EEDI verification

Providing assurance through assessment of design efficiency

Verification from Lloyd’s Register helps you demonstrate compliance against the required EEDI for your ship. We work closely with owners and shipyards at the design and build stages to help ensure peace of mind throughout.

CO2 emissions from shipping will be controlled through new IMO legislation which comes into force on January 1, 2013. From this date, new ships* will need to be designed and built to comply with the Energy Efficiency Design Index (EEDI).

The EEDI is a formula for calculating ships’ specific CO2 emissions per tonne mile. It is assessed using information relating to a ship’s machinery or the technologies being used on board, and its capacity to perform useful work at a certain speed.

Verification from Lloyd’s Register helps you demonstrate compliance against the required EEDI for your ship. We work closely with owners and shipyards at the design and build stages to help ensure peace of mind throughout. 

*specific ship types and sizes have been selected for initial implementation, including bulk carriers, tankers, gas carriers, container ships, general cargo ships, refrigerated cargo ships, combination carriers, passenger ships and ro-ros (vehicle and volume carriers). 

What is the EEDI?

The EEDI will apply to new ships* over 400 gt, or ships that have undergone major conversion. The EEDI formula calculates the CO2 produced by the ship’s propulsion and auxiliary power systems and any secondary energy usage by machinery such as shaft propulsion motors and generators. Any CO2 saved through innovative energy saving technologies like kites or sails is then subtracted. The resulting CO2 figure is divided by the ship’s transport work or ‘benefit to society’ (in effect, the ship’s capacity multiplied by its speed) to arrive at the final EEDI in grams per tonne-mile of CO2 produced.

Verification from Lloyd’s Register

Each ship will need to have verification of the ‘attained’ EEDI value at both the design stage (pre-verification) and the build stage prior to delivery (final verification). This process ensures that the EEDI value for the ship is less than the value required by the baseline (reference line) for that ship type and size.

Until the EEDI becomes mandatory, we can provide voluntary verification for new ships, for owners who wish to take a strategic position in early EEDI adoption.

As a recognised organisation, Lloyd’s Register is well placed to provide EEDI verification, both for voluntary adoption and on behalf of the various flag-states when it becomes mandatory. By choosing EEDI verification from Lloyd’s Register, you benefit from support and assurance, built on our technical expertise, throughout the design and build process.

Our commitment

As part of the verification process, we will:

• work closely with owners and yards to deliver assurance

• advise on key aspects of the verification process

• ensure comprehensive and consistent certification is carried out for individual ships and sister ships

• support your individual requirements.

EEDI reduction

In future years, the EEDI’s regulatory mechanism will allow CO2 to be controlled in much the same way that MARPOL Annex VI has regulated NOX and SOX emissions – through phased reductions in limits. These reductions will reduce the required EEDI value for each ship type and size by the following amounts:

Phase 0 – 0% (mandatory introduction)
Phase 1 – 10%
Phase 2 – 15/20% (depending on the ship type)
Phase 3 – 30%.

The reductions will not apply to passenger ships or ro-ros (vehicle and volume carriers) once the EEDI is mandatory.

In order to reduce the EEDI for a new ship, a number of measures are possible including:

• optimised hull design

• optimising main and auxiliary machinery

• use of innovative energy saving technologies

• use of low-carbon fuel and renewable energy

• reduction in lightweight and increase in cargo capacity design for slower speed. 

How is the EEDI used?

An EEDI certificate is valid for the life of a ship unless it undergoes a major conversion, in which case it will require re-verification. Together with a Ship Energy Efficiency Management Plan (SEEMP), the EEDI will form part of an International Energy Efficiency Certificate (IEEC) which is specific to each ship and must be maintained on board as part of normal inspection and audit.
