6.2.1.1 The passage of the marine evacuation system
shall provide for safe descent of persons of various ages, sizes and
physical capabilities wearing approved lifejackets from the embarkation
station to the floating platform or survival craft.
6.2.1.2 Strength and construction of the passage
and platform shall be to the satisfaction of the Administration.
6.2.1.3 The platform if fitted shall be:
-
.1 such that sufficient buoyancy will be provided
for the working load. In the case of an inflatable platform, the main
buoyancy chambers, which for this purpose shall include any thwarts
or floor inflatable structural members are to meet the requirements
of section 4.2 based upon the platform
capacity except that the capacity shall be obtained by dividing by
0.25 the usable area given in paragraph 6.2.1.3.3;
-
.2 stable in a seaway and provide a safe working
area for the system operators;
-
.3 of sufficient area that will provide for the
securing of at least two liferafts for boarding and to accommodate
at least the number of persons that at any time are expected to be
on the platform. This usable platform area shall be at least equal
to:
or 10 m2, whichever is the greater. However,
Administrations may approve alternate arrangements which are demonstrated
to comply with all the prescribed performance requirements footnote.
-
.4 self draining;
-
.5 sub-divided in such a way that the loss of
gas from any one compartment will not restrict its operational use
as a means of evacuation. The buoyancy tubes shall be sub-divided
or protected against damage occurring from contact with the ship's
side;
-
.6 fitted with a stabilizing system to the satisfaction
of the Administration;
-
.7 restrained by a bowsing line or other positioning
systems which are designed to deploy automatically and if necessary,
to be capable of being adjusted to the position required for evacuation;
and
-
.8 provided with mooring and bowsing line patches
of sufficient strength to securely attach the largest inflatable liferaft
associated with the system.
6.2.1.4 If the passage gives direct access to
the survival craft, it should be provided with a quick release arrangement.
