Key Messages

S Hybrid Ship sailing in ballast

conditions does not requireballast water, except for purified

clean ballast from middle of

ocean (subject to weather).

S Next generation ship design.

S Using little ballast means:

S no need for ballast watertreatment;

S no contaminated ballast waterfrom a foreign ecosystem.

S More fish eggs, more organic fishessurvive

S Gulf of Kutch;

S Arabian Gulf;

S Tokyo Bay.

Hybrid Propulsion System

VLCC draft with full load

21 meters

this draft is typical for delivering crude oil toconsumers via South Africa and Suez canal

need for ballastwater leads to tankerreturn trips

VLCC draft with water ballast load11,6 meters

draft of VLCC with hybridpropulsion system in ballastconditions

4 meters (+4 m thrusters)

providing an opportunity to return VLCC-type vessels to origin via a variety of routes

Two separate propulsion

systems in hybrid ship

Main Engine with

Main Propeller

S Diesel engine;

S Main propeller with rudder;

S Full load of ballast water isrequired when sailing withoutcargo.

Electric Motor with

Retractable Propeller

S Electric motor;

S Retractable 360-degree rotatingpropeller under the ships bottom;

S Minimum ballast water is requiredwhen sailing without cargo;

S Clean fresh water can be used asminimum ballast.

What is the difference?

Hybrid min-Ballast Ship

S Low-output efficient electric-

driven propeller;

S The easiest and most logical way

to protect ocean species;

S Reduced fuel consumption and

environmental pollution when

sailing without cargo.

Conventional Ship

S Using the main engine in fullballast condition;

S Ballast Water Exchange damagesthe environment, with specificharm done to fish and plankton;

S Ships heavily pollute theenvironment, even when theycarry no cargo.



9/15

What are the merits?

S Low draft means minimum water resistance with lower fuel oil

consumption;

S Main propeller is not in operation when ballasting, so this timecan be used for maintenance works;

S Main propeller output is fit for optimum most economical design,

i.e. setting mode for 85pct load basis;

S Less barnacles build-up on side shells, as they will dry up duringminimum ballast voyages.

Major VLCC, Capsize Ships

Are 50% Ballast Sailing

S West to East traffic with cargo;

S East to West traffic with ballast;

S More storage with slow steaming movement is dream

business.

News for the Shipping Market

Building New Ships

S New orders will be reduced;

S Trendsetters will have huge

bargaining power;

S Ballast water treatment may

become hot issue again.

Existing Players

S Old ships suddenly gain value,

and provide licensing and royalty

opportunity for alliances;

S Extra competitive edge.



14/15

Impact on US Environment

Ballast Water ExchangeS Controversial rules

S Nature destroyed?

S Less fish and ocean species?

Little Ballast SailingS Friendly for the

Environment

S Preserving the Nature

S More organic fish
