2.1 The tables and formulae described in paragraph 3.2.2.3 of the Code are based on data
from ships having:
2.2 For ships with parameters outside the above
limits, the angle of roll (φ1) may be determined with
model experiments of a subject ship, following the procedure described
in the Guidelines as the alternative. In addition, the Administration
may accept such alternative determinations for any ship if deemed
appropriate.
2.3 The alternative means for determining the
wind heeling lever (⋉
w1
) may be accepted,
to the satisfaction of the Administration, as an equivalent to calculation
in paragraph 3.2.2.2 of the Code. When
such alternative tests are carried out, reference should be made to
the relevant part of the Guidelines. The wind speed used in the tests
should be 26 m/s in full scale with uniform velocity profile. The
value of wind speed used for ships in restricted services may be reduced
to the satisfaction of the Administration.
2.4 The test programme should be approved by Administration
in advance.
2.5 Tests should be documented by means of a report
and a video or other visual records containing all relevant information
on the model, the procedure and the test results, which should be
approved by the Administration.
2.6 Any procedure different from those provided
in the Guidelines should be subject to the approval of the Administration.
