7.1.1
footnote
Every passenger
ship regardless of size and every cargo ship having a length, as defined
in the International Convention on Load Lines, 1966, of 24 m and upwards,
should be inclined upon its completion and the elements of its stability
determined.footnote
7.1.2
footnote
Where any alterations
are made to a ship so as to materially affect the stability, the ship
should be re-inclined.footnote
7.1.3
footnote
At periodic intervals
not exceeding five years, a lightweight survey should be carried out
on all passenger ships to verify any changes in lightship displacement
and longitudinal centre of gravity. The ship should be re-inclined
whenever, in comparison with the approved stability information, a
deviation from the lightship displacement exceeding 2% or a deviation
of the longitudinal centre of gravity exceeding 1% of L is found,
or anticipated. footnote
7.1.4
footnote
The Administration
may allow the inclining test of an individual ship as required by
paragraph 7.1.1 to be dispensed with provided
basic stability data are available from the inclining test of a sister
ship and it is shown to the satisfaction of the Administration that
reliable stability information for the exempted ship can be obtained
from such basic data.footnote
7.1.5
footnote
The Administration
may allow the inclining test of an individual ship or class of ships
especially designed for the carriage of liquids or ore in bulk to
be dispensed with when reference to existing data for similar ships
clearly indicates that due to the ship's proportions and arrangements
more than sufficient metacentric height will be available in all probable
loading conditions. footnote
7.1.6 The inclining test prescribed is adaptable
for ships with a length below 24 m if special precautions are taken
to ensure the accuracy of the test procedure.
