8 IHS Fairplay (IHSF) database is selected as
the standard database delivering the primary input data for the reference
line calculation. For the purpose of the EEDI reference line calculations,
a defined version of the database is archived as agreed between the
Secretariat and IHSF.
9 For the purpose of calculating the reference
lines, data relating to existing ships of 400 GT and above from the
IHSF database delivered in the period from 1 January 1999 to 1 January
2009 are used. For ro-ro cargo and ro-ro passenger ships, data relating
to existing ships of 400 GT and above from the IHSF database delivered
in the period from 1 January 1998 to 1 January 2010 are used.
10 The following data from the IHSF database on
ships with conventional propulsion systems is used when calculating
the reference lines:
-
.1 data on the ships' capacity is used as Capacity for each ship type as defined in MEPC.212(63);
-
.2 data on the ships' service speed is used as
reference speed V
ref
; and
-
.3 data on the ships' total installed main power
is used as MCRME(i)
.
11 For some ships, some data entries may be blank
or contain a zero (0) in the database. Datasets with blank power,
capacity and/or speed data should be removed from the reference line
calculations. For the purpose of later references, the omitted ships
should be listed with their IMO number.
12 To ensure a uniform interpretation, the association
of ship types defined in regulation 2 of MARPOL
Annex VI, with the ship types given by the IHSF database and
defined by the so-called Stat codes, is shown in the appendix to this
guideline. Table 1 in the appendix 1 lists the ship types from IHSF
used for the calculation of reference lines. Table 2 lists the IHSF
ship types not used when calculating the reference lines.
