ANNEX 5
DRAFT AMENDMENTS TO THE CODE FOR THE
CONSTRUCTION AND EQUIPMENT
OF SHIPS CARRYING DANGEROUS CHEMICALS IN BULK (BCH CODE)
CHAPTER II - CARGO CONTAINMENT
1 The following new paragraph 2.14.3 is added after
existing paragraph 2.14.2
"2.14.3 The controlled tank venting systems as provided
in paragraph 2.14.2 above should consist of a primary and a
secondary means of allowing full flow relief of vapour to
prevent over-pressure or under-pressure in the event of
failure of one means. Alternatively, the secondary means may
consist of pressure sensors fitted in each tank with a
monitoring system in the ship's cargo control room or
position from which cargo operations are normally carried
out. Such monitoring equipment should also provide an alarm
facility which is activated by detection of over-pressure or
under-pressure conditions within a tank. Ships should comply
with the requirements of this paragraph by the date of the
first scheduled dry-docking after [date of entry into force
of the amendments], but not later than [3 years after the
date of entry into force of the amendments]."
2 Existing paragraphs 2.14.3 and 2.14.4 are renumbered as
paragraphs 2.14.4 and 2.14.5.
