3.1 Innovative energy efficiency technologies are allocated to category
(A), (B) and (C), depending on their characteristics and effects to the EEDI formula.
Furthermore, innovative energy efficiency technologies of category (B) and (C) are
categorized to two sub-categories (category (B-1) and (B-2), and (C-1) and (C-2),
respectively).
-
Category (A):
Technologies
that shift the power curve, which results in the change of combination
of PP
and Vref
: e.g.
when Vref
is kept constant, PP
will
be reduced and when PP
is kept constant, Vref
will be increased
-
Category (B):
Technologies
that reduce the propulsion power, PP, at Vref
,
but not generate electricity. The saved energy is counted as Peff
-
Category (B-1):
Technologies
which can be used at any time during the operation and thus the availability
factor (feff
) should be treated as 1.00.
-
Category (B-2):
Technologies
which can be used at their full output only under limited condition.
The setting of availability factor (feff
)
should be less than 1.00.
-
Category (C):
Technologies
that generate electricity. The saved energy is counted as PAEeff
-
Category (C-1):
Technologies
which can be used at any time during the operation and thus the availability
factor (feff
) should be treated as 1.00.
-
Category (C-2):
Technologies
which can be used at their full output only under limited condition.
The setting of availability factor (feff
)
should be less than 1.00.
