SOLAS regulation XII/8.3 requires
a triangle to be marked on the side shell of the ship when compliance
with regulation XII/6.2 involves
imposition of loading/operating restrictions as described in regulation XII/6.3. Such operating restrictions
only need to be imposed for solid bulk cargoes having a density of
1,780 kg/m3 and above, and apply at all times when solid
bulk cargoes having a density of 1,780 kg/m3 and above
are carried. The following interpretations should be followed when
determining if triangle marks are required:
1 When a ship's loading booklet restricts the
ship to carry solid bulk cargoes having a density of less than 1,780
kg/m3 , a triangle mark is not required, provided that
all reference to carriage of solid bulk cargoes having a density of
1,780 kg/m3 and above are removed from the loading booklet.
The loading booklet is to clearly specify that the ship is prohibited
from carrying solid bulk cargoes having a density of 1,780 kg/m3 and
above.
2 When a ship's deadweight is restricted, but
the load line assignment permits deeper draughts, and operating restrictions
in the form of draught or deadweight limits are imposed on the ship
to obtain compliance with the requirements, the loading booklet is
to clearly specify the operating restrictions and a triangle is to
be permanently marked on the ship's sides. If the ship's load line
and loading booklet are revised to limit the ship's draught at all
times, operating restrictions and the triangle marks are not required.
3 Where restrictions, other than a general restriction
to homogeneous loading, are imposed on the distribution of cargo in
the two foremost cargo holds as a condition of compliance, then the
loading booklet is to clearly specify the applicable operating restrictions
and a triangle is to be permanently marked on the ship's sides.
4 Where restrictions are imposed on the maximum
mass of packaged cargoes to be carried in the foremost cargo hold
as a condition of compliance with the Standards for the evaluation
of allowable hold loading of the foremost cargo hold, as contained
in annex 2 to 1997 SOLAS Conference resolution 4, the loading booklet
is to clearly state these limits, but the triangle marks are not required.
5 Where a homogeneous distribution of cargo in
the two foremost cargo holds is required as a condition of compliance,
then the loading booklet is to clearly specify the applicable operating
restrictions and a triangle is to be permanently marked on the ship's
sides.
