ANNEX 3
PROPOSED AMENDMENTS TO THE BCH CODE
RELATING TO
CONTROLLED CARGO TANK VENTING SYSTEMS
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 1 July
2002, but not later than 1 July 2005. However, the
Administration may approve relaxation of this paragraph
for small ships of less than 500 tons gross
tonnage."
2 Existing paragraphs 2.14.3 and 2.14.4 are
renumbered as paragraphs 2.14.4 and 2.14.5.
