(1) For vessels operating in areas where ice accretion
is likely to occur the following icing allowance shall be made in
the stability calculations:footnote
-
(a) 30 kg/m2 on exposed weather decks
and gangways;
-
(b) 7.5 kg/m2 for projected lateral
area of each side of the vessel above the water plane;
-
(c) the projected lateral area of discontinuous
surfaces of rail, spars (except masts) and rigging of vessels having
no sails and the projected lateral area of other small objects shall
be computed by increasing the total projected area of continuous surfaces
by 5% and the static moments of this are by 10%.
(2) Vessels intended for operation in areas where
ice accretion is known to occur shall be:
