To gain a better understanding of how the EEDI is designed and learn how to calculate and to work with the index in practice.

Entrance regulations

Participants should have technical knowledge about speed-power-revolution relation of ships, ship design in general and basic knowledge of marine propulsion.

Who should attend:
Shipping Companies: Management: Tech. Director (CTO), Managing Director (CEO), Inspection: Superintendent, Fleet Manager, Chief Operating Officer, CSO, Assistance; Quality / ISM: Designated Person; Commercial Dept.: Marketing and Sales Manager; Yard: Management: Tech. Director (CTO), Managing Director (CEO); Design: Design Manager, Engineers (Naval Architects); Quality: Quality Manager

Duration: 1 day

Since the initial adoption of the Kyoto Protocol in 1997 the subject of global warming and Greenhouse Gas (GHG) emissions has become a high profile international issue.
Although shipping is by far the most energy efficient mode of transport today, society has also started to look at CO2-emissions from ships with a critical eye. In 2003, the United Nations Framework Convention on Climate Change (UNFCCC) asked the IMO to initiate developments related to the reduction of GHGs from ships with a focus on cargo vessels.
Early work resulted in the so-called operational CO2-index which has now been renamed the Energy Efficiency Operational Indicator (EEOI). This operational indicator is seen today as a voluntary tool to complement the implementation of environmental management systems within the shipping industry.
Discussions at MEPC (IMO’s Marine Environment Protection Committee) also included market-based measures like emission trading and a marine bunker surcharge coupled with a compensation fund as alternative means to reduce emissions. However, no progress was achieved at the political level.
Discussions at IMO have therefore focused on the Energy Efficiency Design Index (EEDI), because here IMO – as the competent technical organization for newbuilding standards – is not obstructed by the emerging and developing countries in achieving a robust implementation. To resolve the debate about the term “CO2”, the “CO2 Design Index” originally chosen was renamed to “Energy Efficiency Design Index” at the request of the Chinese delegation.
The EEDI is an index for evaluating the potential transport efficiency of a ship. The theoretical CO2 emissions at 75% of the main engine power are expressed in relation to the corresponding ship speed at a defined draught.
Maritime Academy’s course is designed not only to give an overview of the IMO’s current development activities regarding the design index, but also to show participants how to calculate and to use the EEDI in practice.
Course participants will gain a better understanding of what the EEDI is all about, what is required to generate an EEDI Technical File (the base document for any verification and certification), how to calculate the design index and how to cope with special cases. Case studies will be used to illustrate the main parameters that have an impact on the design index.

The course focuses on:

  • Background to the EEDI
  • The role of IMO and UNFCCC
  • Introduction of other IMO and industry-driven GHG reduction measures
  • Calculation of the EEDI
  • Generation of the EEDI Technical File
