2.1 The Standards contained in this document
are based on the understanding that the manoeuvrability of ships can
be evaluated from the characteristics of conventional trial manoeuvres.
The following two methods can be used to demonstrate compliance with
these Standards:
-
.1 scale model tests and/or computer predictions
using mathematical models can be performed to predict compliance at
the design stage. In this case full-scale trials should be conducted
to validate these results. The ship should then be considered to meet
these Standards regardless of full-scale trial results, except where
the Administration determines that the prediction efforts were substandard
and/or the ship performance is in substantial disagreement with these
Standards; and
-
.2 the compliance with the Standards can be demonstrated
based on the results of the full-scale trials conducted in accordance
with the Standards. If a ship is found in substantial disagreement
with the Standards, then the Administration should take remedial action,
as appropriate.
