6.2 Marine evacuation systems
6.2.1 Construction of the marine evacuation systems
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 should be at least equal to:
or 10m2, whichever is the greater. However, Administrations may approve alternate arrangements which are demonstrated to comply with all the prescribed performance requirements*.
.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 occuring 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.
6.2.2 Performance of the marine evacuation system
6.2.2.1 A marine evacuation system shall be:
* Refer to the Recommendation on Testing of Life-saving appliances adopted by the Organization by resolution A689(17), as it may be amended.
