2.8.1 Ships should be capable
of surviving the damage indicated in 2.5 with
the flooding assumptions in 2.7 to
the extent determined by the ship's type according to the following
standards:
-
.1 A type 1G ship should be assumed to sustain damage
anywhere in its length;
-
.2 A type 2G ship of more than 150 m in length should
be assumed to sustain damage anywhere in its length;
-
.3 A type 2G ship of 150 m in length or less should
be assumed to sustain damage anywhere in its length except involving either of the
bulkheads bounding a machinery space located aft;
-
.4 A type 2PG ship should be assumed to sustain
damage anywhere in its length except involving transverse bulkheads spaced further
apart than the longitudinal extent of damage as specified in 2.5.1.1.1;
-
.5 A type 3G ship of 125 m in length or more should
be assumed to sustain damage anywhere in its length except involving transverse
bulkheads spaced further apart than the longitudinal extent of damage specified in
2.5.1.1.1;
-
.6 A type 3G ship less than 125 m in length should be
assumed to sustain damage anywhere in its length except involving transverse
bulkheads spaced further apart than the longitudinal extent of damage specified in
2.5.1.1.1 and except damage involving the machinery space
when located aft. However, the ability to survive the flooding of the machinery
space should be considered by the Administration.
2.8.2 In the case of small type 2G/2PG and 3G ships which
do not comply in all respects with the appropriate requirements of 2.8.1.3, .4, and .6, special dispensations may only be considered by the
Administration provided that alternative measures can be taken which maintain the same
degree of safety. The nature of the alternative measures should be approved and clearly
stated and be available to the port Administration. Any such dispensation should be duly
noted on the International Certificate of Fitness for the Carriage of Liquefied Gases in
Bulk referred to in 1.5.4.
