1 The reference lines are established for each
ship type to which regulation 21 (Required EEDI) of MARPOL Annex VI
is applicable. The purpose of the EEDI is to provide a fair basis
for comparison, to stimulate the development of more efficient ships
in general and to establish the minimum efficiency of new ships depending
on ship type and size. Hence, the reference lines for each ship type
is calculated in a transparent and robust manner.
2 Ship types are defined in regulation 2 of MARPOL Annex VI. The reference line for
each ship type is used for the determination of the required EEDI
as defined in regulation 21 of MARPOL Annex
VI.
3 These guidelines apply to the following ships
types: bulk carrier, gas carrier, tanker, containership, general cargo
ship, refrigerated cargo carrier, combination carrier, ro-ro cargo
ship, ro-ro cargo ship (vehicle), ro-ro passenger ship and LNG carrier.
It is noted that a method of calculating reference lines has not been
established for passenger ships other than cruise passenger ship having
non-conventional propulsion.
