9.1.1 One-man submersible atmospheric diving suits shall be so constructed as to be capable
of use in association with a lifting gear system which enables the suit to be
lowered into and recovered from the water with adequate safety factors for the
intended service.
9.1.2 If wires or ropes are incorporated for hoisting or lowering any submersible suit,
these shall have safety factors based upon the proven or calculated breaking
strength of the wire or rope.
9.1.3 The ADS is to be provided with primary lifting lugs or attachments designed to
support the entire weight of the ADS including the weight of the equipment, supplies
and pilot within the ADS. They are to be designed for forces of at least 2g vertical
(1g static plus 1g dynamic), 1g transverse and 1g longitudinal, unless otherwise
determined by the designer, acting simultaneously under the most severe loading
condition. Where appropriate, the increased loading due to other applicable loads
such as added mass including flooding of the compartment and drag are to be also
considered.
9.1.4 Additional lifting lugs or attachments are to be provided for emergency recovery of
the ADS. The emergency lifting lugs or attachments are to be designed for lifting
and raising the ADS to the surface under the heaviest emergency condition following
an accident.
9.1.5 The lifting gear system shall be subjected to static and dynamic load tests.
