• 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 Class NK.
• Sail Can be lowered and stored when not in use.
• Designed to be safe, robust & reliable. integrated with
ships via control system architecture.

36.
CONCLUSION:-
With this we conclude that our project “SUSTAINABLE
DEVELPOMENT OF SHIPS” provides a good knowledge about the
current technologies used on-board for emission of less harmful
gases and savings in fuel. The implementation of these
technologies makes the ships and the environment cleaner.
These methods also help to increase the efficiency of the ships.
Researchers are developing more methods to make the marine
environment and the ships clean.
