Regulations on Energy Efficiency of Ships Aiming to reduce Green House Gas (GHG) emissions from ships and increase the energy efficiency of ships, Marine Environment Protection Committee of International Maritime Organisation (IMO) has adopted two major initiatives in July 2011 - Energy Efficiency Design Index (EEDI) for new ships and Ship Energy Efficiency Management Plan (SEEMP) for all ships - which have entered into force from January 2013. While the EEDI is in the hands of the shipbuilder, or the designer, the Ship Energy Efficiency Management is in the hands of the ship operator and the Charterer. The paper explores the various aspects of deploying the application of EEDI for all new ships and SEEMP for all existing ships in reducing Carbon Dioxide (CO 2) emissions and saving fuel cost from international shipping for every year up to year 2030.

arine Environment Protection Committee of International Maritime Organisation in July 2011 has adopted a set of technical requirements aimed to reduce Green House Gas (GHG) emissions from ships which includes two types of measures (1) Energy Efficiency Design Index (EEDI) for new ships and (2) Ship Energy Efficiency Management Plan (SEEMP) for all ships. These regulations have entered into force since 1 st January 2013.
While the EEDI is in the hands of the shipbuilder, or the designer, the Ship Energy Efficiency Management is in the hands of the ship operator and the Charterer. Technical design measures include the use of nonfossil fuels as well as further optimisation of engines, hull, and propeller. Operational measures include, inter alia, better utilisation of cargo capacity, better voyage planning to strike the right balance between times spent underway and fuel consumption, and enhanced energy efficiency in ship operation. Drawing an obvious parallel with the car industry, the technical design measures are clearly in the hands of the car manufacturer. The manufacturer can optimise the design for better fuel economy, test it under certain standardised design conditions, label it, and use this information to increase car sales. Merely because technical design measures and operational measures are separated, the customer is able to compare the standardised fuel economy of various cars, when choosing, and regulators are in a position to set minimum 12 |

standards. Operational measures are in the hands of the consumer and stimulated by other means. Study on IMO Energy Efficiency Measures As per a study commissioned by IMO (MEPC 63/INF.2 dated 31 October 2011), it is estimated that application of the EEDI for all new ships and SEEMP for all existing ships will reduce approximately 150 M tonnes of CO 2 from the atmosphere annually by 2020, depending on the growth in world trade. For 2030, the reduction will be approximately 330 M tonnes annually. The average annual fuel cost saving is estimated between USD 20 and USD 80 billion (average USD 50 billion) by 2020, and between USD 90 and USD 310 billion (average USD 200 billion) by 2030. Energy Efficiency Design Index (EEDI) The basic idea of the EEDI is to give each and every new vessel a calculable figure that will denote its emissions of CO 2 in relation to the amount of tonne-mile of cargo carried. It is not unlike the ratings given to fridges and cars today. Consider the following simplified EEDI formula: the CO 2 emission represents the total CO 2 emission from combustion of fuel, including propulsion and auxiliary engine sea load, taking into account the carbon content of the fuels in question. If innovative energy-efficient technologies are incorporated on a ship, their effects are deducted from the total CO 2 emission. The energy
