2.  GREENSHIP IS A TERM, USED FOR SHIPS
WHICH ARE MORE ENVIRONMENTAL
FRIENDLY, GREENER, LESS HARMFUL TO
SEA ANIMALS & ECOSYSTEM THAN
CONVENTIONAL SHIPS.

3.  SHIPPING IS ALREADY THE MOST
ENVIRONMENTALLY FRIENDLY MODE OF
TRANSPORT.
 EMISSIONS EMITTED FROM SHIPS ARE
SMALL (3%).
 IF THIS TECHNOLOGY COULD BE
INTEGRATED IN TODAY’S SHIPS THEN THEY
COULD BECOME 15-20% GREENER AND
CLEANER.

4.  REDUCTION OF GAS EMISSIONS.
 SHIP WASTE DISPOSAL.
 BILGE WATER TREATMENT.
 BLACK/GREY WASTE WATER TREATMENT.
 UNDERWATER COATINGS/PAINTS.
 BALLAST WATER TREATMENT.
 GREEN SHIP RECYCLING.

5.  PROBLEMS
› ENVIRONMENT POLLUTION.
› ACID RAINS.
› PARTICULATE MATTER IN AIR.

6.  ALTERNATIVE PROPULSION SYSTEMS:
› WIND ENERGY (KITES, SAILS ETC.)
› NUCLEAR FUEL.
› GAS PROPULSION.
› HYDROGEN/FUEL CELL.
› BIODIESEL.
› SOLAR ENERGY.
› WATER JET PROPULSION.

7.  FLUE GAS DESULFURIZATION
› SCRUBBERS.
› WET SULPHURIC ACID PROCESS.
 WASTE HEAT RECOVERY SYSTEM
› LESS LOAD ON ENGINE.
› LESS FUEL USED.
 ELECTRONICALLY CONTROLLED ENGINES.
› CAMSHAFTLESS ENGINES.
› ELECTRONIC V/V CONTROL.

8.  EMULSIFICATION COMBUSTION SYSTEM.

9.  USE OF HUMID AIR.

11.  PROBLEMS
› DISTURBS THE ECOSYSTEM.
› HARM TO SEA ANIMALS.
› UTILISE CONSIDERABLE SPACE ON SHIPS.

12.  WASTE COMPRESSORS.
› SQUEEZ & BREAK DOWN THE WASTE.
› LESS SPACE USED.
 USE OF RECYCLABLE PLASTICS.
 USE OF PLASMA TECHNOLOGY.
› REACH UPTO 6000 C & REDUCE COMPLEX
COMPOUNDS & PLASTICS INTO H2 &CO2.

13.  PROBLEMS
› OILY DISCHARGE IN SEA.
› HARM TO MARINE ANIMALS.

14.  USE OF MECHANICAL SEALS
› LESS CHANCES OF LEAKAGE.
 HIGH SPEED CENTRIFUGES
› USE OF MICROFILTERATION.
 USE OF CASCADE TANKS
› PURIFICATION USING SPONGE.

15.  PROBLEMS:
› GERMS TRANSFERRED TO SEA.
› HARMFUL TO SEA ANIMALS & ECOSYSTEM.

16.  MEMBRANE BIOREACTORS
› GENERATES BIOMASS AND PURIFIED WATER.
 USE OF VACUUM TOILETS
 USE OF INCINERATING TOILETS.

17.  PROBLEMS:
› MICROORGANISMS TRANSFERRED FROM ONE
ECOSYSTEM TO ANOTHER.
› DISTURBED ECOSYSTEM.

18.  TREATING BALLAST WATER BEFORE
BALLASTING.

19.  BALLAST FREE/NON BALLAST SHIPS:
› BALLAST TRUNKS ARE USED.
› VERY ECONOMIC.

20.  PROBLEMS:
› HARM TO MARINE ORGANISMS.
› SEA WATER POLLUTED.
 POSSIBLE SOLUTIONS:
› BIOCIDE FREE FOULING CONTROL PAINTS.
 FLAKED COPPER AND COPPER OXIDES CAN BE
USED AS ANTI FOULING PAINTS.
› MEDITOMEDINE ,A SUBSTANCE FOUND EFFECTIVE
AGAINST BARNACLES (THE MOST FOULING
ORGANISM)
› MICROCAPSULES (MADE OF POLYMER) ALSO
RELEALSE BIOCIDES WHICH REMOVES FOULING
ORGANISMS.

21.  TO ISOLATE PARTS OF SHIPS WHICH ARE
HARMFUL TO HUMAN AS WELL AS MARINE
LIVES.
 PROPER DISCARDING OF SHIP WASTE.
 REUSING PARTS OF SHIP WHICH ARE IN
PROPER CONDITION & REUSABLE.
 ASBESTOS FREE SHIPS & PROPER
RECYCLING OF OLD SHIPS WITH
ASBESTOS.

22. IT IS THE FIRST SELF SUFFICIENT, ZERO CARBON
SUPER YATCH.
IT GETS ENERGY FROM 3 SUSTAINABLE
SOURCRS OF ENERGY:
SUN
WIND
WAVE
SPEED OF YATCH: 18+KNOTS.
PRODUCES 50KW OF ELECTRICITY PER DAY.
DELIVERS 360MWH OF ELECTRICITY PER YEAR.
