UNITED NATIONS FRAMEWORK CONVENTION ON CLIMATE CHANGE (UNFCCC) - IN ITS KYOTO PROTOCOL DECIDED TO:

The CO2 reduction level (grams of CO2 per tonne mile) for the first phase is set to 10% and will be tightened every five years to keep pace with technological developments of new efficiency and reduction measures.

The reduction rate is calculated from a reference line representing the average efficiency for ships built between 2000 and 2010.

Reduction rates have been established until the period 2025 to 2030 when a 30% reduction is mandated for applicable ship types.

Ship Energy Efficiency Management Plan (SEEMP) and Energy Efficiency Operational Indicator (EEOI)

The Ship Energy Efficiency Management Plan (SEEMP) is an operational measure that establishes a mechanism to improve the energy efficiency of a ship in a cost-effective manner. The SEEMP also provides an approach for shipping companies to manage ship and fleet efficiency performance over time using, for example, the Energy Efficiency Operational Indicator (EEOI) as a monitoring tool.

04/21/2304/21/23 2525


Ship Energy Efficiency Management Plan (SEEMP) and Energy Efficiency Operational Indicator (EEOI)

The guidance on the development of the SEEMP for new and existing ships are given in (MEPC.1/Circ.684).

The SEEMP urges the ship owner and operator at each stage of the plan to consider new technologies and practices when seeking to optimise the performance of a ship.

04/21/2304/21/23 2626

The EEOI enables operators to measure the fuel efficiency of a ship in operation and to gauge the effect of any changes in operation.

Example:

(1)Improved voyage planning (or)

(2)more frequent propeller cleaning, (or)

(3)introduction of technical measures such as

waste heat recovery systems (or)

(4)a new propeller.

SUGGESTIVE MEASURES FOR -REDUCTION OF CARBON SUGGESTIVE MEASURES FOR -REDUCTION OF CARBON FOOTPRINT FOOTPRINT

AND GHG EMISSIONS FROM SHIPSAND GHG EMISSIONS FROM SHIPS

There is a method of marine adaptation and migration of a commercial land based carbon foot print reduction system (used in Power plants and other land based facilities), integrated to the platform of a proven marine fuel saving system.

To leverage proven existing technologies that have been successfully applied to land-based emission sources and integrate it into a proven marine energy conservation system to develop a system that will measure and minimize Carbon Foot Print (CFP) and further increase fuel efficiency.

04/21/2304/21/23 3434

The proposed system will, in real time, measure and record the shipboard energy consumption and CFP to allow continuous CFP Benchmarking.

Management, Control and feed information and instructions to allow additional implementation of continuous energy consumption and CFP improvements.

The proposed system will allow the ship’s Engineers and the ship’s operations managers to make operational and other changes to optimize fuel consumption and minimize the CFP.


04/21/2304/21/23 3535

The predominant constituent of GHG is CO2.

Method-I: Carbon emissions can be determined by either direct monitoring of CO2 emissions using: Continuous Emission Monitoring System (CEMS) or calculation from proper emission factors, fuel consumption, and relevant operating parameters.

Method-II:Parametric Emission Monitoring System (PEMS). PEMS relies on operating parameters that are already monitored for operating purposes (e.g., fuel consumption, combustion parameters, etc) and sometime apply advanced algorithms such as neural network to predict emissions.


04/21/2304/21/23 3636

The protocol embedded also addresses the carbon associated with stored energy that is brought on board and consumed. This may include batteries, supplied shore power at port, etc., which reduce the overall carbon footprint as compared to shipboard power.

Using the system the CFP can be determined at individual vessel level or fleet level.

04/21/2304/21/23 3838


This system provides a fundamental basis and foundation for the phased effort to provide each ship with a self managed energy conservation and carbon footprint reduction system.


04/21/2304/21/23 3939


• shipboard systems have many more variables and modes of operation.

• A ship is more complex and has many more, smaller systems than say a power generation plant on shore.

• This includes items such as the propulsion plant, power generation system, boilers and on board incinerators.

04/21/2304/21/23 4040


The ship’s Master and Chief Engineer are able to change many variables like;

ship speed, course, loads on the electrical bus, number of generators on

line, Engine RPMs, ship’s ballast condition, hull trim, etc)

and the ship operations manager can change many others (like route, sailings, loading, hull and equipment maintenance status, etc).

04/21/2304/21/23 4141


The system will help the ship owner to document the reductions and use the reductions as emissions credits or for positive public relations efforts.

THUS EEDI (Energy Efficiency Design Index) & EEOI (Energy Efficiency Operative Index) can be achieved and monitored for further reductions as stipulated in MARPOL Annex-VI.

The computer based route optimization and weather data display package provides masters with the tools upon which to conduct efficient voyage planning with resultant improved safety and voyage performance.

• Optimum route - either for minimum time or minimum fuel.

• Alternatively the master can set certain weather thresholds which should be avoided along the optimized route as well as define no go areas that are blocked for the optimization.

• The Master can then compare this Optimum track with any number of reasonable alternatives. while reducing fuel consumption.04/21/2304/21/23 4343

As such the features achieved are:

(i)Standard Optimum Ship Routing Service(ii)Forecasting storm strength and effects(iii)Resonance AlertsFleet managers can see in an instant, all in one place, information that could have otherwise taken hours to gather from many sources.Vessels appear on the globe as color-coded icons that can be customized to provide fleet managerswith alerts regarding ship performance, fuel consumption/carbon emissions, weather conditions, ETAs or other factors.

04/21/2304/21/23 4444


Optimizing Operating Parameters: As the emissions are directly related to the consumption of fuel onboard, the various options considered will be evaluated according to influence on fuel consumption.

The ultimate goal is to arrive at the optimum energy used per cargo ton mile for each ship. Even as this baseline is iteratively determined for each existing ship’s current configuration, further efficiency improvements, reduced energy consumption and reduced GHG emissions can be incorporated by implementation of maintenance techniques and configuration changes discussed later.

04/21/2304/21/23 4545


OPTIMIZING OPERATIONAL PARAMETERS TO CONTROL OPTIMIZING OPERATIONAL PARAMETERS TO CONTROL THE FUEL CONSUMPTIONTHE FUEL CONSUMPTION

1.Choice of speed:

For any ship in a given condition, the fuel oil consumption, and thus the green house gas (GHG) emission, will mostly be a function of energy consumed to attain the ship’s speed. Most ship engines, running at reduced speed or slow steaming could have problems. Such problems may be vibrations (critical RPM of the engine shaft) and accelerated soot accumulation due to incomplete combustion in the exhausted gas channel. Thus a favorable balance of speed and GHG emission will need to be reached.

04/21/2304/21/23 4646

2. Speed or Power Variation:

Constant speed or power variations during a voyage, compared to steady running, increase infuel consumption.

3. Weather Routing:

Varying weather, current and depth conditions during a voyage affect the ship’s speed, which can result in an energy savings potential of 3-5%.

04/21/2304/21/23 4747


4. Optimal Trim:

Optimal trim to attain maximum speed at a given mean draft and engine power can result in an energy saving potential between 0.1-1.0%.

5. Optimal Propeller Pitch:

Optimal propeller pitch on CP propellers canprovide an energy saving potential between 0.1-2

%.

04/21/2304/21/23 4848


6. Minimum Ballast:

Decreasing ballast and extra bunker to a minimum could result in an energy saving potential between 0.1-1 %.

7. Improved Fleet Planning:

Better utilization of fleet capacity can often be achieved by improved fleet planning. An increased fleet utilization will result in reduction in energy consumption and hence reduction in the GHG emissions.

04/21/2304/21/23 4949


8. Optimal Rudder: Steady rudder / Minimum Rudder angle variations to keep total fuel consumption at a minimum with autopilot adjustments could provide an energy saving potential between

0.1- 0.3 %.

9. Vessel Capacity Utilization: This will directly influence total GHG emissions.

04/21/2304/21/23 5050


10. Anchoring and Mooring:

Time saved in port or in efficient mooring, berthingand anchoring may be used to reduce ship speed

at sea and thus save fuel. Reductions in GHG emissions up to 1-2 % may be achieved.

04/21/2304/21/23 5151


11. Increasing Hull Efficiency: The impact of hull maintenance on the fuel efficiency and GHG emissions is through the effect of hull roughness on ships resistance. For the service life of a vessel, an increased hull roughness implies increased viscous resistance which results in an increased power demand to maintain speed.

Use of certain paint systems, long periods in harbor, long stays in warm waters, and/or exceeding of the service life of the paint systems will increase roughness greater than 60 NM.

It is not abnormal to expect savings of more than 3-4% through perfect hull maintenance.

04/21/2304/21/23 5252


12. Increasing Propeller Efficiency: Because of the propeller roughness, there will be

increase in propeller blade drag and will consume more power for achieving the same speed.

On some old hulls, reduction of propeller roughness

will tend to improve fuel consumption by engines and thereby energy conservation and CFP reduction will be achieved. The resulting carbon footprint reduction will be measured using the protocol established for this effort.

04/21/2304/21/23 5353


13. Engine Tuning & Overhauls:

The power output of engines decreases periodically due to wear & tear and carbon deposits. Periodic performance tuning of the engines can lead to complete fuel combustion and can result in increased efficiency.

04/21/2304/21/23 5454


Benefits: • This approach is relatively inexpensive, • Highly effective• Technologically low risk and

This is an economical, low risk/high reward method which will yield real life results in energy conservation and CFP reduction without any negative environmental impacts while incorporating these measures.
