1 In paragraph 11.1.1, subparagraphs .4 to .6
are replaced by the following subparagraphs:
-
“.4 regulation 10.5.6 shall apply to ships
of 2,000 gross tonnage and over;
-
.5 the provisions of 11.3 shall apply in lieu
of regulation 10.8;
-
.6 the provisions of 11.2 shall apply in lieu
of regulation 10.9;
-
.7 regulation 4.5.10 shall apply to ships of 500
gross tonnage and over, replacing “hydrocarbon gases”
by “flammable vapours” in the regulation; and
-
.8 regulations 13.3.4 and 13.4.3 shall apply to
ships of 500 gross tonnage and over.”
2 In paragraph 11.1, the following new paragraph
11.1.4 is added:
-
“11.1.4 In lieu of the provisions of SOLAS regulation II-2/1.6.7, the requirements
of regulations II-2/4.5.10.1.1 and 4.5.10.1.4 and a system for continuous
monitoring of the concentration of flammable vapours shall be fitted
on ships of 500 gross tonnage and over which were constructed before
[the date of entry into force of the amendment] by the date of the
first scheduled dry-docking after [the date of entry into force of
the amendment], but not later than [3 years after the date of entry
into force of the amendment]. Sampling points or detector heads should
be located in suitable positions in order that potentially dangerous
leakages are readily detected. When the flammable vapour concentration
reaches a pre-set level which shall not be higher than 10% of the
lower flammable limit, a continuous audible and visual alarm signal
shall be automatically effected in the pump-room and cargo control
room to alert personnel to the potential hazard. However, existing
monitoring systems already fitted having a pre-set level not greater
than 30% of the lower flammable limit may be accepted. Notwithstanding
the above provisions, the Administration may exempt ships not engaged
on international voyages from those requirements.”
