Verification of the Attained EEDI for major conversions

In case of a major conversion, the ship-owner should submit to a verifier an application for an Additional Survey with the EEDI Technical File duly revised based on the conversion made and other relevant background documents. The background documents should include at least but are not limited to:

  • Documents explaining details of the conversion.
  • EEDI parameters changed after the conversion.
  • Reasons for other changes made in the EEDI Technical File.
  • Calculated value of the attained EEDI, with the calculation summary for each value of the calculation parameters and the calculation process.

The verifier normally will make sure that as a result of the major conversion, EEDI has not increased. In case of such an increase, the verifier will define the scope for sea trails, if any, and other activities to ensure compliance with regulation (MariEMS 2017).
