The following operational matters should be considered in
relation to stability criteria under section 2 of the Guidelines.
1 The stability criteria mentioned in the IS Code are minimum values; no maximum values are
recommended. It is advisable to avoid excessive values, since these
might lead to acceleration forces which could be prejudicial to the
vessel, its complement, its equipment and the safe carriage of the
cargo.
2 Where anti-rolling devices are installed in
a vessel, the Administration should be satisfied that the stability
criteria in the IS Code can be maintained when the devices are in
operation.
3 A number of factors such as beam wind on a vessel
with large windage area, icing, rolling characteristics, following
seas, etc., adversely affect stability and the Administration is advised
to take these into account in so far as is deemed necessary.
