The Energy Efficiency Design Index (EEDI) that is part of a new Chapter 4 of MARPOL Annex 6 on Energy Efficiency Regulations is mandatory for new ships effective 1 January 2013. During the period from 2011 to the end of 2012, many of the major shipyards and shipping companies have voluntarily complied with the requirements of EEDI calculation and verification for their newbuilds. This paper outlines requirements of EEDI verification procedure and aspects of the verification method that are important to the calculation of EEDI reference speed from speed trials. This paper shows the outcome of the verification process that some new ships have gone through, the degree of compliance achieved and the experience gained in EEDI verification for three types of ships: tankers, bulk carriers and containerships. Sources of uncertainties associated with lack of complete information from sea trials are identified. Comparison of the attained and required EEDI for the three vessel types demonstrating the degree of compliance in Phases 0 and 1 are included.
