8.4.1 Procedures followed in conducting the inclining
test and lightweight survey should be in accordance with the recommendations
laid out in annex 1 (Detailed guidance for the conduct of an inclining
test) to this Code.
8.4.1.1 Freeboard/draught readings should be taken
to establish the position of the waterline in order to determine the
displacement of the ship at the time of the inclining test. It is
recommended that at least five freeboard readings, approximately equally
spaced, be taken on each side of the ship or that all draught marks
(forward, midship and aft) be read on each side of the ship. Draught/
freeboard readings should be read immediately before or immediately
after the inclining test.
8.4.1.2 The standard test employs eight distinct
weight movements. Movement No.8, a recheck of the zero point, may
be omitted if a straight line plot is achieved after movement No.7.
If a straight line plot is achieved after the initial zero and six
weight movements, the inclining test is complete and the second check
at zero may be omitted. If a straight line plot is not achieved, those
weight movements that did not yield acceptable plotted points should
be repeated or explained.
8.4.2 A copy of the inclining data should be forwarded
to the Administration along with the calculated results of the inclining
test in an acceptable report format, if required.
8.4.3 All calculations performed during the inclining
test and in preparation of an inclining test report may be carried
out by a suitable computer program. Output generated by such a program
may be used for presentation of all or partial data and calculations
included in the test report if it is clear, concise, well documented,
and generally consistent in form and content with Administration requirements.
