1 Energy Efficiency Design Index (EEDI): Norme IMO ed aspetti tecnici PORT&SHIPPINGTEC Green Shipping Summit Novembre 2011 Mario Dogliani Head, Corporate R&D RINA

2 Contents Regulatory background IMO & CO Technical aspects By the way.

3 Regulatory background SOx NOx CO2 1. Technical measures: Energy Efficiency Design Index (EEDI) new ships 2. Operational measures: Ship Energy Efficiency Management Plan (SEEMP) Energy Efficiency Operational Indicator (EEOI) 3. Marked Based Instruments

4 Regulatory background 1 August 2012 SOx emission limits 1 January 2016 NOx emission Tier III

5 IMO & CO 2 Energy efficiency measures adopted United States Caribbean Emission Control Area adopted Other Annex VI issues Guidelines for reception facilities under MARPOL Annex VI and for marine diesel engines fitted with selective catalytic reduction (SCR) systems adopted Draft amendments to the NOx Technical Code 2008, engines not pre-certified on a test bed and to NOx-reducing devices, approved Review of the status of technological developments to implement the Tier III agreed terms of reference MEPC 62 (July 2011) Resolution MEPC. (62) Adopted on 15 July 2011 New ships (EEDI) New and existing ships (SEEMP)

6 IMO & CO 2 Technical and operational measures 1. Technical measures: Energy Efficiency Design Index (EEDI) for new ships MEPC.1/Circ.681 Voluntary verification of the EEDI MEPC.1/Circ Operational measures: Ship Energy Efficiency Management Plan (SEEMP) MEPC.1/Circ.683 Energy Efficiency Operational Indicator (EEOI) MEPC.1/Circ.684

7 Technical aspects Impact on new and existing ships "New ship" means a ship:.1 for which the building contract is placed on or after 1 January 2013; or.2 in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction on or after 1 July 2013; or.3 the delivery of which is on or after 1 July For new ships, EEDI (Bulk Carrier, Gas tanker, Tanker, Container ship, General Cargo ships, Refrigerated cargo carrier, Combination carrier, passenger ships, ro-ro vehicle carriers, ro-ro cargo ships, ro-ro passenger ships) > 400 GT For existing ships, SEEMP on board on or after 1 January 2013 at the first intermediate or renewal survey, whichever is the first (> 400 GT)

8 Technical aspects Technical measures ENERGY EFFICIENCY DESIGN INDEX FOR NEW SHIPS (EEDI) - Will enable ship designers and builders to design and construct intrinsically efficient ships - Will encourage ship owners to invest in energy-efficiency technologies Operational measures SHIP ENERGY EFFICIENCY MANAGEMENT PLAN (SEEMP) Onboard management instrument (slower steaming; faster turnaround; special hull paints; heat recovery systems; etc) ENERGY EFFICIENCY OPERATIONAL INDICATOR enables ship-owners to measure the effectiveness of the adopted efficiency practices

9 Technical aspects SHIP ENERGY EFFICIENCY MANAGEMENT PLAN SEEMP ENERGY EFFICIENCY OPERATIONAL INDICATOR EEOI Planning Implementation Monitoring Self evaluation Improvement 1. Measuring energy-efficiency at each voyage 2. Identification of the critical phases of the operational management of the ship and carrying out of corrective measures 3. Evaluation of operational performance by owners or operators 4. Continued monitoring of individual ship 5. Evaluation of any changes made to the ship or its operation 9

10 Technical aspects Environmental cost EEDI = Benefit to Society Cost: emissions of CO 2 Benefit: cargo capacity & transport work Reduction targets X for Bulk Carriers dwt and above - built 1 Jan Dec 2014: X is 0 - built 1 Jan Dec 2019: X is 10 - built 1 Jan Dec 2024: X is 20 - built on or after 1 Jan 2025: X is 30 10

11 Technical aspects ENERGY EFFICIENCY OPERATIONAL INDICATOR EEOI Emission factor (gco2/t fuel) Tons of fuels used Number of voyages Carried cargo Nautical miles sailed Number of voyages 11

12 Technical aspects Many aspects still need to be discussed and finalized by future sessions of the MEPC. The agreed MEPC work plan includes the following: EEDI formula for all ship types and all types of propulsion guidelines for calculation of the EEDI (new ships) and for development of SEEMP (all ships); Guidelines on EEDI survey and certification 12

13 Technical aspects 13

14 Technical aspects Task 1- Refinement of the EEDI formula for RoRo passenger ships [..] broken down into 3 activities as follows: 1. based on the current MEPC baselines approach for the considered ship types, collect further data and, as far as reasonable and practicable, develop a proposed refined/adjusted formulation of such baseline approach; 2. identify possible correction factors to be included in the EEDI formula for the considered ship types. [ ] Validate the correction factors/new approach versus available and collected data; 3. [ ] relevant proposal(s) on further steps which the IMO may wish to consider. Task 2 collect information on similar and/or complementary studies underway [ ]. 14
