1 The Committee, at its eightieth session (11
to 20 May 2005), after having considered the proposal by the forty-ninth
session of the Sub-Committee on Fire Protection regarding
review on the Guidelines for the approval of equivalent water-based
fire-extinguishing systems as referred to in SOLAS 74 for
machinery spaces and cargo pump-rooms (MSC/Circ.668 as amended by MSC/Circ.728),
approved Revised Guidelines for the approval of equivalent water-based
fire-extinguishing systems for machinery spaces and cargo
pump-rooms (MSC/Circ.1165).
2 The Sub-Committee on Fire Protection, at its
fifty-first session (5 to 9 February 2007), reviewed the Revised
Guidelines for the approval of equivalent water-based fire-extinguishing
systems for machinery spaces and cargo pump-rooms (MSC/Circ.1165) and, acknowledging figures
1, 2 and 3 in the Revised Guidelines did not clearly illustrate the
recommended fire test configurations and spray fire locations, revised
the aforementioned figures accordingly to clearly show the specified
test arrangements.
3 The Committee, at its eighty-third session (3
to 12 October 2007), after having considered the above proposal,
approved amendments to figures 1, 2 and 3 of the Revised Guidelines
for the approval of equivalent water-based fire-extinguishing
systems for machinery spaces and cargo pump-rooms (MSC/Circ.1165), as set out in the annex.
4 Member Governments are invited to apply
the amendments to the Revised Guidelines when approving equivalent
water-based fire-extinguishing systems for machinery spaces and
pump-rooms and bring them to the attention of ship designers,
shipowners, equipment manufacturers, test laboratories and other
parties concerned.
