9 For the purpose of these Guidelines, the definitions
given hereunder should apply, in accordance with the following figure.
9.1
Lifeboat release and retrieval system is
the means by which the lifeboat is connected to, and released from,
the lifeboat falls for lowering, launch and retrieval. It comprises
the hook assembly and operating mechanism.
9.2
Hook assembly is the mechanism,
attached to the lifeboat, which connects the lifeboat to the lifeboat
falls.
9.3
Movable hook component is that
part of the hook assembly in direct contact with the connection with
the lifeboat falls which moves to enable release from the falls.
9.4
Hook locking part is the component(s)
within a hook assembly which holds the movable hook component in the
closed position until activated by the operating mechanism to release
the hook. This activation may be performed through other components
within the hook assembly.
9.5
Operating mechanism is the means
by which the operator activates the opening, or release, of the movable
hook component. It includes the operating handle, linkages/cables
and hydrostatic interlock, if fitted.
9.6
Type, in relation to the design
of a lifeboat release and retrieval system, means an identical lifeboat
release and retrieval system of given safe working load, make and
model (thus any change to the materials of construction, design arrangement
or dimensions constitutes a change of type).
9.7
On-load release is the action
of opening the lifeboat release and retrieval system whilst there
is load on the hook assemblies.
9.8
Evaluation is a design review
and a performance test of a type of lifeboat release and retrieval
system.
9.9
Manufacturer, with respect to
existing lifeboat release and retrieval systems, is:
-
.1 the original equipment manufacturer; or
-
.2 a manufacturer of lifeboat release and retrieval
systems who has taken on the responsibility for a range or type of
lifeboat release and retrieval system; or
-
.3 any other person or entity which has taken
responsibility for a range or type of lifeboat release and retrieval
system when the original manufacturer no longer exists or supports
the equipment.
9.10
Modifications are changes to
the design of an approved lifeboat release and retrieval system which
may affect compliance with the original approval requirements or the
prescribed conditions for the use of the product.
9.11
New lifeboat release and retrieval
system is a lifeboat release and retrieval system that has
been approved in accordance with paragraph 4.4.7.6 of chapter IV of
the LSA Code, as amended by resolution MSC.320(89).
9.12
Existing lifeboat release and retrieval
system is a lifeboat release and retrieval system that has
not been approved in accordance with paragraph 4.4.7.6 of chapter
IV of the LSA Code, as amended by resolution
MSC.320(89).
